Description of Coves de Sant Josep or Saint Joseph

Coves de Sant Josep or Saint Joseph's caves is a cave system where certain tunnels are accessible by boats. The caves of San José, located in the natural area of the same name, are a system of natural caves located in the municipality of Vall de Uxó (Castellón) Spain. The cavity represents an active upwelling developed in limestones during the middle Triassic period, but despite the multiple visits of cavers, the origin of the river and the end of the cave are still unknown. Grotto whose temperature remains constant at 20 ºC in the interior of the cave throughout the year, and with its current 2,750 meters, represents the longest cavity in the province of Castellón and the 2nd in the Valencian Community. It is the longest navigable underground river in Europe.


Before the advances of the 20th century, important historians such as J. Cavanilles, Sebastián Miñano, or Pascual Madoz, already cited in their works on geography the existence of Coves de Sant Josep. It was also recorded that the cavity was known since the Upper Paleolithic (about 17,000 years ago), as evidenced by the archaeological sites found in the mouth of access with the cave paintings of the Magdalenian period. Even the proximity of an Iberian town also indicated that during the Iberian era the cave was known and explored, as during the long Roman rule, at the sight of a tombstone found dedicated to Caio Cneo Crassus, son of the Roman consul Marco Licinio Crassus .
