Float into a cobalt-lit cavern and swim along limestone cliffs on a private speedboat from Dubrovnik. This five-hour tour to Koločep (Kalamota) combines snorkeling, cave exploration, and optional cliff jumping with a private skipper and GoPro for photos.

You push off from Port Gruž and the city shrinks behind you — the speedboat cleaves the Adriatic, salt spray urging you forward. In about 20 minutes Koločep (locally Kalamota) appears: low, green, and rimmed with pale limestone cliffs. The skipper eases the boat near a narrow entrance where the Blue Cave’s interior glows an impossible electric blue; sunlight refracts through the water and the cave seems to inhale the sea.

Go early for calm seas
Morning departures usually mean flatter water and the best light inside the Blue Cave for that intense blue glow.
Bring a waterproof bag
Keep phones, keys, and travel documents dry — the boat can rock during entry and exit from caves.
Know your limits for cliff jumps
Cliff jumping is offered in sheltered spots but check depth and ask the skipper; jump only if comfortable and experienced.
Use reef-safe sunscreen
Protect the marine environment and your skin — apply before boarding to avoid greasy masks and gear.
Swimwear and quick-dry towel
Comfortable swimwear and a towel are necessary for swims and changing on the boat.
