The Coves de Sant Josep open at the foot of the Sierra de Espadán, at the far edge of the town of Vall d'Uixó, and a navigable underground river runs through them. You board a flat-bottomed boat pushed along by a boatman who pulls on the roof, you pass under stretches low enough to make you duck, then you step ashore and finish on foot through a dry gallery. It is twenty degrees inside all year round, which in summer changes the shape of the day. The visit takes a little under an hour, but with the drive the stop fills half a day.

Getting there

  • You come into Vall d'Uixó and cross the town: the road ends in the forecourt of the caves, with no narrow stretches
  • Beside the entrance there are 8 motorhome pitches and a large mixed car park, asphalted, level and lit at night
  • The general car park is free and takes medium sized vehicles
  • From the car park to the entrance is a few minutes on foot, and there are steps at the cave mouth

Practical information

Duration the guided visit lasts 45 to 50 minutes, 800 metres by boat and 250 on foot; with the drive the stop fills half a day

Price 18 euros, 12 euros from 3 to 12 years old

When to go April to May and September to October

Suitable for any age in good health, with the caveat that under the age of 3 the transfer from the boat to the walking section is awkward and that the operator advises against the visit for anyone suffering from claustrophobia, agoraphobia or severe lung disease; not fully wheelchair accessible, since the walking section has steps and varying headroom, while the boat section is accessible with assisted transfer: anyone with reduced mobility is better off calling ahead

Booking worth booking online on the official site or by telephone, above all in summer; tickets are also sold at the desk, but the daily places are limited; arrive 10 minutes before your time, 30 minutes for the kayak outings
