Lombrives Travel Guide

The Grotte de Lombrives, located in Ornolac-Ussat-les-Bains, is a sprawling cave system that extends over 39 kilometers across seven levels, making it one of the largest in Europe. The cave's history is as layered as its geological formations. Archaeological excavations have revealed evidence of human occupation dating back to the Neolithic period, with the cave serving as a shelter for Magdalenians and a burial site during the Bronze Age.Throughout the centuries, Lombrives has been a sanctuary and a stage for historical events. During the 12th and 14th centuries, Cathars sought refuge in its depths, and later, it became a hideout for Huguenots. Legends whisper of hidden treasures, including the Holy Grail, concealed within its chambers after the fall of Montségur. The cave's significance is further enriched by the legend of Princess Pyrene, whose tomb, according to Greek mythology, lies within the cave and marks the origin of the Pyrenees.A visit to Lombrives is a multi-sensory experience. The cave's vast chambers, adorned with stalactites, stalagmites, rimstone pools, and calcite crystals, create a mesmerizing landscape. The 'Cathedral Chamber,' is so large that it could house the Notre-Dame Cathedral in Paris.In more recent times, the Grotte de Lombrives hosted the 'Deep Time' scientific expedition in March 2021, during which 15 volunteers spent 40 days in the cave without clocks, daylight, or external communication, to study the effects on human behavior and perception of time.Visitors can explore the cave through guided tours that range from 1 to 5 hours. These tours lead visitors through the 'Passage of Crime,' the 'Grand Amphitheater,' and past the 'Tomb of Pyrene,' each with its own story and geological significance.
