Why: A clean and postcard-pretty organised beach, bracketed by green mountains, that’s well-equipped with family-friendly amenities.
Highlights: Lovely views of Agios Panteleimonas church, rock climbing and playground for kids, beach bar for toasties and ice-creams.
You’ll Pay: Nothing for the beach. Just pay for sun loungers and umbrellas if you want them.
