Discover Mallorca’s stunning sea caves on a small-group boat tour, swimming, exploring underground chambers, and enjoying a thrilling speedboat ride.
Experiencing Mallorca’s marine caves via a sea caving tour offers a rare peek into an underground world filled with shimmering lakes, dramatic stalactites, and a sense of adventure. This particular excursion, run by Skualo Porto Cristo, promises a small-group setting, a speedboat ride along the east coast, and friendly guides dedicated to making your experience memorable. With a rating of 5.0/5 from 117 reviews, it’s clear that many travelers leave feeling like they’ve uncovered something truly special.
What makes this tour stand out? For us, it’s the combination of stunning natural beauty, personalized attention, and accessible yet adventurous activities. The fact that it’s limited to just 10 participants means you’ll never feel lost in a crowd — which can be a rare thing in popular Mallorca excursions. That said, a possible consideration is the moderate physical fitness level needed, as you’ll be swimming, climbing rocks, and navigating tight cave passages. This tour is perfect for adventurous families, curious explorers, or anyone looking to add a splash of excitement to their Mallorca trip.


This tour is designed for those looking for a short, action-packed adventure that combines marine exploration, underground discovery, and scenic boat rides. Starting at Skualo Porto Cristo, a diving and adventure sports center, the journey begins with a quick equipment fitting — wetsuits and safety gear are provided, so no need to worry about bringing your own. Once geared up, you’ll hop aboard a speedboat for about 15 minutes along Mallorca’s eastern coastline, enjoying the breeze and spectacular sea views.

The boat ride itself is a highlight, offering an adrenaline rush and a chance to soak in the rugged coastline. Reviewers mention that the thrilling boat ride sets the tone for the adventure ahead. Many guests appreciate that the meeting point at Skualo Porto Cristo is accessible, close to public transportation, making it easy to reach without renting a car.
Upon arrival at the cave’s entrance, the guides — like Mark, who’s praised for being “nice, funny, and knowledgeable” — give a quick safety briefing and instructions. You’ll then swim from the boat to the cave entrance, which some find a bit challenging if the waves are lively, but the guides remain attentive and helpful. The guided tour inside is what truly steals the show.
Once inside, you’re met with an otherworldly landscape. The cave’s interior is illuminated by your flashlights, revealing stalactites and stalagmites in various formations. The crystal-clear lakes reflect these formations with a mirror-like quality, making it feel like you’re swimming through a fantasy. Reviewers note that the water is a mix of crystal-clear and brackish, adding to the surreal environment.
Many guests comment on the beauty and serenity of the underground lakes, which seem untouched and pristine. Some portions of the cave involve climbing rocks or navigating through narrow passages, so a moderate fitness level helps, but guides do their best to make the experience accessible for “everyone from kiddos to adults.”
Multiple reviewers praise the guides, noting their friendliness and professionalism. “Mark was funny and knowledgeable,” says one guest, which makes the inside tour not only educational but entertaining. The guides are also attentive, helping those who might feel nervous or unsure about swimming or climbing.
One reviewer, Claire, highlights that the business is family-run, which adds a personal touch to the experience. She appreciated how the guides made the activity “as accessible as possible for everyone,” including children. That’s important if you’re traveling with family or less experienced swimmers.
The duration of around 2 hours fits well into a Mallorca day, allowing time for other activities afterward. The cost of approximately $105 per person seems reasonable considering the combination of a boat ride, cave exploration, and guided commentary. Some mention that they drove over an hour to get there, but many found the experience worth the travel.
The cave is best experienced in good weather; poor weather can lead to cancellations, but the tour offers full refunds if canceled due to weather, which adds peace of mind. The max group size of 10 guarantees personalized attention, and the small groups felt less crowded and more intimate.

This caving adventure is ideal for adventurous travelers craving a mix of sea, land, and underground exploration. It’s perfect for those comfortable with swimming and light climbing. Families with children who are moderately active will find this engaging, especially given the guides’ efforts to make it accessible. If you’re after spectacular scenery, a thrilling boat ride, and a hands-on experience of Mallorca’s caves, this tour hits the mark.
It’s also excellent for those who love learning — the guides share interesting facts about the cave formations — and for photographers eager to capture jaw-dropping images of lakes and stalactites. Budget-wise, it offers good value for a two-hour adventure that covers both land and sea.
For anyone seeking a unique, active, and scenic experience in Mallorca, this sea caving tour offers genuine value. It combines adventure, natural beauty, and expert guidance, creating a memorable outing for solo travelers, couples, or families. The small-group format means you won’t feel like just another face in the crowd, and the friendly guides and professional operation ensure safety and fun.
If you’re curious about Mallorca’s underground wonders, love water activities, or just want a thrilling experience that’s off the usual tourist path, this excursion is a fantastic choice. Keep in mind the physical component — swimming and climbing — but rest assured that everyone from kids to adults has left glowing reviews about how accessible and rewarding the trip was.
Ultimately, this tour offers an authentic, fun-filled peek into Mallorca’s hidden marine caves, making it well worth the price for a short but spectacular adventure.
