The Galleries & the boat trip
An advice before buying your ticket – if you are claustrophobic, do not enter the caves. You will have a visit of about 1050 meters long, of which 800 meters are covered on water, by boat. At some point the boat will stop to a small pier where you get down and around 250 meters you do it on foot, through a narrow corridor. After that you get inside the boat again and you traverse the channel till you get back to the main entrance.
The visit lasts approximately 45 – 50 minutes. The cave has a constant temperature of 20ºC throughout the year. Inside you will discover in each gallery paintings and engravings declared by the UNESCO. The cave is illuminated with led lights that help its conservation and prevents green in the cave.
You will only be allowed of taking pictures and videos on your way back to the main entrance that is because of the danger of not hitting your head on rocks or standing up and paying attention to your phone, not the rocks in front of you or above you.
Your visit will be accompanied by a Guide-Barquero, sailing the underground river, more than three kilometers long.
As you sail through the different galleries you will see stalactites, flowstones and other karst formations hanging from the ceiling and emerging from the ground, all shaped.
The highlight is the tour round the crystal clear waters that goes by the Azul (Blue) Pond, Murciélagos (Bat) Room, “Boca del Forn”, Diana and El Diablo (Devil) lakes.

Importance of the caves
The main areas and galleries within the Coves de Sant Josep are the Gallery of the Iberian Settlement and the Singin’ in the Cave area, which features the navigable river. The “Singin’ in the Cave” experience includes traversing the subterranean river, while the “Gallery of the Iberian Settlement” highlights the ancient history of the location.One important and curious aspect of the galleries and the river inside them is the fact that the water is fresh and can be drinkable.
The water is responsible for shaping the cave’s impressive rock formations and the growth of stalactites and stalagmites over thousands of years.
According turismolavallduixo.com, in order to enlarge the space for the boat tour, the narrow passages were dynamited, and the underground river was drained to remove debris and rocks. From that point on, the number of tourists grew exponentially from over 3.000 visitors in 1960 to 20.000 the following year. This number doubled in 1962 and Valencian travel agencies began to include a visit to the site among their regular tourist excursions.
