Everyone should experience the grandeur of Glacier National Park in northern Montana at least once in their life. The rugged Rocky Mountain peaks, the glistening alpine lakes, and the enormous landscapes stand out like no other wild places in the country. The park is aptly dubbed the Crown of the Continent, and the best time to experience Glacier is as soon as you can.

For a vast majority of visitors, the best time to visit Glacier National Park is during the summer season between mid-June and late September. The months of July and August in particular are a great time to visit. The iconic Going-to-the-Sun Road that spans the entire park is snow-free during these summer months, and other high-mountain hiking trails are accessible throughout the season. The summer season does come with some crowds, but there's plenty of scenery to share in the 1,500-square-mile national park.

The shoulder seasons are also great times to travel to Glacier to avoid the worst of the crowds. The Going-to-the-Sun Road typically remains open until the third Monday of October and has less traffic to contend with during the fall. The road doesn't reopen until late June and sometimes early July, but the east and west sides of the park are both accessible in the spring.

The snow-free months between mid-June and late September are the best time to travel to Glacier National Park. Logan Pass and other iconic park attractions like the Going-to-the-Sun Road are fully accessible in the summer. And other park amenities like lodging and visitor centers are also fully operational throughout the season.

Summer temperatures reach into the 80s during the day and remain above freezing throughout the night. Boat tours and restaurants are also fully operational during July and August.

The summer brings vibrant color to the park with wildflowers like bear grass at full bloom. And the full range of wildlife in Glacier is often seen in the summer including elk, bighorn sheep, moose, and the occasional black or grizzly bear.

The summer also brings big crowds to places like Logan Pass, Lake McDonald, and Many Glacier. Approximately two-thirds of the park's roughly three million visitors each year come during the summer. July and August are the peak season for visiting Glacier National Park. The park has hosted over 1.5 million visitors between these two months every year for the last five years.

These crowded conditions make logistics like parking and lodging something to plan for in the summer. Visitors will want to make reservations ahead of time for summer visits. The park's free Going-to-the-Sun Road Shuttle can help reduce some driving concerns.

With fewer crowds, the shoulder seasons are also great times to go to Glacier. Visitors in the spring and fall enjoy the changing colors of the season but may not be able to access all the park's facilities. Glacier's typical full operating season extends from Memorial Day to Labor Day. Variable conditions, including rain and snow, exist throughout the shoulder seasons, and the west side of Glacier usually receives more rainfall than the east.

Things to do at Glacier National Park change with the seasons. Places to stay also fluctuate with the changing temperatures. Each season also brings its own challenges, like crowds in the summer and variable road conditions throughout the rest of the year. With the right preparation and planning, though, every season in Glacier offers reasons to visit.

Spring: Spring in Glacier typically begins in May and extends through mid-June and early July in the highest regions of the park. Alongside fewer crowds to contend with, wildflowers start to give Glacier some color later in the season, and many of the park's waterfalls are at their highest flow during the spring. Wildlife in the park also tends to become more active as things start to warm up.

Spring is a good time to visit for fewer crowds, but many facilities, including the Going-to-the-Sun Road, don't open until late June at the earliest. Campgrounds and other facilities like restaurants and lodging also don't generally open until Memorial Day Weekend.

Summer (Best Time to Visit): Glacier National Park is in full operation during the summer, particularly in July and August. Summer is the peak visiting season in Glacier. Popular activities in the summer include camping, backpacking, day hiking, fishing, and boating. Cooler temperatures in the evening also allows guests to enjoy Glacier's starry night sky. The free Going-to-the-Sun Road shuttle operates on a full-time schedule in the summer.

Winter in Glacier National Park

Fall: Fall brings variable weather throughout the region, but Glacier National Park in September is a particularly good time to visit. Crowds typically diminish after Labor Day, and daytime highs stick around the 60s and 50s throughout the season. Autumn is quite colorful in Glacier, particularly between late September and mid-October when golden larches dot the mountainsides. Many of the park's iconic hiking trails also have fewer crowds this time of year.

Several of the park's facilities close during the fall, with resources like lodging and restaurants becoming less available throughout the season. Many campgrounds within the park also close in September, except St. Mary and Apgar Campground, which operate year-round. The Going-to-the-Sun Road typically becomes impassable by the third Monday in October.

Winter: Encompassing both sides of the Continental Divide, winter weather in Glacier National Park is variable from one region to the other. Glacier in November and December features road closures, avalanche conditions, and cold temperatures throughout the park. Despite the difficulties, winter in Glacier has many rewards that make it worth a visit.

While few facilities are open within the park during the winter, the surrounding communities are often happy to host visitors with reduced overnight rates. Free winter camping in Glacier is available at the St. Mary Campground and Apgar Campground for those equipped to handle the conditions. Popular activities for winter visitors include cross-country skiing and snowshoeing.

While the summer months of July and August provide spectacular conditions throughout the park, this peak visiting season also produces quite the crowds. Parking at Logan's Pass is a genuine challenge in the summer, and popular hiking trails like the Highline Trail become inundated with foot traffic.

For those looking to avoid the summer traffic completely, the winter is the best season to go to Glacier National Park to avoid crowds.With cold temperatures and sudden road closures deterring other guests, winter visitors almost have Glacier to themselves.

For warmer weather, the fall is an easier time to travel to Glacier while still avoiding the worst of the crowds. Crowds tend to thin out after Labor Day in Glacier National Park, and visitors can expect cool but pleasurable temperatures through October.

Spring is also a good time to travel to Glacier to avoid the biggest crowds. Variable snow and rain conditions linger throughout May and into June, which makes planning a long-distance trip harder to time. Visitors can bike the Going-to-the-Sun Road with no vehicles on the road until late June as snowplows work their way up the road.

The best way to avoid summer crowds in Glacier National Park is to arrive before 7am at the trailhead or parking area. For extremely popular areas like Logan Pass, 7am might not be early enough to find a parking spot. Starting activities in the late afternoon (after 4pm) can also avoid the rush of daytime visitors.

The bulk of visitors to Glacier spend most of their time on the Going-to-the-Sun Road. To avoid this traffic, consider exploring other equally gorgeous areas of the park. On the east side, the Many Glacier and Two Medicine regions offer alternative landscapes to explore. On the west, the North Fork area, including Bowman Lake, is another option away from the main tourist route.

Spots like Hidden Lake near Logan Pass offer much more accessibility in the shoulder seasons.
