In three brisk hours from Kotor’s waterfront you can visit the baroque church on Our Lady of the Rock, swim inside the radiant Blue Cave, pass the austere Mamula Fortress and cruise into Cold War–era submarine tunnels. This compact boat tour packs history, geology and a swim into one memorable loop.

The boat eases away from Kotor’s old stone quay and the world tilts toward water: cliffs drop sheer into the Adriatic, gulls wheel and the town shrinks to a cluster of terracotta roofs. Within minutes the captain points and the island of Our Lady of the Rock slides into view—white church walls catching the sun like a lighthouse for sailors. The tour moves with an economy of pleasures: a quick shore visit, the flash of turquoise at the Blue Cave, a slow pass around Mamula Fortress, and the claustrophobic hush of a submarine tunnel cut into the limestone.
