Glacier National Park Tourist Trails--Inside Trail, South Circle, North Circle

The Glacier National Park Tourist Trails, including the Inside Trail, South Circle Trail and North Circle Trail, were established in Glacier National Park to connect a series of tourist camps and hotels established by the Great Northern Railway between 1910 and 1915. Prior to the construction of the Going-to-the-Sun Road, these trails were the primary form of circulation within the park. The trail system includes a number of bridges. The three separate trail systems link Many Glacier, Two Medicine, Cut Bank, Saint Mary and Goathaunt ranger stations and visitor centers. Sites associated with the trail system include the Gunsight Pass Shelter, Packer's Roost, Pass Creek Snowshoe Cabin, Granite Park Chalet and the Ptarmigan Tunnel.
