Kimolos is the only one of the three islets off Milos that is inhabited. In fact it is the smallest of the inhabited islands in the Cyclades with a surface area of only 36 square kilometres. The island has about 800 inhabitants and mining is still the main source of income. In the past, chalk was quarried here but the supply has now been exhausted. Only one kilometre of water separates Kimolos from Milos. The island is circular and its highest point is 358 metres (1175 feet).

Excavations have established that the island was inhabited during the Mycenaean period and the island was renowned in antiquity for its chalk. In 1207 the island became part of the Latin Duchy of the Archipelago and was ruled by the Gazzadini family until the Turks arrived in 1536. During the period of Ottoman rule the island was used as a base by pirates who attacked both Turks and the other Cyclades islands.

Ferries arrive at Psathi and the Chora is an uphill 15 minute walk. Here you will find some accommodation, a couple of tavernas, shops, an OTE, a post office and an archaeological museum. Near the town there is a kastro and the 16th century church of Chryssostomos. The remains of the ancient city of Kimolos and the medieval town with its defence walls stand on the summit of the island. Further away, the remains of a Venetian fortress, now called Paleokastro, can be visited.

Those in search of a quiet beach holiday should find rooms in Alyki.
