You will drive about 50 min north of Valencia city with your private guide and private vehicle to the small town of Vall d’Uixo in the province of Castellon to the beginning of the Sierra de Espadán mountain range. After a pleasant drive, we will experience a pre-historic cave to take a boat ride along the longest subterranean river in Europe. On this unique 45 min boat ride, we will see the natural cathedrals of Spain: Her caves, beautifully lit up as we journey into the center of the mountain. At this site, we also get to see pre-historic Iberian remains from the 1st millennia b.c. and 19th century hermitage along with beautiful views. This is a very calming and relaxing tour, great for all ages.

On our drive we will pass Sagunto´s Roman fort and several remains of Roman aqueducts and medieval bridges.

This is a great off-the-beaten path tour for families young and old with easy access to the caves and not too much walking once inside.

This tour can be combined with Sagunto, the city of Castellón or our hiking tour in Ain, as they are in the same vicini

Duration: 4.5 hours (For caves only)

Full-Day Options: To combine the cave visit with the Ain hike and abandoned Moorish castle or Roman and Jewish Sagunto, the tour would extend to 8 hours. Please indicate when you contact us, if you would like the half-day caves only or if you would like to make this a full-day tour.

Meeting Point: Train Station, Bus Station, Port, Hotel, or Destination of Your Choice

We are happy to arrange a meeting point that is most convenient for you. We will gladly collect you and drop you off free of charge anywhere in the vicinity of the city center, port, beach, or City of Arts and Sciences. We would also be delighted to pick you up or drop you off outside of the city center or at the airport for a small fee.   

***For Port Pick Ups Only: Your private guide will meet you at the ‘Acciona Transmediterranea terminal’ at the cruise ship port, where your ship might be docking anyway. If you dock elsewhere, you will be at a pier a bit further away with restricted access for vehicles and private pick-ups. In this case, the port authorities will provide a shuttle bus, free of charge, that takes about 5 minutes to get to the Acciona Transmediterranea Terminal, which is the only place private pick-ups are allowed. Your guide will be waiting for you at the terminal with a sign in your name.

Private, Comfortable Transportation: 

We provide private transportation in well-maintained, modern vehicles. For smaller groups (up to 4–6 people), your guide will often also serve as your driver in a clean, comfortable car or minivan. For larger groups, we arrange high-quality pre-booked minibuses or spacious taxi-vans with professional drivers. While we cannot guarantee a specific brand or model, you can always expect vehicles that are tidy, reliable, and suited to your group size for a smooth, enjoyable journey.  

IMPORTANT NOTE (for groups of 6): In my larger touring car, the middle two seats are spacious and comfortable, and the back seat is a three-person bench seat that might be a tight squeeze for some. Before I can confirm a booking for six people with this vehicle, I will need confirmation that you understand this arrangement before I accept the booking. If you prefer, I would be happy to arrange a private coach and driver in addition to your guide. Please let me know that this is your preference when you submit your pre-booking form.
