Waterton Lakes National Park is a national park located in the southwest corner of Alberta, Canada, and borders Glacier National Park in Montana, United States. Waterton was Canada's fourth national park, formed in 1895 and named after Waterton Lake, in turn after the Victorian naturalist and conservationist Charles Waterton. The park contains 505 km² (195 sq mi) of rugged mountains and wilderness.
Operated by Parks Canada, Waterton is open all year, but the main tourist season is during July and August. The only commercial facilities available within the park are located at the Waterton Park townsite. The park ranges in elevation from 1,290 metres (4,232 ft) at the townsite to 2,910 m (9,547 ft) at Mount Blakiston. It offers many scenic trails, including Crypt Lake trail.
