Banff, AB Factoid
Located some 20 kilometers from the nearest road, Castleguard Caves, Canada's longest cave system, is situated just northwest of Banff. The 16-kilometer long cave is also Canada's second deepest. Unfortunately, the cave isn't open to the public due to unpredictable flooding in the spring and summer months – only specially approved expeditions are permitted, and only in the winter.
