What August is like in Glacier National Park

August is warm and dry, with highs near 78F (26C) and the most snow-free trails of the year. Nearly every hike is open, from Grinnell Glacier to Iceberg Lake, and huckleberries are ripe. Crowds and prices stay at their peak, and some years wildfire smoke drifts in and hazes the views for days at a time.

August suits hikers who want the widest choice of trails and families on summer break. It is the safest bet for reaching the high country. If smoke would ruin the trip for you, or you want fewer people, consider mid September instead. Either way, keep a flexible day in your plans in case of smoke or trail closures.

Make the most of August

What is especially good about Glacier National Park this month.

The most open trails of the year

Late snowfields are mostly gone, so long hikes like Grinnell Glacier and the full Highline are at their most reliable.

Huckleberry season

Berries are ripe along trails and in every bakery nearby. Bears are feeding hard too, so talk and clap as you hike.

Late wildflowers

Higher meadows still hold blooms into August, especially around Logan Pass.

What to pack for August

Bear spray, carried on your hip, not in your pack
A lightweight sun hoodie for long exposed hikes
An N95 mask in case wildfire smoke settles in
Trekking poles for the long descents on Grinnell and the Highline
Plenty of water, since afternoons are hot and dry

Our timing tip

Check air quality and trail status each morning, and start big hikes by 7am to beat both the heat and the parking crunch at Many Glacier.

Usually snow-free and fully open from mid July. Airy ledges, huge views, and mountain goats; arrange a shuttle for the one-way hike.

Tickets and tours →

Many Glacier and Grinnell Glacier Trail

The best hiking hub in the park, with moose, bears, and a glacier at the end of the trail. Parking fills early.

Tickets and tours →

Tickets and tours →

Tickets and tours →

Beat the crowds

Start early. Logan Pass parking fills quickly in summer, and 2026 added time-limited parking there; being on the road by 7am makes the day easier.
Base yourself on the east side at St. Mary or Many Glacier for quieter lodging and faster access to the best hikes.
Visit the second or third week of September for open roads, cooler weather, and far fewer people, accepting that some services close.
Explore Two Medicine or the North Fork when Going-to-the-Sun Road and Many Glacier are at their busiest.

Know before you go

Going-to-the-Sun Road's alpine section typically opens fully between late June and mid July and closes around the third Monday of October; the lower ends near Lake McDonald and St. Mary stay open longer. Snow can delay or shorten the season.
Vehicle reservation systems have changed year to year: required in recent summers, not required in 2026, when the park piloted a ticketed shuttle and time-limited Logan Pass parking. Check the park's current rules before planning.
In-park lodges, restaurants, and most campgrounds are seasonal, generally open from about late May or June to mid or late September. Many Glacier Hotel and others close before the road does.
Several trails close temporarily for bear activity at any time. Carry bear spray and check trail status daily.
