Lombrives Pyrenees
History, Myths & Legends.
Enigmatic. Fascinating. It is recognized as the LARGEST CAVE IN EUROPE .
The original point of the creation of the Pyrenees according to Greek myths. Shelter, burial place for prehistoric man, sacred Cathar land, refuge, hiding place, mystical place for kings…
Humans have ventured into Lombrives since the dawn of time and have left us thousands of traces, signatures and symbols, some of which remain unexplained…
Today, Lombrives is one of the most emblematic sites in Ariège. It continues to write its history: it is the scene of unprecedented scientific experiments on human adaptation and the preparation of future space missions.
At the initiative of the French National Centre for Space Studies (CNES) and the Human Adaptation Institute, it hosted, among other things, the DEEP TIME expedition in 2021 and 2025, a pioneering expedition in extraordinary scientific experiments. You've probably heard of it: 15 people/40 days underground, outside of time and without any contact with the outside world.
"At the Heart of the Earth: A fascinating, timeless immersion from the origin of the Pyrenees to futuristic scientific experiments."
Unforgettable concerts for an evening
joyful, family-friendly and unusual
By candlelight...400m underground...
A concert in Lombrives, you don't know about it?
Of course, nothing compares!
An approach hike through the mountain (or by our little tourist train). A candlelit labyrinth more than 400 meters underground. A "hole" in the rock larger than Notre Dame Cathedral . "Natural armchairs" in the cave's rimstone pools. Exceptional acoustics . Very low prices making culture accessible to everyone. A program that delights young and old alike. Exceptional artists .
(Important recommendation: very warm clothing, good shoes, a small blanket to wrap yourself in, a square of chair or a small cushion for more comfortable seating, and a level of physical fitness that allows you to walk 1.5 km on natural ground)

An unusual, relaxing, meditative, introspective, or contemplative experience ... There's something for everyone!
Exploring this wondrous natural world begins with a hike up a trail to the cave entrance (1.4 km on a hiking path, about a 20-minute walk, or, if you prefer, by our little train). Under the cave's archway, your guide will lead you into its vastness. Galleries of exceptional diversity, of incomparable historical and geological significance:
You cross the Carina, walk along the fault line, and take the Passage of Crime. There you are, in the magnificent Amphitheater: a sacred cathedral, conducive to contemplation but also to cultural events. After the grand staircase, the upper level opens onto the Gallery of the Great Cemetery. You then pass through galleries adorned with curious concretions. Here you are before the Tomb of Pyrenees, the ancestor of the Pyrenean people, according to ancient Greek myth. Further on, the Lake with its mysterious undulations...
