The Caves of San José, in the town of La Vall d’Uixó in Castellón province, are one of the most unusual excursions near Valencia. The attraction is a long underground river, often described as the longest navigable one in Europe, that visitors explore in small flat boats, gliding through rock chambers lit from within. After the boat section the route continues on foot through galleries with stalactites, still pools and cool, damp air. It is a gentle, atmospheric outing rather than an adventure sport, and it is easy for children and older travellers, though the stairs and low ceilings require some care. The caves are around an hour’s drive north of Valencia, so this guided tour is one of the shortest day trips on offer, often done in a half day. With a rating of 4.6 and hundreds of reviews, it is a popular choice. Tours can be combined with other stops, such as a swim at a nearby thermal pool or a village visit, depending on the option you choose.
How to take it
Book the guided tour from Valencia, which includes the transport and the entrance, and choose the departure time that suits you. Wear shoes with good grip, since the paths can be wet, and bring a light jacket, because the temperature inside the caves is cool and steady whatever the weather outside.
What to expect
A quiet, shaded outing, which makes it a good choice for hot summer days or rainy days when the beach is not an option. The boat trip is short and gentle, and the walking section involves some stairs. Visitors who dislike enclosed spaces or low ceilings may feel uneasy. Guides usually speak Spanish and English, so check the language when you book. Photography is allowed in most areas, though low light makes it difficult to get good pictures without a steady hand.
Making the most of it
Combine the caves with another stop on a longer day, or keep the afternoon free for the beach or the old town. If you are choosing between the underground river and the Montanejos springs, pick the caves for a short, shady, family-friendly outing and Montanejos for an active day outdoors. Bring a camera strap and keep hands inside the boat.
