Discover the San José Caves, an underground river flowing 2.5 km beneath striking rock formations. With a constant temperature of 20°C, it is Europe’s longest navigable underground river. Known as “the heart of the earth,” the caves are filled with stalactites, stalagmites, and centuries-old cave drawings. Thanks to reconstructions and lighting installed in the 1920s, the route is now safe and fully accessible to visitors.
