Patricia Lake in Jasper National Park, Alberta, is smaller than its neighbour, Pyramid Lake, but is twice as deep at 40m (131 feet). There is a 4.8 km (3 mile) trail around the lake. Boat, bicycle and fishing rentals are available at Patricia Lake Bungalows.
Numerous lakes and streams teem with fish. Rocky Mountain whitefish and seven species of trout, including brook, brown, bull, cutthroat, lake and rainbow can be found here.
