Sea Caving at Cova des Coloms, Mallorca's Swim-In Adventure

Most visitors to Mallorca know the island for its beaches and famous show caves, but few venture into Cova des Coloms—a hidden cavern that can only be reached by a thrilling swim through the open sea. This wild, ‘swim-in'cave near Cala Romàntica offers a rare combination of adrenaline, beauty, and pure discovery.

Cova des Coloms: A Swim Through the Blue

Reaching the cave is an adventure in itself. From the sandy curve of Cala Romàntica, you’ll swim about 200–250 meters along the coastline until the dark mouth of the cave appears in the cliffs. On calm days, the water glows turquoise; on rougher days, the waves can make the entrance impossible. This is why timing—and fitness—matters.

Inside the Cave

Once you slip past the threshold, daylight fades and the cave opens into towering chambers dripping with stalactites. Pools catch the glimmer of your headlamp, bats dart overhead, and the acoustics transform every sound into an echo. Unlike Mallorca’s developed caves, Cova des Coloms is unlit and unmarked—what you see is raw, elemental nature.

Safety First

Caving here isn't for the faint of heart. It's an adventure activity with inherent risks, but the experience is made safe and enjoyable with the guidance of local experts who prioritize your safety.

Go with a guide: Companies in Cala Romàntica and Porto Cristo offer half-day excursions, providing helmets, wetsuits, and waterproof lights.

What to bring: Swimwear, sturdy water shoes, and a dry bag for anything essential. Avoid carrying valuables.

Best time to go: late spring through early autumn, when seas are calmest. Morning outings often mean lighter swell and fewer crowds, ensuring you have the best experience possible.

Who should skip it: Non-swimmers, those afraid of enclosed spaces, or anyone with limited fitness. Children under 12 are usually not recommended.
