Crypt Falls is a waterfall in Waterton Lakes National Park in southwestern Alberta, Canada, where water flows out of Crypt Lake and descends toward a smaller lake below. Visible from the Crypt Lake Trail, a route commonly accessed by ferry from the Waterton townsite, the falls form part of the dramatic mountain scenery on the way to Crypt Lake. Although a published height has been given, the waterfall’s exact drop is not known, and the true height is believed to be greater than the listed figure.
