The Experience

The speedboat leaves Kotor and heads into the Bay of Kotor toward the open Adriatic, a scenic run that takes roughly an hour to reach the Blue Cave. Once there, you get around 25 minutes to swim in water that glows bright blue—sunlight enters the cave and reflects off the seabed, turning the whole space luminous. The captain stays with the boat while you're in the water, and life jackets and safety gear are provided.

On the way back toward Kotor, the tour passes Mamula Island, a small circular fortress at the bay's entrance, then slows to enter the submarine tunnels carved into Luštica Peninsula—former military shelters you can explore by boat. The route then moves toward Perast, passing Our Lady of the Rocks and St. George Island, two small islands that form one of the bay's most recognizable views. You get 20 minutes of free time to walk Perast's narrow stone streets, take photos of the bay, or simply sit in the quiet before the 25-minute return to Kotor.

The boat is modern and fully insured, with a licensed captain who has run this tour for over a decade. Free coffee is available at the office before departure, and the captain will share local knowledge about the places you pass—though this is not a historical tour. Raincoats, blankets for winter, and secure storage for belongings are on hand. You'll need to arrive 30 minutes early; late arrivals cannot be rescheduled or refunded. The tour runs subject to weather; rough conditions may trigger a reschedule or refund.
