Grotte de Vallorbe

The Grotte de Vallorbe lies in the canton of Vaud and is considered the cave with the largest underground river in Switzerland. Among other things, whisky is stored in the caves. The interior of the cave features impressive, towering ceiling formations as well as illuminated rock structures reminiscent of a combination of spaghetti, worm-like cells and cauliflower. In the area with the highest ceiling, the way sound travels is particularly special, which is why specially selected music is played there.
