Sifnos lies in the Cyclades between Serifos and Milos, west of Delos and Paros, about 130 km (81 mi) (80 nautical miles) from Piraeus (Athens' port).
Sifnos is the fourth island in the Western Cyclades and is easily reachable by ferry and high-speed catamaran from Pireaus. Sifnos is a mountainous island with fertile valleys, beautiful beaches and several towns.
It has a long history and has been inhabited since 3000 BC. For people who are looking for the 'real Greece' and yet still wouldn't mind a little nightlife, Sifnos is the place to go. Great for honeymooners, couples, families with children and romantics. Sifnos was the first island in Greece to hook up their plumbing to a purification and waste treatment plant which makes Kamares one of the cleanest beaches in Greece and certainly the cleanest port.
