Kotor Bay Boat Tour: Blue Cave, Mamula Island & Our Lady of the Rocks (3-hour)
Adventure Brief
A three-hour coastal cruise from Kotor that hits the Blue Cave, historic Mamula fort, wartime submarine tunnels and the man-made island Our Lady of the Rocks—perfect for photographers and history-minded travelers.
The motor hums, gulls wheel, and the limestone walls of the bay press in like a slow-moving amphitheater as you leave Kotor’s old pier. Salt spray dots your sunglasses and the first island—low and dark against the sky—slides into view: Mamula, a round concrete fort that has watched the Adriatic since the 19th century. On this three-hour circuit the sea becomes your road, carving a path through fishing villages, submerged tunnels, and that startling blue light inside a cave that seems to have been lit from within.
