Cuves de Sassenage, Natural show cave in Sassenage, France.
Cuves de Sassenage is a natural cave system shaped by the Germe River, featuring about 200 meters of accessible passages where visitors walk through narrow paths and chambers. The underground galleries reveal different rock formations created over thousands of years.
Scientific exploration of the cave began in the 17th century, and the system opened to visitors in 1947. The original development created the route that visitors still follow today.
The cave system tells the story of Melusine, a mythical figure from local folklore said to inhabit these underground passages. Visitors encounter this legend through atmospheric presentations during their visit.
The cave remains cool throughout the year, so bringing warm layers is a good idea even in summer. The paths can be slippery, and sturdy shoes help visitors navigate the narrow passages safely.
The cave system connects underground to Gouffre Berger, another major cave system in the region, proven through scientific dye tracing studies. This hidden link reveals how water flows beneath the surface, linking different caves together.
