21 Best Hikes In Glacier National Park For Every Skill Level

Glacier National Park, known as the “Crown of the Continent” has some of the most stunning and diverse hiking trails in North America. In fact, my favorite hike in the entire United States is on this list! This list includes all of the best hikes in Glacier National Park, plus a few easy ones, hikes under 5-miles, and can’t-miss trails for your next visit.

Hiking in Glacier National Park had been on my bucket list for years and it blew my expectations out of the water once I finally visited.

Whether you’re a seasoned hiker or just lacing up your boots for the first time, there’s a trail for you in this guide to the 21 best hikes in Glacier National Park.

Best Time For Hiking Glacier National Park

The best time to hike in Glacier National Park is from July to early September when the trails are generally clear of snow and the weather is most stable. However, this is also the peak season, so plan for early morning starts to beat the crowds.

Glacier National Park is comprised of 8 different areas (Belly River, Goat Haunt, Lake McDonald, Many Glacier, North Fork, St. Mary, Two Medicine and Walton). A majority of Glacier National Park hikes can be found along Going-To-The-Sun road, which cuts across the park through McDonald and St Mary areas.

Glacier National Park In September

I visited Glacier National Park right after their peak season ended, during the middle of September. I found this was a great way to see the park during good weather, still have enough other hikers on the trails so I felt comfortable solo hiking, and avoid massive crowds and trailhead parking headaches.

Best Easy Hikes In Glacier National Park

There are plenty of easy hikes in Glacier National Park.

These are my top picks in Glacier National Park for non hikers or anyone with mobility concerns.

#1 Trail of the Cedars Hike In Glacier National Park

  • Distance: 0.9 mile
  • Elevation Gain: 49 feet
  • Rating: Easy
  • Time To Hike: 30 minutes
  • Location: Lake McDonald Area
  • Trailhead: Trail of the Cedars
Trail of the Cedars easy hike in Glacier National Park

The Trail of the Cedars is one of the most accessible hikes in Glacier National Park for non hikers. It is an easy, flat loop that spans approximately 0.9 miles and is well-known for its accessibility, including being stroller and wheelchair-friendly. 

This trail takes visitors through a lush, old-growth cedar forest and alongside the beautiful Avalanche Creek. The path is a combination of boardwalk and pavement, making it a leisurely walk suitable for everyone. 

My Experience Hiking Trail Of The Cedars:

I completed Trail of the Cedars after hiking Avalanche Lake Trail. I thought it was a good way to cool down, and the smells from the Cedar trees were incredible. The trail was a bit crowded, but I was hiking it during the middle of the afternoon when the crowds are the largest.

I recommend coming first-thing in the morning if you want a more peaceful experience (and the parking lot is tiny and fills quickly).

#2 Baring Falls Hike In Glacier National park

  • Distance: 0.7 miles
  • Elevation Gain: 111 feet
  • Rating: Easy
  • Time To Hike: 30 minutes
  • Location: St Mary Area
  • Trailhead: Siyeh Pass Trailhead (alt option: Sun Point)
Baring Falls best hikes in glacier national park

Baring Falls is a relatively easy and one of the best family hikes in glacier national park. The trail is known for its accessibility and the beautiful waterfall that serves as the highlight of the short trek. It’s not often you find such a great waterfall on such a short trail! Luckily, Glacier National Park has several easy to reach waterfalls.

During peak season the small trailhead parking can become full, so I recommend an alternative route from Sun Point via Piegan Pass because there is more parking at the Sun Point lot.

I also recommend you extend your hike to St. Mary Falls and Virginia Falls, which can be accessed from the same parking area. It’s a longer route and the opportunity to see multiple waterfalls in one hike.

#3 Running Eagle Falls (aka Trick Falls)

  • Distance: 0.7 miles
  • Elevation Gain: 29 feet
  • Rating: Easy
  • Time To Hike: 15-30 minutes
  • Location: Two Medicine Area
  • Trailhead: Running Eagle Falls Trailhead in Two Medicine
Running Eagle Falls, aka Trick Falls, glacier national park hike

Running Eagle Falls, also known as Trick Falls, is known for its unique two-tiered waterfall, which can appear as one or two falls depending on the amount of water flow and the season. Fun fact: the falls are named after a female Blackfeet warrior, Running Eagle.

