I remember stepping into cool shade and hearing only water and a guide’s soft voice. I did not expect to glide on an underground river that feels like a secret highway beneath the hills. The boat ride lasted about 40 minutes and it still ranks as one of my favorite travel moments.
Located in the Sierra de Espadán Nature Reserve near La Vall d’Uixó, this place balances calm logistics with real wonder. The hydrologically active system runs 2,750 meters, and visitors can float through 800 meters of the longest navigable underground stretch open to the public.
On the standard tour you see crystal waters, the Azul Pond, the Murciélagos Room, and lakes named Diana and El Diablo. Archaeologists also found Paleolithic remains and paintings, which make the visit feel like a short trip through time.
For planning, the visit is easy to book and great for most visitors who want a gentle adventure in a protected area. Contact covesdesantjosep.es or +34 964690576 to reserve your slot.

Caves Sant Josep Valencia: my overview of a navigable underground river and cave art
I felt the air change as soon as I crossed the threshold — cooler, quieter, and alive with the slow movement of water.
Why I picked this place: the Sierra de Espadán Nature Reserve frames the visit with Mediterranean pines and limestone ridges. That landscape makes the moment of descent feel immediate and immersive.

My tour experience inside the underground river
Boarding felt purposeful — a quiet group, a low light, and the slow dip of the boat into shadow.
Boarding the boat and the mix of river by boat plus short sections on foot
I climbed aboard at the dock inside the cavern where the guide gave a clear safety briefing and explained the flow of the tour.
The trip is mostly by boat, with a few short foot segments to stretch and view formations up close. The crew keeps movements slow to protect water clarity and calm the group.
The route I follow: “Boca del Forn” gateway to the navigable sections
Entering through “Boca del Forn” felt like a true threshold moment as we slid into the darker heart of the system. Gentle turns, low ceilings that require a slight duck, and wide chambers alternate along the route.
The guide times pauses so both sides of the boat can see Azul Pond and the Bat Room. He points out reflective surfaces and color changes in the mineral deposits that make for memorable compositions.
| Segment | Mode | Highlights | Notes |
|---|---|---|---|
| Entry (Boca del Forn) | Boat | Initial hush, low light | Brief safety talk at dock |
| Main stretch | Boat | Azul Pond, Bat Room | Stable seating, guided commentary |
| Short stops | Foot | Formations up close | Well lit, easy paths |
| Return | Boat | Reflections, quiet | Total ~40 minutes; fits a half-day trip |
“The pace kept us comfortable and curious; it felt like a well-told story told over water.”
Practical tips from my visit: wear closed-toe shoes for the on-foot parts, bring a light layer for cool air, and put the camera down sometimes to enjoy the ambient feel of this place.
