Discover the Perfect Time for Your Glacier National Park Adventure

Glacier National Park is a true wonderland of pristine forests, jagged mountain peaks, and glacial-carved valleys. But with such dramatic seasonal changes, deciding when to visit can make or break your park experience. Never fear, this handy guide covers the pros and cons of each season so you can plan the ideal Glacier getaway!

Summer Splendor: The Prime Park Season

Summer is the most popular (and crowded) time to visit Glacier. And for good reason! The months of July and August offer the warmest and sunniest weather, with temperatures ranging from the 40s at night up to around 80°F during the day.

All of the main roads, visitor centers, lodges, and over 700 miles of hiking trails are fully open and accessible during these peak months. You'll be able to take the famous Going-to-the-Sun Road for jaw-dropping mountain vistas. Just be prepared for big crowds and pricey lodging if visiting in July or August.

If wildflowers are your thing, this is primetime! The meadows burst into a rainbow of blooms in mid-summer. It's also prime time for spotting wildlife like bighorn sheep, mountain goats, and the iconic grizzly bears.

Fewer Crowds in Spring and Fall

Looking to avoid the peak season madness? Late spring (May-June) and early fall (September-October) offer lighter crowds and potentially better lodging deals. The downside is some visitor facilities and higher elevation roads may still be shuttered or closing for winter.

In May, there's still a lot of snow covering the higher trails, but the milder temps and emerging wildflowers make hiking at lower elevations a real treat. By late September, the fall foliage paints the park in stunning shades of red, orange, and gold.

Wildlife watching can also be incredible in these "shoulder seasons" as charismatic megafauna are more active. Just be sure to check park conditions before you go as weather can be unpredictable in spring and fall.

See the Magical Northern Lights in Winter

If catching a glimpse of the mystical aurora borealis is on your bucket list, winter is the best time for northern lights viewing at Glacier. From around December through March, the long hours of darkness give you a better chance of spotting this dazzling celestial lightshow.

Some favorite spots for aurora viewing are lakeshores like Lake McDonald, Bowman and Kintla Lakes, and the road at Looking Glass Hill. Just bundle up and prepare for freezing temps and limited park access with many seasonal and high elevation road closures.

What to Know Before You Go

No matter when you decide to visit Glacier National Park, advance planning is essential. The extremely popular Going-to-the-Sun Road typically opens in late June/early July and closes in October due to heavy winter snowfall.

If hiking is your aim, secure permitting well ahead of time as limits are in place for many of the park's prime backpacking routes. And be sure to secure lodging reservations months in advance for summer visits.

The park's free shuttle system runs during peak season, which can help you avoid parking headaches. But the shuttle has limited service in spring and fall, so you may need to snag a coveted parking spot early.

For the most up-to-date info on road openings, trail statuses, and other conditions, check the National Park Service website or inquire at one of the park's visitor centers.

FAQs on the Best Time to Visit Glacier
