If you’re seeking a truly unique experience in Mallorca, exploring its secret caves by swimming through crystal lakes tops the list. This guided tour, rated an impressive 4.9 out of 5 by nearly 100 reviews, offers a rare glimpse into the island’s underwater beauty. For around $91, you get about four and a half hours of underwater adventure, complete with expert guides, safety equipment, and unforgettable scenery.
What makes this trip stand out? First, the stunning formations inside the caves—stalactites hanging like chandeliers and stalagmites rising majestically from the ground—are sure to leave you in awe. Second, the guided commentary is both educational and humorous, with guides such as Vanessa, Antonio, Luis, and others sharing fascinating stories about how these caves were formed and their local legends. A third plus is the cool, clear waters that provide relief from Mallorca’s warm weather and a refreshing break from land-based sightseeing.
One thing to keep in mind is that this tour involves walking about 2 km on flat terrain plus a half-hour walk to reach the cave, so it’s best suited for those comfortable with some light hiking and swimming. Also, since it’s limited to small groups of 10, it’s an intimate experience, but that means spots can fill up quickly—especially during peak seasons. Plus, the tour is based on good weather, with some adjustments on weekends or bad sea conditions, including land-based alternatives to sea entry.
