What’s Open in Glacier National Park in August?
August is peak season at Glacier National Park – everything is open and accessible.
Here’s what you can expect in August:

Going‑to‑the‑Sun Road
By August, all major park roads are open. The Going-to-the-Sun Road is fully open and the highlight of any visit.
Traffic and parking can be challenging, especially along Going-to-the-Sun Road. Consider using the park shuttle system or arriving early to secure parking.

There are two main trailheads at Logan Pass – the Hidden Lake Overlook and Hidden Lake trails are accessible and the iconic Highline Trail is also typically open, including the side trail to Grinnell Glacier Overlook.

Is August a Good Time to Visit Glacier National Park?
Yes. August is one of the best months to visit Glacier National Park. With full access, incredible hiking, and vibrant alpine scenery, it offers the ultimate Glacier experience. One main advantage to visiting in August, rather than July is that all the snow on the trails should have cleared, meaning you can explore further later in the summer.
However, this is of course the park’s busiest period. So, plan ahead, start early, and be prepared for crowds to make the most of your visit.
Pros
- The driest month of the year
- Hiking trails should now be free from snow, so the best month for the higher altitude trail
- You can make full use of shuttles, campgrounds, local facilities and the Going-to-the-Sun road
- Peak wildflower season
- Full access to all roads and trails
Cons
- Summer is peak tourist season, so expect crowds
- Reservations are needed for the shuttle
- There’s a time limit on parking at Logan Pass
- Afternoon thunderstorms are possible
