Important Travel Warnings:
In summer 2023, a vehicle reservation is required for four areas of the park: Going-to-the-Sun Road, the North Fork, Two Medicine, and Many Glacier. Each location has unique details and requires a separate reservation. Please see the Vehicle Reservation page for details.
The road is open year-round near the West Entrance. The entire road does not usually open until late June at the earliest. Please see the map above for the most up-to-date information. The alpine sections of Going-to-the-Sun Road typically close for the winter around the third Monday of October, but this can happen earlier due to wintery weather. In 2022, the road will close on September 30 at 10 pm MDT. You can find historical open and close dates on our Press Kit Page.
Specific Vehicle Size Limits
21 ft (6.4 m) long, 8 ft (2.4 m) wide, 10 ft (3 m) tall
Vehicles and vehicle combinations longer than 21 feet (including bumpers) or wider than 8 feet (including mirrors) are prohibited between Avalanche Creek and Rising Sun. Vehicles over 10 feet in height may have difficulty driving west from Logan Pass to the Loop due to rock overhangs. Stock trucks and trailers can access Packers Roost on the west and Siyeh Bend on the east.
From June 15 through Labor Day, the following sections of Going-to-the-Sun Road are closed to bicycle use between 11 am and 4 pm:
For safety reasons, 40 mph is the speed limit in the lower elevations of the road and 25 mph in the alpine section. Please be careful around blind curves, as animals and pedestrians often cross the road unexpectedly.

The park’s shuttle service is a point-to-point transportation service only, not a narrated tour. The Going-to-the-Sun Road audio tour has information about each shuttle stop.
Glacier National Park Lodges may offer a seasonal shuttle for a fee that connects to St. Mary and Many Glacier.
Times listed below are estimates and will vary based on road construction, traffic, and time of day.
