Kolocep Island, also known by the Italian name Calamotta, is one of the three populated Elafiti Islands. It is the closest of the archipelago to the coast of Dubrovnik; in fact, it's Croatia's southernmost inhabited island, just 20 kilometers from the border with Montenegro. It's about 1km from the coast if you swim! From the port of Dubrovnik it's a good bit further, but there are five daily ferries. A return ticket costs 36 kuna, and the ferry takes half an hour to travel the five kilometres from Gruz harbor to the island. Once there you can enjoy beautiful beaches, all to be explored on foot as no vehicles are allowed on the island. Only 150 people live here, but there are a few hotels and restaurants. Kolocep was once a strategic point for ship-building, and was conquered by the Greek and Roman Empires, and later Napoleon.
