Locals come to Orebić and nearby for its beaches. The nicest one is Trstenica, sandy, with a few bars and a section for naturists. It’s a 20-minute stroll east of the ferry terminal.
Boats make regular journeys to Viganj, a popular spot for windsurfing.
Excellent beaches stretch either side of the main road too. Prapratno, 3km west of Ston, is secluded and sandy.