This trail to one of the best waterfalls in Glacier National Park, is well-maintained and extremely short and easy! 

Best Short Hikes In Glacier National Park Under 5 Miles

One of the things I love the most about Glacier is how many trail options there are. If you’re looking to tack on a short hike in the evening after a full day hike on one of the longer trails, or if you’re hoping to explore the park without clocking tons of miles each day there are options for you!

These are my favorite hikes in Glacier National Park under 5 miles.

#4 Johns Lake Loop

  • Distance: 2.0 miles
  • Elevation Gain: 190 feet
  • Rating: Easy
  • Time To Hike: <1 hour
  • Location: Lake McDonald Area
  • Trailhead: Johns Lake Loop Trailhead, Near Lake McDonald Lodge
Johns Lake Loop hike in Glacier National Park

Johns Lake Loop is one of the best easy hikes at Glacier National Park. It’s relatively flat which makes it one of the best family hikes that Glacier has to offer.

Scenery includes forests, lakes, and waterfalls – this trail has it all! The trail is known for its accessibility and the peaceful beauty of Johns Lake. 

#5 Upper McDonald Creek Trail

  • Distance: 5.6 miles
  • Elevation Gain: 278 feet
  • Rating: Easy
  • Time To Hike: 1.5-2 hours
  • Location: Lake McDonald Area
  • Trailhead: Upper McDonald Creek Trailhead, Near Upper Lake McDonald Ranger Station
Upper McDonald creek Glacier National Park hikes

This trail offers a relatively easy hike that follows along McDonald Creek, which is the largest stream in Glacier National Park. The creek itself is fed by glacial runoff, which gives it it’s stunning, clear water.

The trail is well-maintained and offers several viewpoints and access points to the creek, making it a refreshing stop on a hot day if you wish to dip your toes in the cool water!

While this trail is technically just over 5 miles, I’m still including it on the list of the best short hikes in Glacier National Park under 5 miles given it’s low elevation change and “easy” trail rating.

#6 St Mary & Virginia Falls

  • Distance: 3.1 miles
  • Elevation Gain: 452 feet
  • Rating: Moderate
  • Time To Hike: 1-2 hours
  • Location: St Mary Area
  • Trailhead: St. Mary Falls Shuttle Stop
St Mary Falls glacier national park hikes

This hike is a two-for-one deal, with views of two famous waterfalls. The trail is well-maintained and suitable for all skill levels, including non hikers and anyone with mobility challenges. There are a few steeper sections, but I believe anyone can manage this trail by taking it at your own pace.

First up on the trail is the impressive St. Mary Falls, which cascades in a series of drops. 

Continuing on, the trail leads to Virginia Falls. Virginia Falls plummets with a powerful force, and there’s usually a spot where you can feel the mist on your face – a refreshing break on a warm day!

Pro tip: pack your bathing suit for this trail! There are some popular places where you can get in the water (just know it’s usually cold all year long!)

#7 Swiftcurrent Nature Trail

  • Distance: 2.6 miles
  • Elevation Gain: 127 feet
  • Rating: Easy
  • Time To Hike: 1-2 hours
  • Location: Many Glacier Area
  • Trailhead: Many Glacier Hotel (alternative option to start loop from Grinnell Glacier Trailhead)
Swiftcurrent Nature Trail, easy hikes in glacier national park

The Swiftcurrent Nature Trail is known for being an accessible and family-friendly hike that offers stunning views of the Swiftcurrent Lake and the surrounding mountain scenery.

It’s located near the Many Glacier campground in Glacier National Park. Or, if you’re lucky enough to snag a room at Many Glacier Hotel this trail is right outside it’s front door!

It’s a relatively flat trail around the lake, which makes it the perfect easy hike at Glacier National Park under 5 miles.

#8 Apikuni Falls Hike In Glacier National Park

  • Distance: 1.8 miles
  • Elevation Gain: 580 feet
  • Rating: Moderate
  • Time To Hike: 1-1.5 hours
  • Location: Many Glacier Area
  • Trailhead: Apikuni Parking Area
Apikuni Falls glacier national park hike

Apikuni Falls is a short but steep hike to a huge waterfall. The well-maintained trail to Apikuni Falls is relatively short, albeit steep, making it an excellent option for a quick adventure if you’re looking for a short but somewhat strenuous hike in the park.

