Some backcountry travel restrictions at Glacier National Park were lifted Tuesday/NPS file

Two days after some backcountry closures were instituted at Glacier National Park due to grizzly bear activity, the park on Tuesday lifted some of those closures.

Sunday evening park staff closed the Highline and Loop trails and Swiftcurrent Pass area, from Swiftcurrent Pass to Granite Park Chalet, meaning that access to the Granite Park area was not possible. Additionally, the Granite Park backcountry campground was closed to campers arriving Monday.

Following a day of patrol Monday, and a night of observations, no further bear sightings were reported.

On Tuesday, the park reopened the Highline, Loop, and the closed portion of the Swiftcurrent Pass Trail.  However, the Granite Park backcountry campground remained closed.

The trails remain posted for "bear frequenting," meaning that recent repeated observations or confirmed reports of bear sign in short intervals exist in those areas. Visitors should exercise heightened situational awareness and watch for signs of bears on trails posted for bear frequenting.

Glacier is bear country and hikers should be prepared to encounter bears on trail at any time. Hikers should always carry bear spray, have it easily accessible on a hip or chest harness, and be comfortable using it.
