A Fresh Look at Mallorca’s Underwater Caves – A Guided Tour Worth Considering
This Mallorca tour offers an engaging journey into the island’s lesser-known cave systems, combining a hike, swimming, and storytelling. With a duration of about 4.5 hours, it promises a mix of adventure and natural beauty, guided by knowledgeable experts in both English and Spanish. I’ve seen travelers say it’s a truly memorable experience, and I can see why – it’s not just a walk-through, but a full-on exploration of stunning lakes and jaw-dropping formations.
Two things I particularly like about this tour are its immense value for the price (around $91 per person) and the personalized experience with small group sizes limited to 10 participants. The guidance by friendly guides like Luís and Vanessa adds a genuine, approachable touch that makes the experience feel both safe and fun. The highlight is definitely swimming in the cool, clear cave lakes and marveling at formations like stalactites and stalagmites—this isn’t something you do every day.
A possible consideration is the physical aspect: the tour involves about 2 km of walking on flat terrain and a half-hour hike uphill to the cave, plus swimming—so it’s best suited for those comfortable with moderate activity. If you’re not into swimming or have mobility concerns, this might not be your first pick. Also, it’s a good idea to bring a change of clothes and be prepared for a bit of exertion, especially since the hike can be tiring in places.

Exploring Mallorca’s Hidden Underground Treasures

When I think about Mallorca, I often picture its beaches, but its cave systems are just as compelling. This guided tour takes you on a four-and-a-half-hour adventure into the heart of the island’s underground labyrinth, revealing lakes and formations that are rarely seen by the average visitor.
From the moment you meet your guide at S’Estany d’en Mas, you can tell this isn’t your typical sightseeing trip. You’re handed a backpack with all the gear you’ll need—wetsuit, helmet, waterproof shoes—and receive a quick briefing. The walk to the cave, about half an hour, is a pleasant way to start soaking in the scenery, and the hike uphill adds a touch of physicality, which many reviewers find exciting rather than exhausting.
Once inside the cave, the real magic begins. As you swim into the interior lakes, you’ll be surrounded by towering stalactites hanging like chandeliers and stalagmites rising from the floor. The lighting provided helps highlight these natural sculptures, creating a surreal atmosphere. One reviewer, Sylvia, calls the stalactites and stalagmites “very impressive,” adding that “the hike in and out was sometimes funny, sometimes exhausting,” but overall a “great experience” with a friendly team.
An aspect I find particularly appealing is how guides like Luís share stories about how these caves formed, mixing facts with humor and legend. It’s a storytelling style that entertains and educates, making the experience more meaningful. Plus, spotting weird critters that call these caves home—imagine discovering tiny creatures in such a mysterious environment—adds an extra layer of intrigue.

The Logistics: What to Expect and How to Prepare
You’ll start your adventure on land, walking through a scenic area before reaching the entry point. The tour involves walking approximately 2 km on flat terrain and a half-hour hike uphill to reach the cave entrance, followed by swimming into the cave interior. Sometimes, if sea conditions aren’t ideal, the tour is adapted to access the caves by land, which is closer and more accessible.
All necessary safety gear—wetsuits, helmets, lighting, waterproof shoes—is provided, which is great for travelers who want a hassle-free experience. The small group size means you’ll get more personal attention, and your guide will be able to share stories and answer questions along the way.
The price of $91 per person offers excellent value, considering the gear, guided expertise, and access to one of Mallorca’s unique natural features. It’s worth noting that food and drinks are not included, so bringing water and snacks is a good idea, especially since the tour can be physically demanding.
Who Will Love This Tour?
This experience is perfect for active travelers who enjoy a bit of adventure and natural beauty. It’s great for those comfortable with swimming and walking, and who appreciate stories about geological formations. If you’re looking for a tour with a knowledgeable guide, stunning sights, and a sense of discovery, this fits the bill.
While small children under 9, wheelchair users, and non-swimmers should probably look for something more accessible, most other adventure seekers will find this a memorable highlight of their Mallorca trip.
Practical Tips for Your Cave Adventure
- Wear your swimwear and bring a change of clothes for after.
- Pack water, snacks, and a towel in your backpack.
- Wear closed-toe shoes—sandals or flip-flops aren’t allowed.
- Prepare for about 2 km of walking and a half-hour scenic hike uphill.
- Make sure you’re comfortable with swimming and walking moderate distances.
- Check the weather and sea conditions, especially on weekends, as the tour might shift from sea-based to land-based access.
