The Front Ranges are located east of the Main Ranges. Banff National Park extends eastward from the continental divide and includes the eastern slope of the Main Ranges and much of the Front Ranges. The latter include the mountains around the Banff townsite. The foothills are located to the east of the Park, between Calgary and Canmore. On the other side of the Park, the Western Ranges pass through Yoho and Kootenay National Parks. Still farther west is the Rocky Mountain Trench, the western boundary of the Canadian Rockies region in British Columbia.
