Drive Going-to-the-Sun Road

Car drives uphill over triple arched stone bridge


Driving Going-to-the-Sun Road can take just a few hours, or you might spend all day enjoying the views. For safety reasons, 45 miles per hour is the speed limit in the lower elevations of the road and 25 miles per hour in the alpine section.

Scenic Driving

Pets are allowed in developed areas (e.g. parking lots, along roads) but are not allowed on trails. Pets must be on a leash no longer than 6 feet (1.8 m), under physical restraint, or caged at all times, including while in open-bed pickup trucks.

No additional fee

No reservations are needed for personal vehicles or for taking the park shuttle. Reservations are recommended for bus tours.


Though portions of Going-to-the-Sun Road remain open year round, seasonal conditions (snow!) mean a drive across the whole road is only possible during summer months. Check Glacier’s Road Status page before your trip.

We suggest arriving early or staying late if you want to find parking at Logan Pass. Be extremely cautious driving at night; visibility is low and wildlife may be numerous.

A trip across Going-to-the-Sun Road is a trip into the heart of Glacier. This “transmountain highway” offers exceptional views at every turn. The road stretches about 50 miles between the West Entrance and St. Mary Entrance, and climbs to 6,466 ft (2,025 m) at Logan Pass. There are numerous stopping points along the road. Highlights include Lake McDonald Lodge, short hikes like Trail of the Cedars or St. Mary Falls, Logan Pass Visitor Center, and the many informative wayside signs that explain features and track your journey.

There are multiple ways to travel:

  • Drive a personal vehicle. Be aware there are size restrictions. Vehicles, and vehicle combinations, longer than 21 feet (including bumpers) or wider than 8 feet (including mirrors), are prohibited between Avalanche Campground and the Rising Sun picnic area parking.
  • Take the free Glacier Shuttle System that runs two-way service between Apgar Visitor Center and St. Mary Visitor Center.
  • Book a tour with commentary with either park concessionaire, Sun Tours or historic Red Buses.

Explore the Going-to-the-Sun Road pages on Glacier's website for further information about the shuttle, audio tours, road status, and more.
