Höllgrotten, Baar-Zug, CH

The Höllgrotten caves lie in the midst of the wild and romantic Lorze ravine near Baar, in the canton of Zug. Discovered in the second half of the 19th century, they are among the most fascinating stalactite caves in Switzerland. Little pools and stalagmites and stalactites in various colour nuances characterise each cave. The 45-minute tour through the illuminated, 10°C-underworld can be undertaken independently.
