Glacier National Park is open year round and the best time to visit Glacier depends on your interests.

What Season is the Best Time to Visit Glacier National Park? We Break It Down

Trying to figure out the best time to go to Glacier National Park? You’ve come to the right place. Since we live in Montana, we know the ins and outs of this popular national park and why it’s great at any time of year. But…

There’s a big ‘but’ for picking the best time to visit Glacier National Park, and that is if you’re planning a once in a lifetime trip to Glacier National Park, or you simply want to have access to as much of the park as possible. If so, then you’re going to want to carefully pick the month you go. 

Glacier Park is Partially Closed in Winter 

The reason you’re going to want to pick the right month to visit is because Glacier National Park is mostly closed down in the winter. You might be thinking, great I’ll just be sure to go in spring or summer then! But hold up, adventurer: Even in early and late summer, parts of the park can be closed to visitors if late snow removal or early snowfall has made the roads inaccessible. 

(But don’t worry, if you only can make it to western Montana in the winter months and are set on experiencing the wonders of Glacier National Park, we have some tips for you below. First though, let’s talk about the high season: summer.)

Glacier National Park in Summer

Summer is easily one of the best times to visit Glacier National Park.

While weather is unpredictable, if you stick to the summertime days before Labor Day, you’re likely to have good enough weather that you don’t have to worry about too much of the park being closed, which is what makes summer the best time to visit Glacier National Park for most people. 

Mentality Tip: There’s always a chance parts of Glacier National Park might be closed due to weather, fires, wildlife protection, etc. After all, it’s the open wild — things happen. So go with an open mind and embrace the parts of the park you see and don’t dwell on what you can’t see. 

While visiting Glacier National Park in July and August means you’ll most likely be privy to warm weather, sunshine, and a wide open park, there is a trade-off: crowds. 

It’s hard to avoid crowds in Glacier if traveling there during the high season. It might be the best time to visit, but you’ll have to be patient and expect some traffic delays and crowds at prime viewing spots. 

The Pitamakan Loop Hike is one of the most beautiful hikes in Glacier National Park.

If warm weather appeals to you, but crowds don’t, embrace your inner mountainman or mountainwoman and plan on doing some of the longer, more off-the-beaten-path hikes, such as Pitamakan Loop. Just do your research beforehand and be prepared with layers, water, and bear spray). 

What to Pack When Going to Glacier National Park in Summer

Even in summer, the temperature can dramatically change throughout the day and in different parts of the park. Elevation levels can greatly affect how warm or cold it is, too. Therefore, it’s smart to wear layers, like these:

A comfortable hiking pack to put discarded layers into is also a must.

Spring in Glacier National Park

Pretty wildflowers during springtime around Glacier National Park.

First off, at Glacier it’s still pretty much winter in April, when most of the rest of the country is shifting into spring. But not in the mountains! In Glacier National Park, the spring season typically starts in the beginning of May when more of the snow has melted and goes through mid-June. 

The famous Going-to-the-Sun road isn’t open to vehicles in Spring and other parts of the park might also be closed; however, this can still be the best time to go to Glacier National Park for those who appreciate fewer crowds, burgeoning flora and fauna, and biking.

Spring shoulder season means fewer people — shoulder season is the term given to the times of year right outside of the high season for a destination; typically when kids are still in school or the weather isn’t quite ideal yet. 

Fewer crowds mean Spring in Glacier National Park is a great time to go to the park to improve your chances of seeing wildlife. Since the trails and roads aren’t as clogged with people and cars, the animals get closer to trails and roads to forage for food.

Speaking of cars, the main roads in Glacier National Park don’t open to vehicles yet in the Springtime months, but you can ride a bicycle along many miles of those roads during spring season. If you love biking, this is an incredible way to see the park as you have the roads to yourself and can navigate the terrain at a more leisurely pace.

Autumn in Glacier National Park

Gorgeous fall colors at Glacier National Park.

On the other side of shoulder season is autumn in Glacier. Winter comes swiftly in the mountains of Montana and for that reason, most of the Going-to-the-Sun road usually closes to cars in early to mid October, well before most people think of winter arriving. But as mentioned previously, if snowfall or freezing temperatures happens earlier in the season, it can result in roads and other amenities in the park suddenly shutting down, so going to Glacier National Park in autumn can be a gamble. 

However, if you don’t mind the chance of the major road through the park being closed, going to Glacier National Park in autumn can have a great reward of nice weather, access to most of the park, and — most importantly for those who prefer traveling in shoulder season — fewer crowds. 

Ultimately, thinking of autumn as the best time to go to Glacier National Park is ideal for those who can be flexible in their travel plans, don’t mind inclement weather, and prefer fewer people over convenient access to amenities and facilities in the park — and want the wonderful reward of seeing some of the most beautiful fall foliage in the west.
