Glacier National Park Announces Multiple Temporary Closures Due to Flooding

WEST GLACIER, Mont. [ June 29, 2026] - Heavy rainfall has caused significant flooding across Glacier National Park, prompting multiple temporary closures. Rising water levels and unstable ground conditions are affecting roads, trails, and infrastructure.

The entire Many Glacier Valley, including Many Glacier Hotel, Swiftcurrent Motor Inn, and the Many Glacier Campground is closed to the public to ensure visitor safety during ongoing flooding in the area. The Many Glacier Hotel and Swiftcurrent Motor Inn have been evacuated due to flooding. All trails in the Many Glacier Valley are closed until further notice.

Commercial boat tours operated by the Glacier Park Boat Company and horseback rides operated by the Swan Mountain Outfitters in Many Glacier have been suspended for the duration of the closure.

Glacier National Park will work closely with the Federal Highway Administration when it is time to reopen the Many Glacier Valley to ensure that access is restored safely.

Heavy rainfall has also impacted access along Going-to-the-Sun Road. A temporary closure was implemented on June 28 from Avalanche to Jackson Glacier Overlook. With the increase in water and debris along the road, closure points have been adjusted, the west side closure remains at Avalanche, and the east side closure has moved to Rising Sun. Visitors should expect detours, delays, and limited access while crews respond to hazardous conditions created by fast-moving water, debris, and saturated soils.

There is no hiker/biker access past any road closures, and all closure points should be avoided.

The park urges visitors to practice responsible visitation during this weather event. Flooded areas should never be crossed, and all posted closures must be followed. Travelers should check current conditions before arriving and remain flexible with plans as weather and access may change quickly.

The National Weather Service issued a Prolonged Rain and Runoff warning from Sunday, June 28-Tuesday, June 30. Heavy rain in steep terrain may lead to possible rockslides, and rapid water rises from small streams.

Glacier National Park will evaluate and re-open areas when conditions improve.

Visitors are reminded that weather conditions can change quickly, and park travelers should always be prepared for inclement weather. Check the park website for the most up to date information.
