The journey begins with a roughly 80-minute bus ride from Valencia, giving you a chance to enjoy the scenic countryside of Castellón province. The bus ride itself is smooth, with most travelers noting it’s well-timed and comfortable. Once you arrive, the adventure kicks off with the core highlight—the boat trip inside the caves.
The boat ride is a highlight many reviews rave about. Nelson_O described it as a “great day for a boat ride” and appreciated the fascinating experience navigating Europe’s longest underground river. The boat glides gently through the waterway, allowing visitors to marvel at the stalactites, stalagmites, and formations that have taken thousands of years to develop. The guide, often named Edwin in reviews, is praised for being informative and personable, though it’s worth noting that explanations may be primarily in Spanish.
Following the boat trip, you’ll explore the dry gallery of the caves, where you’ll see the UNESCO-listed cave paintings. These ancient artworks, etched into the walls, add a historical depth that makes the visit more than just a natural marvel. One reviewer, Kathrin_B, mentioned that the time on-site was a bit tight, and the experience could benefit from a little more free exploration time, especially outside the main attractions.
The tour concludes with a walk through the dry gallery, offering a chance to appreciate the formations and artistic carvings up close. The entire experience lasts approximately 4 hours—this includes the bus journey, the boat trip, and the guided tour.
Roundtrip transportation from Valencia is included, which is a big plus for convenience. The bus ride is generally comfortable, with most travelers appreciating the scenic views along the way. The group size is capped at 52 participants, which helps maintain a more personal atmosphere, though the actual experience tends to be quite organized and smooth.

It’s perfect for those who don’t want to spend a full day traveling but still wish to see a significant underground site. It’s also a good choice for families, small groups, or curious travelers who appreciate guided experiences and easy logistics.
Some travelers, such as Kathrin_B, feel the short duration and tightly scheduled nature of the visit limit the free time for personal exploration. If you’re someone who loves lingering at sights or exploring independently, this might be a slightly rushed experience. Plus, the language barrier with guides may be a consideration if you don’t speak Spanish.
