Take a caving tour and explore the inside of a mountain
Visit the inside of a mountain during a 2-hour tour and discover the miracles of the subterranean world. Large chambers and narrow passages are the visible results of nature’s intricate work.
Caves emerge and evolve. They bear witness to the history of the mountains, the formation of limestone rocks some 400 million years ago, the uplift of the Alps and the erosion of the massif.
