Sant Josep Caves

The Coves de Sant Josep, located in La Vall d'Uixó, Castellón, are a cave system housing the second longest navigable underground river in Europe. This natural site features galleries and passages extending beneath the mountain, offering a boat trip through a landscape of geological formations and crystal-clear waters. The experience immerses visitors in an underground world where artificial lighting highlights the textures and colors of stalactites and stalagmites.

During the visit, guests glide silently in small boats along the subterranean river, allowing close observation of the rock formations and the unique fauna inhabiting this ecosystem. The route includes wide and narrow sections, with ceilings and walls that reveal the cave's geological evolution over thousands of years.

This karstic cave system was formed by water eroding limestone, shaping the galleries and riverbed. The cave has served as a natural refuge and a focus for geological and biological studies, as well as a tourist attraction connecting with the culture and landscape of the Valencian Community.

Advance booking is recommended, especially during peak season. The tour lasts about one hour and is suitable for visitors with average mobility, though it is not wheelchair accessible. The visit is family-friendly and ideal for school groups; comfortable clothing and appropriate footwear are advised. Entry is free for children under a certain age, with updated prices available on the official website.
