BANFF Banff National Park, in south-western Alberta, Canada, formally established in 1885. Located on the eastern slopes of the Rocky Mountains, it is famous for its spectacular mountain scenery. Banff National Park is Canada's oldest national park. It originally comprised an area 26 sq km (10 sq mi) in extent, around hot springs that had been discovered in 1883. Countering a plan for the purchase and commercial exploitation of these hot springs, the Canadian government declared the area a public land reserve. In 1887, the park was expanded to take in a total area of 6,640 sq km (2,564 sq mi). As well as hot springs the park contains waterfalls, densely forested valleys, alpine meadows, glaciers, and many glacial lakes, including Lake Louise. The park's abundant wildlife includes puma, black and grizzly bears, elk, moose, bighorn sheep, and mountain goat. There are 20 camping sites and 1,300 km (over 800 mi) of hiking routes and trails, which can be used for cross-country skiing in winter. Canoeing and water sports are also popular leisure activities. However, the large numbers of visitors that the park attracts make it difficult to maintain as a conservation area.
