The Best Sea Caves in Mallorca to Explore

Cova des Coloms: The Cave Most People Mean

When people search for sea caves near Porto Cristo, they're usually thinking of Cova des Coloms, near Cala Varques. It's one of the best-known sea cave experiences on this coast — not necessarily because it's the largest cave on the island, but because it combines a few things that are hard to find together: a sizeable chamber, a partial opening to the sky that lets natural light flood in, and a clear, swimmable pool of brackish water inside.

It's also the cave that most guided sea cave trips from Porto Cristo are built around, which makes it the natural starting point for this list. We cover it in full — including the Menorca naming mix-up, what to expect inside, and how to get there — in our dedicated Cova des Coloms guide.

The Pirate Cave, Cala Varques

A short distance from Cova des Coloms, in the same general area around Cala Varques, a smaller sea cave is sometimes nicknamed the "Pirate Cave" by visitors and local guides. It's shallower and more compact than Cova des Coloms, and is often explored by snorkellers swimming out from the cove itself rather than as part of a formal tour.

It's a good example of the kind of casual discovery that's possible if you're already comfortable swimming in open water along this coastline — though as with any sea cave, conditions can change quickly, and it's worth checking conditions and going with others rather than alone.

A Note on "Blue Cave" Names

You may come across references to a "Blue Cave" in Mallorca, often by comparison to famous sea caves elsewhere in the Mediterranean, such as Capri's Blue Grotto. Mallorca doesn't have a single, official cave with this name — the term tends to get applied informally to whichever cave a visitor found with particularly vivid blue water on the day, often depending on light and weather conditions. If you've seen the term used online, it's worth treating it as a description rather than a specific, bookable location.

Why You Cannot Explore Every Cave on Mallorca

Mallorca is honeycombed with cave systems, and some of them are genuinely vast. The Cova des Pas de Vallgornera system, for example, is one of the longest known cave systems in Spain, with passages running for tens of kilometres underground. Exploring caves like this requires advanced cave-diving certification, technical equipment, and often specific access permissions — it is not something that's arranged as a holiday activity, and it isn't open to casual visitors.

Are These Caves Lit Inside?

No. None of the sea caves described here have installed lighting — that's one of the clearest differences from a show cave like the Cuevas del Drach. Light comes either from the cave entrance, from a natural opening above (as at Cova des Coloms), or from the waterproof headlamps that guides provide. It's part of what makes the experience feel different: you're seeing the cave the way it actually looks, not the way it's been lit for an audience.

How to Visit These Caves

Most of the caves on this list can be reached on foot with a long walk and an open-water swim, but the more practical and considerably more comfortable option for most visitors is a guided boat trip from Porto Cristo. Our guide to sea cave tours in Mallorca compares the options in detail.
