The Grotte aux Fées ("Cave of the Fairies") in the cliffs above Saint-Maurice, Switzerland is a natural limestone solution show cave, featuring a 77-metre (253 ft) 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.
The cave was explored in 1831 when a party mapped 600 metres (2,000 ft) of passages. From 1863 Professor Chanoine Gard of the Abbey College of Saint-Maurice cleared passageways and conducted tours on behalf of an orphanage that he had founded. From 1865 the cave was operated by the Sisters of Saint-Maurice, who coined the present name. In 1925 additional exploration extended the cave network from the top of the waterfall. The network includes the 504 metres (1,654 ft) tourist gallery, the 1,200-metre (3,900 ft) Galerie des Morts and the 2,184-metre (7,165 ft) Fairies' Cave section, with an elevation difference of 122 metres (400 ft). A 2010 exploration linked the Grotte aux Fées to the nearby Grotte de Saint-Martin No.1, totaling 3,630 metres (11,910 ft) in length and 249 metres (817 ft) in elevation.
The guided tour follows a 500-metre (1,600 ft) trail, ending at the waterfall. The waterfall is fed by water from the nearby Dents du Midi peaks.
The cave was connected to Fort du Scex, which occupies the same cliff, between 1935 and 1936. The cave in turn was connected to Fort de Cindey between 1941 and 1946, forming part of the fortifications of Fortress Saint-Maurice and providing an underground connection between the two fortifications. The cave and both forts may be visited during summer months.

  • To reach the entrance to the cave you have to climb a very steep and long zig-zag path, although there are several resting places en route. The temperature in the cave is a constant 10degC, so...  more »
  • The lake and the waterfall at the end of the path are beautiful but the lake is a bit smaller than expected. The entrance fee is overpriced for the attraction if you are not a fan of geology so if...  more »
