Pserimos extends over a surface of 15 km2, counts approximately 150 inhabitants, and is ideal for truly peaceful holidays. In the island they have discovered traces of an ancient settlement, which some archaeologists tend to identify with the town of Perraiotan. In the west side of the island, there is a small island called Plati, a part of which forms a separate rock-islet, named Nekrothiki. All the coasts are ideal for swimming, with the most exceptional one being the Vathy bay. Pserimos is located 6 n.m. SE away from Kalymnos island.
