Cuves de Sassenage

The cave system features underground passages formed by the Germe River, revealing various geological formations through narrow paths and galleries.

Scientific explorations of the cave system began in the 17th century, leading to its public opening in 1947 with 200 meters of developed passages.

The cave holds the legend of Melusine, a mythical figure whose story is presented through light shows during guided tours.

Tours operate from June to October with specific time slots, offering adult tickets at 8 euros and children tickets at 5 euros.

The cave system connects hydrologically to the Gouffre Berger through underground water networks, confirmed by scientific dye tracing studies.
