Grottes de Cravanche

Grottes de Cravanche is a show cave in Cravanche with more than 290 meters of explorable passages spread through nine different galleries. Currently, three sections are open to visitors through guided tours that navigate the underground complex.

The cave was discovered in 1876 by workers during quarrying operations for Fort Salbert construction. These excavations revealed that Neolithic people used the site for burial practices, making it an important location for archaeological study.

The caves once served as a burial ground where people left traces of their lives thousands of years ago. Walking through the passages, visitors can imagine how Neolithic communities used this underground space for their rituals and daily activities.

The interior maintains a constant temperature around 13 degrees Celsius year-round, so warm clothing is necessary regardless of the season you visit. Tours run mainly during the warmer months and require advance booking to enter the cave.

The cave sits at the intersection where two geological formations meet: the limestone of the Jura range to the west and the gray schist of the Vosges mountains. This unusual geological meeting point created the conditions necessary for this underground system to form.
