The cavern is approximately 80 meters wide and 250 meters deep.
It was discovered in 1968 by a team of local speleologists.
The temperature remains a constant 14 degrees Celsius throughout the year.
It is part of a complex system of underground rivers that resurface further down the Clamoux valley.
The cave contains a rare array of aragonite crystals and calcite draperies.
The site hosts 'The Great Abyss' adventure course, which is one of the deepest underground zip-line experiences in Europe.
The Gouffre Géant de Cabrespine is one of the world's largest accessible caverns, boasting a central chamber voluminous enough to house the Eiffel Tower. It is a vertical karst feature located in the Montagne Noire region of the Aude department. Visitors descend into the abyss via a walkway system that provides access to unique geological formations and mineral draperies. Adventure options include the 'Accro Grotte,' a subterranean aerial adventure course featuring zip lines and suspended bridges. A glass-bottomed belvedere offers a vertical view over the 200-meter-deep floor. The site utilizes professional lighting to highlight crystalline structures and subterranean rivers. Geologically, the cave represents a significant intersection of limestone erosion and tectonic activity.
