The National Park Service will close the alpine portion of Going-to-the-Sun Road in Glacier National Park, extending from Avalanche to the Jackson Glacier Overlook, beginning at 5:00 p.m. on Sunday, September 6, 2026. The closure is a temporary measure in response to recent heavy rainfall. Hunters planning backcountry trips should avoid the affected segment and seek alternate routes or access points. Check the park’s website for updates before heading out.
