Glacier National Park Tourist Trails

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.