The hike usually starts at the Apikuni parking area, which is a small pullout on the Many Glacier Road with very limited parking. From there, the trail heads up through open terrain, so you’ll get great views of the surrounding mountains.

The waterfall is impressive, especially during the spring and early summer when the snowmelt is at its peak. You can even get quite close to the falls.

Wildlife sightings on this trail include bighorn sheep and bears, so you should be prepared with bear spray and knowledge of wildlife safety!

Most Scenic Hikes In Glacier National Park

Honestly, just about every trail in the park could be considered scenic. However, these 4 hikes are my personal favorites, and what I’d classify as the most scenic hikes in Glacier National Park overall.

Number 12 (Grinnell Glacier) is my favorite hike of all time, surpassing hikes in New Zealand and Iceland.

#9 Avalanche Lake

  • Distance: 5.9 miles
  • Elevation Gain: 757 feet
  • Rating: Moderate
  • Time To Hike: 2-3 hours
  • Location: Lake McDonald Area
  • Trailhead: Trail of the Cedars
Avalanche Lake Trail hike in Glacier National Park

Avalanche Lake is a very popular hike in Glacier National Park. The trail to Avalanche Lake begins from the Trail of the Cedars and then branches off to follow the Avalanche Creek gorge.

I recommend combining Avalanche Lake hike with Trail of the Cedars so you only have to battle for a parking spot once, since they share the same trailhead.

The view of the lake with the waterfalls in the background is an iconic shot of Glacier National Park. Waterfalls cascade down these cliffs, feeding into the lake, making for a dramatic backdrop.

While the waterfalls are more visible during spring and summer (they’re fed by snowmelt), I was still able to see them during my visit to Glacier National Park in September.

Wildlife sightings, including deer, bears, and a variety of birds, are possible, so you should be prepared and aware of your surroundings. I only saw chipmunks on this hike. Unless you’re going first thing in the morning, it’s unlikely you’ll see much wildlife because the crowds will scare them off during the day.

However, I did hear a story from a friend that while she was picnicking at Avalanche Lake a ranger showed up and told everyone to hike back immediately and as one large group because there were bears present on the trail. This is very rare and shouldn’t scare you off. The rangers in the park take bear safety very seriously and if there are major concerns about bear encounters they close the trail temporarily.

Given the popularity of the trail, I recommend you start early in the day to secure parking (it’s a small trailhead parking lot) and enjoy the trail with fewer people.

My Experience Hiking Avalanche Lake Trail:

I hiked Avalanche Lake first thing in the morning. By 8AM the trailhead parking lot was already starting to fill, even in the off season.

This trail holds a spot on my top 3 favorite hikes in Glacier National Park, and it was a great hike to start the day with.

I kept hiking when I reached the lake, even though many people turned around when they reached the first shoreline. The opposite end of the lake was far less crowded and I ate my lunch along the water, only seeing 2 other groups the entire time I was there.

#10 Highline Trail

  • Distance: 14.9 miles
  • Elevation Gain: 2,621 feet
  • Rating: Hard
  • Time To Hike: 6-8 hours
  • Location: St Mary Area
  • Trailhead: Logan Pass Visitor Center
Highline trail best hikes in glacier national park
The views from Highline Trail are unreal

The Highline Trail is one of the most famous and scenic hikes in Glacier National Park. It’s known for its stunning views of the surrounding mountains and valleys. I was truly blown away.

The trail typically starts at the Logan Pass Visitor Center and follows the Continental Divide. You will immediately hit panoramic views and the ropes section. Alternately, you can start Highline Trail at The Loop and hike in the opposite direction – keep in mind there is very limited parking at The Loop trailhead.

Highline Trail is not for the faint of heart due to the steep drop-offs, but it is equipped with a hand cable in the most daunting section for safety. I hiked from Logan Pass towards The Loop first thing in the morning. The ropes section is shaded during that time of the day, which meant there was a bit of ice and the cables are cold – I highly recommend bringing gloves for this section, and possibly traction devices for your hiking boots.

