Month by month
Glacier by season
Winter Poor
Deep snow. Only the lower ends of the park are reachable, for cross-country skiing and snowshoeing near Lake McDonald.
Spring Poor
Plows clear the Going-to-the-Sun Road through May and June. Bike the closed road before it opens to cars.
Summer Prime
The short main season. The Going-to-the-Sun Road usually opens fully in late June or early July, and wildflowers peak in July. Wildfire smoke is possible in August.
Fall Fair
September is superb: fewer people, larches and aspens turning, and the road open until mid-October.
What to do
- Drive the Going-to-the-Sun Road over Logan Pass
- Hike the Highline Trail
- Hike to Grinnell Glacier
- Explore Many Glacier for wildlife
- Paddle Lake McDonald or Two Medicine Lake
Many Glacier is the best area for grizzlies, moose and bighorn sheep. Go early in the morning for both wildlife and parking.
