Grotte aux Fées, Saint-Maurice

The Grotte aux Fées in the cliffs above Saint-Maurice, Switzerland is a natural limestone solution show cave, featuring a 77-metre high underground waterfall, claimed as the world's highest waterfall in a show cave. The cave was the first show cave in Switzerland. The cave was known until the mid 19th century as the Trou aux Fayes or "Sheep Hole," as it was used as a sheepfold. The cave was known from Roman times, but was first publicized in 1863 as a tourist attraction, with the present name being used from 1865. ()
