On the Alberta side of the west block, key park features include Head of the Mountain Viewpoint, the highest point between the Rocky Mountains and Labrador, the Elkwater townsite (a cottage community sitting at the same elevation as the Banff townsite), Horseshoe Canyon and Reesor Lake viewpoints (offering 100 km views on a clear day), over 50 km of hiking and mountain biking trails, and Hidden Valley Ski Area. Three lakes sit on the Alberta side of the park (Elkwater Lake, Spruce Coulee Reservoir and Reesor Lake), with another four in Saskatchewan (Harris, Adams, Coulee Lake and Loch Leven).
