Elafonisos is a small Greek island between the Peloponnese and Kythira. It lies off the coast of Cape Malea and Vatika. The area of the island is 19 square kilometres (7 square miles).
The population is between 300 and 350 during the winter but increases dramatically in the summer months. During July and August the number of tourist visitors reach over 3,000 per day (bringing with them some 1,600 cars). Many people visit the island for its light coloured, sandy beaches. Among the most well known of its beaches are Sarakiniko, Fragos (Simos) and Panagias Nissia, all filled with blue-green waters.
Elafonisos is by far the largest inhabited island in the Peloponnese archipelago, and the only one that is a separate municipality. There are also some archaeological discoveries to explore on the island and in the surrounding waters. The main church of the community is Agios Spyridon, which is built on a tiny separate piece of land which is connected by a bridge over shallow waters to the rest of the island. The community's land area also includes 3 km2 (1 sq mi) of the mainland consisting mainly of the famous Punta Beach.
