The finest Dubrovnik archipelago, Elaphite Islands, are located on the western side of Dubrovnik. The islands offer idyllic atmosphere, hospitality of the people and crystal clear sea with beautiful sandy beaches and hidden bays. Three main islands are Šipan, Lopud, Koločep. Šipan is the largest and most heavily settled. It has two little ports, Suđurađ and Šipan harbour. Lopud and Koločep are entirely car-free, and have true sandy beaches, very shallow ones, perfect for children and the popular local ball game called picigin. The famous Blue Cave on the Koločep island can be accessed by swimming on the south side of the island from one of the hidden bays. The clear blue sea surrounds the island. Koločep has always been known as an island of fishermen and coral-divers.