I recommended this trail for experienced hikers, especially those who have no issues with heights. The trail also offers a side trip to the Grinnell Glacier Overlook, which is a steep but incredible detour.

Highline Trail safety rail

My Experience Hiking Highline Trail In Glacier National Park:

I hiked Highline Trail after completing Hidden Lake. Both hikes start from Logan Pass Visitor Center so it’s easy to combine the two. However, given the length of Highline Trail and my late start I didn’t complete it. I only hiked a few miles in and back out, which was still worth it because the views I saw are incredible.

Even starting late in the morning the beginning of the trail was still covered in ice. This, combined with hiking along the edge of a very steep overhang is a little disorienting. If I were scared of heights I’d probably feel differently about this hike.

While I did not spot any bears on this trail, I did see some mountain goats!

#11 Hidden Lake

  • Distance: 5.1 miles
  • Elevation Gain: 1,338 feet
  • Rating: Moderate
  • Time To Hike: 3-4 hours
  • Location: St Mary Area
  • Trailhead: Logan Pass Visitor Center
Hidden Lake best hikes in glacier national park

Hidden Lake is one of the most popular hikes in Glacier National Park, known for its breathtaking views and the opportunity to see a variety of wildlife! The trail starts at the Logan Pass Visitor Center, which is easily accessible via the Going-to-the-Sun Road.

The first portion of the trail is also the trail for Hidden Lake Overlook. The overlook is an easy hike in Glacier National Park and a good alternative option that still allows you to see Hidden Lake.

The overlook trail is about 2.7 miles total, and the path to the overlook is relatively flat, with some of it consisting of raised wooden walkways. Past the overlook the trail is considered more strenuous.

Views along Hidden Lake Overlook hike

In the summer months you’ll find incredible wildflower meadows. During my visit to Glacier National Park in September the fields were dusted with snow but many of the wildflowers were still visible. Additionally, the biggest chipmunks I’ve ever seen were on this hike.

Me hiking down to Hidden Lake, best hikes in glacier national park

My Experience Hiking Hidden Lake Trail In Glacier National Park:

This is easily one of my favorite hikes in Glacier National Park! I started hiking to Hidden Lake around 8am in the morning during mid-September and the snow coming down at Logan Pass was so thick you couldn’t see more than 10 feet in front of me.

This isn’t uncommon for September, especially due to the high altitude, but not all travelers packed gloves and the visitor center sold out! Snow also made the boardwalk portion of the trail very slippery for me.

My hike down to Hidden Lake was busy until I reached the overlook. This is where most people turned around, and only a few of us continued on down to the lake.

The trail was well marked until the very end, but it was still easy to navigate to the lake. This is one of those “upside down” hikes, where you descend on the way to the end and then climb your way back out – a lot like hiking into the Grand Canyon. Make sure you save enough energy to get back up.

Hiking back to the top the first half mile is brutal. It’s basically endless stairs and I was feeling it in my legs by the time I made it back to the meadows section. Even so, this is still my second favorite hike in Glacier- it’s incredibly scenic, I enjoyed the changing weather patterns, and I even found some fresh grizzly prints in the mud by the lake.

One of the rangers I met on this trail mentioned that a park visitor had witnessed a wolverine hunt a moose. I cannot even imagine seeing something so rare, but this would be the trail to find some incredible wildlife because of the meadows, lakes and remoteness.

#12 Grinnell Glacier Trail

  • Distance: 10 miles
  • Elevation Gain: 2,047 feet
  • Rating: Hard
  • Time To Hike: 5-8 hours
  • Location: Many Glacier Area
  • Trailhead: Grinnell Glacier Trailhead, near Many Glacier Lodge
Grinnell Glacier in Glacier National Park

This trail is my personal favorite and arguably the best hike in the United States.

Grinnell Glacier Trail is one of the most scenic hikes in Glacier National Park, offering breathtaking views (one after another) of alpine meadows, dramatic cliffs, and pristine deep blue lakes.

It’s known for its stunning vistas of Grinnell Glacier and the surrounding peaks. The trail is rated as strenuous due to its length and the elevation gain involved, however, I believe that anybody can complete this trail if you move at your own pace and come prepared.

