Highline Trail is a scenic route in Glacier National Park, Montana, beginning at Logan Pass and extending 7.6 miles to Granite Park Chalet, with a further 11.9 miles to Fifty Mountain Campground. Much of the trail follows the Garden Wall ridge along the Continental Divide. It is especially noted for broad views into glaciated U-shaped valleys. A 1.2-mile round-trip side trail climbs the Garden Wall to an overlook of Grinnell Glacier, adding one of the route’s notable viewpoints to an already dramatic alpine setting.
