Slip from Kotor’s harbor into a pocket of cobalt: the Blue Cave’s underwater light show, a swim in glassy Adriatic water, and quick stops at Mamula and Our Lady of the Rocks make for a compact, history-steeped boat tour. Practical details for timing, what to bring, and what to expect on this three-hour outing.

The hull nosed into a shadow at the base of a knife-edged cliff, and sunlight sliced through the narrow entrance to light the water like spilled cobalt paint. For three hours the sea does the guiding: it draws you through Luštica’s carved limestone, past concrete ribs of wartime submarine pens, and around the squat silhouette of Mamula Island where stone once meant confinement.