Grinnell Glacier trail glacier national park hike

Expect a round trip of about 10 miles. There is an optional boat across Swiftcurrent and Josephine Lakes, which can shorten the hike but only saves you mileage and not elevation. Additionally, it won’t save you much time because you can hike just as fast as the boat can travel. The trail typically takes between 6 to 8 hours to complete.

My Experience Hiking Grinnell Glacier In Glacier National Park:

I have been to a lot of National Parks, and not only is Glacier National Park my favorite one visited so far, but Grinnell Glacier Trail is my favorite trail I’ve hiked to date.

I was stunned by the beautiful lakes and constant beautiful views – they just kept getting better! I also saw mountain goats on this hike. 

I recommend getting an early start to avoid crowds, get one of the limited parking spaces and have enough time to enjoy lunch at the glacier.

Or, if you’re like me, the glacier is too cold and windy – instead I backtracked to the treeline to eat my lunch with some shelter from the wind. Bonus: there’s an outhouse toilet just before the summit.

While there weren’t many people on the trail on my way to the glacier, by the time I was headed back to the trailhead (early afternoon) the trail was getting congested. It’s not very wide in some areas, so there were frequent traffic jams when uphill hikers were trying to pass downhill hikers.

I always pack a few extra layers when I hike but I rarely use them. The wind at the top of this hike was so cold I ended up layering on everything I could find in my backpack.

Gloves and something to cover your ears are essential on this trail, even in summer months.

Best Hiking Boots For Glacier National Park

My absolute favorite hiking boots for Glacier National Park are my Danner Inquire Chukka Mid Hiking Boots.

  • There’s no break-in period – they’re comfy right out of the box.
  • I’ve hiked hundreds of miles in these and they’re still in great condition.
  • They’re waterproof – which makes them perfect for snowy, cold-weather hiking.

Siyeh Pass Trail glacier national park hikes

Siyeh Pass is a strenuous hike that rewards with one of the most dramatic views in Glacier National Park. As you ascend, you’ll be treated to views of the Sexton Glacier and the expansive Piegan Glacier. They’re stunning. The pass itself sits at an elevation of over 8,000 feet, so be prepared with gloves and a hat because it can get windy and cold.

Siyeh Pass Trail is a point-to-point trail that is 9.8 miles in one direction. You can start from either the Siyeh Pass Trailhead or the Piegan Pass Trailhead.

Due to the elevation and open terrain, weather can change rapidly, and it’s essential to be prepared for all conditions.

Wildlife sightings may include mountain goats, bighorn sheep, and the occasional bear, so carrying bear spray and knowing how to use it is crucial.

Be Bear Aware

Practicing bear safety on trails, particularly in Grizzly territory, is important for keeping you and the wildlife safe.

Remember to:
Always carry bear spray. You should be able to access your spray in <4 seconds. I keep mine in a holster for easy access.
– Hike in groups of 3 or more people, when possible.
– Make loud noise by singing or shouting ‘hey bear’ so you don’t surprise a bear. I also carry a bear bell on my backpack and my dogs collar for extra noise.

#15 Piegan Pass Trail

  • Distance: 16 miles
  • Elevation Gain: 3,077 feet
  • Rating: Hard

Cracker Lake glacier national park hike

Cracker Lake Trail in Glacier National Park is renowned for its strikingly vibrant blue lake, which is the result of glacial silt suspended in the water.

The trail to Cracker Lake starts near the Many Glacier Hotel and winds through dense forests, open meadows, and alpine terrain. 

Expect a moderate to strenuous hike, and the chance to see a variety of wildlife, including grizzly bears, which are quite active in the Many Glacier area.

I have major regrets for not hiking this trail. A friend of mine had been shortly before I planned to hike it solo and mentioned a good amount of Grizzly activity so I let fear keep me away. Next time I visit Glacier National Park I will absolutely hike this insanely gorgeous trail.

#17 Swiftcurrent Pass

  • Distance: 16.6 miles

This is definitely one of the harder hikes in Glacier National Park, but the scenery is worth it. This is also one of the best backpacking trails in glacier national park, so you can consider making it a multi-day hike.

The pass itself is a high mountain pass that offers breathtaking views, and on a clear day you might see a vast expanse of the park’s interior. Due to the elevation and exposure, weather conditions can change rapidly, so I recommend being prepared with layers and to check the weather forecast before setting out.

