Open Season

The lower elevation sections of Going-to-the-Sun Road remain open all year and provide access to many locations and activities. The summer opening date of the alpine portion varies from year to year, based on snowfall and plowing progress. There is no set date for the road to open over Logan Pass. Typically, the road has been fully open by early July.

Portions of the road may close due to weather. It’s typically fully open until the third Monday of October, but that may change due to weather conditions at any point.

Plowing

Plowing Going-to-the-Sun Road is a monumental challenge each year. Unpredictable spring snowstorms, avalanches, or other weather-related events can slow down progress. It’s common for work crews to need to re-plow sections of park roads when weather events happen. Safety for plowing crews, contractors, and the public is our utmost concern and priority. These unknown factors make predicting the precise opening date of Going-to-the-Sun Road impossible.

Our plowing and road status page provides information on where plows are working. You can also watch the action each spring through an annual Flickr album.
