The whine of the outboard eases as the city walls recede and the Adriatic opens blue and blunt. Salt spray perfumes the air; limestone cliffs cut sharp against a sky that feels bigger at sea. On this four‑hour speedboat outing from Dubrovnik you skim past Lovrijenac Fortress, slip into the glowing chamber of the Blue Cave off Koločep, and anchor in the sheltered turquoise of the Blue Lagoon near Brsečine.