Hiking Many Glacier

Even if you’re planning a shorter 3-day trip to Glacier National Park do not miss out on hiking Many Glacier. This area of the park is, in my opinion, the most iconic section with the best hiking views.

I recommend staying in Many Glacier for these hikes. There are lots of camping and hotel options in Glacier National Park which will make it more convenient to access these hiking trails.

#19 Redrock Falls

The hike is considered strenuous due to its length and the elevation gain involved. It starts near the Many Glacier Hotel and follows the Ptarmigan Trail.

#21 Iceberg Lake

  • Distance: 9.6 miles
  • Elevation Gain: 1,459 feet
  • Rating: Moderate
  • Time To Hike: 4-6 hours

  • Trailhead: Many Glacier Hotel
Iceberg Lake hike in Glacier National Park

Iceberg Lake is a moderately strenuous hike that leads to a stunning alpine lake where icebergs float well into the summer! The trail offers spectacular wildflower displays and the chance to see some wildlife.

However, the highlight of the hike is reaching Iceberg Lake itself, which is nestled against a backdrop of steep cliffs. The lake is often dotted with icebergs that have calved from the surrounding glaciers, even in the summer months.

I highly recommend an early start to secure parking and to avoid the afternoon crowds.

About My Experience Hiking Glacier National Park

Because I travel in my camper van I was able to visit the park right after peak-season ended (Labor day) and stay for a few weeks to explore the park in-depth and experience the best hikes in Glacier National Park.

Glacier National Park holds the top spot on my favorite US National Parks list.

My favorite hikes (in order) were Grinnell Glacier, Hidden Lake and Avalanche Lake.

I visited the first two weeks in September. This was ideal because there are far fewer crowds but the weather hasn’t gotten too cold. The downside is that shuttles (like the Swiftcurrent Lake boat and the shuttle bus for Highline Trail) were no longer operating, which made point-to-point hikes more difficult without a return shuttle to take me back to my vehicle.

Important Information For Glacier National Park Day Hikes

When planning your day hikes in Glacier National Park, it’s essential to be prepared. Here are some key points to keep in mind:

  • Carry bear spray: The park is home to both black and grizzly bears. Carrying bear spray and knowing how to use it can help deter an encounter.
  • Check for trail closings: Due to wildlife activity or maintenance, trails may be closed. Always check the current trail status before heading out.
  • Safety In Glacier National Park: Always keep a safe distance from wildlife. Feeding or approaching wildlife is dangerous and illegal. Glacier National Park rangers are very vocal about not feeding bears, as this endangers the bear and other park visitors.
  • Timed Entry Vehicle Reservations: During peak seasons, the park may implement a timed entry system to manage crowds. Be sure to check if this applies to your visit. In the past, Glacier National Park has implemented timed entry for visitors arriving between the end of May and early September. Specifics change year-to-year.
  • Wear layers: The weather changes rapidly in the mountains. Dressing in layers, even during summer months, will allow you to adjust to varying conditions.
  • Cell Service Inside The Park: There is no cell service in Glacier National Park. Be sure to download your maps before you visit. I recommend AllTrails Plus for hiking so you can download your hiking maps and get off-trail alerts if you accidentally detour.
  • Park entrance: An entrance fee is required to enter Glacier National Park, it’s $35 per vehicle (good for 7 days) or you can enter with the America The Beautiful park pass which is $80 annually. The park pass pays off if you plan to visit more than 2 parks per year. Park entrance fees are different than vehicle reservations.

Best Hikes To See Wildlife In Glacier National Park

If you’re hoping to spot some wildlife in Glacier National Park these are the hiking trails where you’re most likely to see bears, moose, bighorn sheep or mountain goats!

FAQs About Hiking In Glacier National Park

Do I need a permit to hike in Glacier National Park? 

For day hikes, no permit is required. However, if you plan to camp overnight in the backcountry, you will need a backcountry permit. All park visitors must pay an entry fee.

If you visit Glacier National Park during the summer you may also need a timed-entry pass to enter in your vehicle.

What is the best time of year to hike in Glacier National Park? 

The best time to hike in Glacier National Park is from late June to September when most trails are snow-free and accessible.

