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

The best time to visit Glacier National Park depends on your preferences and what activities you have in mind. Here are some key considerations for each season:

Summer (July to September)

• This is the peak tourist season, with warm but comfortable temperatures, ranging from 60º to 70º F, and occasional hot days up to 90º F23.
• The Going-to-the-Sun Road is fully open, and all hiking trails are snow-free, making it ideal for hiking, driving, and exploring the park13.
• However, it is the busiest time, with crowded trails, parking lots, and campsites1.

Fall (September to October)

• This period is often recommended for those who want to avoid the crowds but still enjoy good weather. The temperatures are cooler, but still pleasant, and the foliage is vibrant, especially the golden larches in late September to mid-October34.
• The Going-to-the-Sun Road is mostly open, and wildlife is easier to spot during the rutting season34.

Spring (April to June)

• Spring is the quietest season, with fewer visitors. While the higher elevation trails are still snowy, lower elevation trails start to clear by mid-April15.
• This season offers powerful waterfalls due to snowmelt and is a good time for cycling on the Going-to-the-Sun Road before it opens to cars14.

Winter (November to April)

• Winters are long and snowy, with significant snowfall, especially at higher elevations. However, the park can be mild due to Chinook winds, and temperatures can sometimes rise to 50º F25.
• This season is best for those interested in winter sports and a serene, snow-covered landscape, but many facilities and roads are closed.

Recommended Times

• For optimal weather and full access to trails and roads, July to September is the best time, but it is also the busiest13.
• For a balance between good weather and fewer crowds, September after Labor Day is highly recommended34.

Ultimately, the best time to visit Glacier National Park depends on whether you prioritize warm weather and full access to trails, or prefer fewer crowds and unique seasonal experiences.
