Grottes de Vallorbe

Grottes de Vallorbe in the Jura vaudois, Switzerland, rank among the most beautiful caves in Europe and have been open to the public for over 40 years. Visitors explore an underground river (the Orbe) that carved the limestone over millions of years before emerging as a spring at the cave entrance. Inside, a mineral exhibition called 'Le Trésor des Fées' showcases over 250 minerals from around the world.
