A navigable underground river

An underground river flows through the Sant Josep Caves, which enables you to enjoy an amazing natural phenomenon.

The Sant Josep Caves are situated in the Sierra de Espadán Nature Reserve. They hold one of the few navigable underground rivers in Spain, which is 2,750 metres long, out of which 800 are suitable for tourist visits. It is a magnificent example of a hydrologically active cave, where remains of Palaeolithic sites and cave paintings have been found. The highlight is the tour round the crystal clear waters that goes by the Azul (Blue) Pond, Murciélagos (Bat) Room, "Boca del Forn", and Diana and El Diablo (Devil) lakes, amongst others. Some of its most characteristic formations are: the Medusa, la Cascada de la Flor and Portal de Belén. The visit lasts 40 minutes and is covered mainly by boat. It is suitable for everyone and an additional caving/tourism visit can be booked.
