Skip the crowds and take a private speedboat through Kotor Bay’s most dramatic spots: the man-made island of Our Lady of the Rocks, Cold War submarine tunnels, Mamula fortress, and the luminescent Blue Cave—plus time to swim in the Adriatic.
More ways to explore the area's outdoor wonders
The morning light slices across the Bay of Kotor and the water answers with a slow, bright clap. You step onto a compact speedboat in Kotor—salt on the air, the old town’s stone roofs shrinking behind you—and the skipper punches the throttle. The bay pulls you forward: first toward the tiny, plaster-white island of Our Lady of the Rocks, then inland through shadowed submarine tunnels and past a low, rusting fortress before the hull slips into an electric-blue mouth of rock known simply as the Blue Cave.
