Sun road & glacial valleys

Glacier National Park, MT

One road over the divide, and valleys on either side that feel like different parks.

Best time to visit

July to September

The only window when Going-to-the-Sun Road is open over the pass and both sides of the park are reachable. Either side of it, the park is two dead-end valleys.

Know before you go

Glacier is bisected by the Continental Divide, creating two distinct worlds in one park: temperate rain-forest valleys on the west and windswept, dramatic limestone crags on the east. The high-altitude Going-to-the-Sun Road connects the two, serving as one of the most engineered, jaw-dropping mountain passes in North America. It is raw, remote wilderness that rewards early risers and prepared hikers.

Getting around

A car is practically mandatory to reach disjointed valleys like Many Glacier and Two Medicine. A park shuttle runs the Going-to-the-Sun Road corridor in peak season, but parking lots at major trailheads still require early arrivals.

Local tips
  • Start your hikes before sunrise to secure parking at Logan Pass and Avalanche Lake, and to catch active wildlife.
  • The Continental Divide creates its own weather—always pack a windbreaker and fleece, even on sunny midsummer mornings.
  • Drive Going-to-the-Sun Road in both directions if time allows; the vistas open up completely differently heading east versus west.
  • Hike beyond the first two miles of any popular trail to instantly leave behind the majority of tour-bus crowds.

Neighborhoods to know

The dramatic hiking core of the park, packed with sheer cirques, active glaciers, and high grizzly activity.

Logan Pass & St. Mary

Windswept alpine tundra along the Continental Divide that transitions into open prairie on the eastern boundary.

Two Medicine

A quieter, less-developed southeastern basin with sacred Blackfeet heritage, striking dark peaks, and fewer crowds.

Frequently asked

When is the best time to visit?

July through September offers the most reliable window for an open Going-to-the-Sun Road and snow-free high-elevation trails.

Do I really need bear spray?

Yes. Glacier has one of the densest grizzly populations in the lower 48. Keep it on your hip or chest where you can draw it in seconds, not buried in your pack.

Is it better to stay on the east or west side?

Split your time if you can. The west side offers denser amenities and lush forests, but the east side puts you right at the door of the park’s most dramatic alpine hiking.

Can I get by without a car?

Technically possible via the Sun Road shuttle, but very limiting. You need a car to reach trailheads in Many Glacier, Two Medicine, and the North Fork.
