Grotte de la Luire

Grotte de la Luire is a cave in the Vercors massif featuring a prominent natural entrance and an extensive network of underground passages. The site functions as both a natural wonder and a space where visitors can explore developed sections of this subterranean system.

During World War II in 1944, the cave served as an emergency shelter and hospital for French Resistance fighters following intense German operations in the area. This period marks an important chapter in the site's history beyond its geological significance.

The name comes from local folklore about a water spirit said to dwell in the underground passages and control the flow of subterranean streams.

Visitors can only explore the cave with a guide who leads groups through the safe and stable passages. Wear sturdy shoes and bring a jacket since the underground environment remains cool and damp year-round.

The cave contains one of Europe's deepest underground water sources, demonstrating how water flows through hidden depths in remarkable ways. This geological feature makes the location fascinating for both scientists and nature enthusiasts.
