Glacier National Park‘s Going-to-the-Sun Road is scheduled to open to motorized vehicles tomorrow, Monday, June 22nd, marking the official start of the 2026 summer driving season on one of the most iconic roads in North America.
The 50-mile transmountain highway stretches from the West Entrance to the St. Mary Entrance, climbing to 6,646 feet at Logan Pass. Park officials caution that rockfalls or other natural events could delay the opening, as alpine conditions along the corridor can change rapidly.
Sunday, June 21st is the final day of a cyclist-only window that began June 18th. Riders still hoping to experience the road without vehicle traffic have one last chance today before motorized access begins tomorrow morning.
Once the road opens to vehicles, drivers should be aware of size restrictions. Vehicles and vehicle combinations longer than 21 feet or wider than 8 feet are prohibited between Avalanche Campground and the Rising Sun picnic area parking lot. The speed limit drops to 25 miles per hour in the alpine section of the road. Vehicle reservations may be required for personal vehicles and motorcycles during certain times. Visitors should check the park’s vehicle reservations page before heading out.
The Logan Pass Visitor Center reopens to the public on June 22nd, along with the Glacier National Park Conservancy bookstore. Restrooms at the visitor center have been open throughout the cyclist window.
Visitors who prefer not to drive can access the road via the free Glacier Shuttle System, which runs two-way service between Apgar Visitor Center and St. Mary Visitor Center, or through guided bus tours offered by Sun Tours and the historic Red Bus concessionaire.
Road status updates are available on the National Park Service website at nps.gov/glac.
