The motor hums and the harbor peels away as Chania’s stone quay shrinks behind you. Salt air pushes forward through the boat’s bow and, ahead, Balos opens like a shallow pool of turquoise—water so clear it dares you to step in. The day splits between two contrasts: the shallow, glassy lagoon of Balos with its pale sand and seashell-rimmed shoals, and the craggy island of Gramvousa crowned by a weathered Venetian fortress.
