At Mortain, the waters of the Cance River and Cançon River cascade down in two magnificent waterfalls. This grandiose natural site in the depths of Armorican Normandy can be reached via numerous trails. After a walk through green undergrowth, you reach a small rocky cirque where water rushes down the Petite Cascade from a height of 35m, and then the Grande Cascade, which crashes down from 25m.
