Gournier Cave

Gournier Cave is a cave system with an underground river flowing through limestone formations in the Vercors Massif. The cave contains a lake at its entrance and passages that branch through the rock, creating a network of connected chambers.

The first documented exploration began in 1899, with a second major expedition in 1947 that discovered extensive sections and fossil remains. These early investigations established the cave as an important site for understanding underground geology.

The cave represents a significant location for French speleology, drawing researchers and explorers to study its geological formations and underground water systems.

Visitors should expect cold temperatures around 6 degrees Celsius and bring suitable clothing and gear accordingly. Waterproof clothing, protective equipment, and reliable lighting are needed to safely navigate through the damp passages.

The cave offers multiple entry points to the river system and contains rare limestone formations found in few other caves in the region. These geological features make it particularly interesting for researchers and curious visitors alike.
