Prince Albert National Park encompasses 3,874 square kilometres (1,496 sq mi) in central Saskatchewan, Canada and is about 200 kilometres (120 mi) north of Saskatoon. Though declared a national park March 24, 1927, official opening ceremonies weren't performed by Prime Minister William Lyon Mackenzie King until August 10, 1928. This park is open all year but the most visited period is from May to September. Although named for the city of Prince Albert, the park's main entrance is actually 80 kilometres (50 mi) north of that city via Highways 2 and 263, which enters the park at its southeast corner. Two additional secondary highways enter the park, Highway 264, which branches off Highway 2 just east of the Waskesiu townsite, and Highway 240, which enters the park from the south and links with 263 just outside the entry fee-collection gates. Prince Albert National Park is not located within any rural municipality, and is politically separate from the adjacent Northern Saskatchewan Administration District (NSAD). Until the establishment of Grasslands National Park in 1981, it was the province's only national park.
