It’s a cave system in Switzerland, close to French border.
Best thing in it is the underground river. It’s really a river, not just a stream. A lot of water, and a lot of energy. It’s crazy to see such a thing in a cave.
It’s not the easiest to get here, but also nice to take a walk around the cave.
