Pserimos extends over a surface of 15 km², counts approximately 150 inhabitants, and is ideal for peaceful holidays. Traces of an ancient settlement have been discovered on the island, which some archaeologists have identified with the town of Perraiotan. West of Pserimos lies the tiny island of Plati, a part of which forms a separate rock-islet, named Nekrothiki. All coasts are ideal for swimming, with the most exceptional one being Vathy Bay. Getting to Pserimos is easy by boat from the larger nearby islands of Kos and Kalymnos.