Going-To-The-Sun road may not open until early July, so always check ahead. Many trailheads are located along GTS road and if it’s not open, you cannot get to the trail.

If you’re visiting Glacier National Park to see waterfalls, I recommend visiting in July when a majority of the park is accessible and the snowmelt is heavily feeding the waterfalls.

If you’re more keen to skip the crowds then visiting in the first half of September, but after Labor Day, will be the best time to visit. This is my favorite time to visit. Crowds will be minimal, most of the park is still open and the weather is reasonable. The only downside to visiting outside of peak season is limited shuttle bus and boat operation.

Are there any guided hikes in Glacier National Park? 

Yes, there are ranger-led hikes and guided tours available, which can provide additional insights into the park’s history, geology, and wildlife.

To join a guided hike in Glacier National Park stop by the visitors center. Rangers post varying guided hike schedules each week and this is the best place to learn about what’s available during your visit.

How can I stay safe while hiking in bear country? 

Hike in groups (3 or more is ideal), make noise on the trail, carry bear spray and know how to use it, and follow all park guidelines for food storage and disposal.

Overall, Glacier National Park is very safe, but it’s always important to know what’s going on around you. The visitor center has rangers on site who can provide updates on recent wildlife activity. They also have a list of trails which have been posted with a warning about bear activity or closed entirely due to frequent bears visiting the trail.

All trails will have papers posted at the trailhead to provide safety information and recent wildlife activity notices.

Can I bring my dog on the trails in Glacier National Park?

Dogs are not allowed on trails, along lake shores, in the backcountry, or in any building in Glacier National Park for safety and environmental reasons.

I was allowed to walk my dog on paved roadways, in established campgrounds and on the paved bike path that runs between Apgar Visitor Center, Apgar Campgrounds and Apgar Village. When I visit a National Park I always stop at the ranger station to ask about dog-friendly options – they have the most up to date information and sometimes they can provide helpful tips not published on their website.

Know Before You Go: Glacier National Park


Best Time To Visit: The best time to visit Glacier National Park is between July-September when the weather is favorable and the trails are open. 
Going-To-The-Sun Road, the only road that cuts through the park and connects the East and West sides, does not open until July each year. Many of the hiking trails on this list are only accessible via GTS road. 
If you’re interested in Glacier National Park waterfalls then July is the best time to visit, when snowmelt is best. 
If you’re hoping to avoid crowds I recommend going to Glacier National Park in September, after Labor Day (this is what I did).


Where To Stay: There are 13 campgrounds with over 1,000 sites to choose from within the park. Some popular ones include Apgar, Many Glacier, and St. Mary. Reservations can be made for some sites, while others are first-come, first-served.
If you prefer to stay outside of the park there are many options on the East and West sides. The West side of the park is more popular and has more options for where to stay at Glacier National Park.


How To Get There: The closest airport is Glacier Park International Airport (FCA), located in Kalispell, Montana, approximately 30 miles west of the West Entrance. However, most people fly into Missoula International Airport (MSO) to save money. MSO is approximately 150 miles south of the park.


How To Get Around: The best way to get around the park is with the free NPS shuttle service. The shuttle only runs during peak season, so if you plan to arrive before July or after Labor Day then you’ll need to bring your own vehicle. No reservations are required for the shuttle. It operates on a first-come, first-serve basis.

It’s possible to drive your own car, but you’ll need a timed-entry pass during peak season (more on this below). Driving Going To The Sun road has a vehicle limit of 21 feet long and 8 feet wide. Also keep in mind that parking in Glacier National Park can be extremely challenging year-round. Even during off-peak season I still had trouble finding parking spaces at most trailheads.


Reservation System: Between May 24 – September 8 vehicles entering Glacier National Park are required to have an advanced vehicle reservation. Reservations can be obtained through Reservation.gov up to 6 months in advance on a rolling window.


Safety: Glacier National Park is a safe park, but it has abundant wildlife, including Grizzly bears. Always hike with bear spray readily accessible, and know how to use it.


Entrance Fees: Glacier National Park entrance fees are $35 per vehicle (good for 7 days). During the winter season this pass is only $25 (Nov-Apr).
P.S There are 6 free National Park Days in 2024!
