The coach eases onto the coastal road and the sea broadens until the town fades behind you—by mid-morning the boat is cutting through turquoise water and the horizon opens to two of Crete's most photogenic places: the rocky islet of Gramvousa with its crumbling Venetian fortress, and the shallow, jewel-toned lagoon of Balos.
