Take a drive through the hills and visit Palionnisos beach. It's a secluded spot, far from the hustle and bustle. There are a few good options for food and drinks, and the beach itself is quite nice. Be sure to try the local offerings on either side of the beach.
This is undoubtedly one of the top beaches on Kalymnos. It features a beach bar and several sun beds. The sea and the beach are covered with small stones. The beach bar offers excellent food and drinks. Sunbeds are priced at 10€ for a pair (summer 2023).
