William A. Switzer Provincial Park is a provincial park in Alberta, Canada. It is located on both sides of the Bighorn Highway, between Grande Cache and Hinton. The park is situated in the Canadian Rockies foothills, at an elevation of 1,150 m (3,773 ft) to 1,300 m (4,265 ft) and has a surface of 93 km2 (35.9 sq mi).
William A. Switzer Provincial Park was originally called Entrance Provincial Park after the town located at the railway entrance to Jasper National Park. It was renamed in 1974 to honour the first mayor of Hinton. The park is located in a beautiful foothills setting with lodgepole pine, spruce & aspen forests. The area, once known as Fish Lakes Valley, features a chain of five lakes that are popular for fishing, boating, canoeing, and swimming.
Various campgrounds are maintained on the shores of Gregg Lake, Cache Lake, Blue Lake and Jarvis Lake.
