If you’re craving something beyond the typical beach day in Mallorca, this Aquatic Cave Exploration offers a fascinating peek into the island’s hidden depths. With a guided journey through stunning caves filled with sparkling lakes and impressive formations, it promises an experience that combines adventure, natural beauty, and expert storytelling.
What really sets this tour apart is the way it balances adventure with accessibility.

While it’s rated as easy to moderate, potential participants should be comfortable with water and physical activity. This tour isn’t ideal for children under 9, wheelchair users, or non-swimmers, but for adventurous spirits who love a bit of exploration, it’s a perfect fit.
If you’re curious about discovering Mallorca’s underground mysteries, crave a mix of adventure and scenic beauty, and enjoy stories told with humor and insight, this tour will likely hit the mark.

This guided tour invites you to slip beneath Mallorca’s surface and explore a world few get to see. It’s not just about swimming in caves; it’s about the storytelling, the formations, and the sense of discovery. The tour lasts around 4.5 hours, making it a substantial half-day activity, perfect for those wanting a memorable adventure without overcommitting.
One aspect we love is how the guides, like Luís, blend expert knowledge with humor, turning what could be a daunting adventure into a fun, engaging journey. You’ll learn about the caves’ formation and history, all while marveling at stalactites that hang like chandeliers and stalagmites that seem to rise from the floor just for you.
A potential drawback is the physical aspect — the hike to the cave, combined with swimming, might be exhausting for some. The tour involves walking about half an hour to reach the cave entrance, then swimming into the caves, so good fitness and comfort in water are recommended.
This tour suits adventurous travelers, nature lovers, and curious explorers who want to experience something different, authentic, and visually stunning.

Your adventure begins at S’Estany d’en Mas, where your guide awaits near the stairs by the containers. After a brief safety briefing, you’ll receive a backpack filled with your wetsuit, helmet, lighting, waterproof shoes, and other gear. We appreciate this all-inclusive approach, meaning you won’t need to worry about bringing your own equipment — just your sense of adventure.
Next, you’ll walk approximately 30 minutes on flat terrain to reach the cave entrance. This walk isn’t strenuous, but it’s an opportunity to soak in the scenic surroundings. Once there, you’ll put on your wetsuit and headlamp, transforming into a true explorer ready to uncover Mallorca’s underground secrets.
The journey into the caves involves swimming with your guide, a highlight that makes this experience truly unique. Expect to navigate through jaw-dropping formations—stalactites hanging like chandeliers and stalagmites rising from the floor—creating a surreal, sci-fi set.
According to one reviewer, “The water cave with the stalactites and stalagmites was very impressive,” capturing the visual magic of the experience. The excitement of swimming into this mysterious world is complemented by your guide sharing stories about how these formations came to be, adding a layer of storytelling that keeps you captivated.
While the focus is on geology and scenery, you might also spot some bizarre critters that call these caves home. It’s a reminder that even underground, life will find a way, making every moment more fascinating.
After exploring the caves, you’ll return to the surface, likely with a camera full of memorable shots. The entire journey is about lasting impressions and a feeling of accomplishment—an underwater adventure you’ll talk about for years.

This tour is rated as easy to moderate, suitable for those comfortable with walking and swimming, but not for small children or non-swimmers. The physical aspects mean it’s best for those in reasonable health and with a sense of adventure.
Starting times vary, so checking availability in advance is key. You can reserve now and pay later, offering flexibility if your plans change. The activity ends back at the starting point, making logistics straightforward.

At $91 per person, this tour offers exceptional value given the inclusion of all gear, a guided experience, and the unique opportunity to see Mallorca’s underground lakes and formations up close.

You’re paying for expert guidance, high-quality equipment, and an immersive experience. The chance to swim in crystal-clear, cool waters surrounded by stalactites and stalagmites makes this a memorable highlight of any Mallorca trip — especially for those craving something more than the usual sunbathing.

From the two reviews, it’s clear that guides like Luís and Vanessa elevate the experience. Sylvia called her tour “a great experience,” emphasizing the excitement and the team’s friendliness. She also pointed out that the hike and exploration required concentration, which adds to the sense of adventure.
Another traveler praised the “passage à la nage” (swimming access) as “the adventurous side,” highlighting how the combination of land and water adds a thrill. The storytelling, anecdotes, and humor shared by guides make the experience engaging and informative.
