Located in the western Cyclades group of islands, the Greek island of Kythnos lies between the islands of Kea and Serifos and is around 100 km from the port of Piraeus. The small island, with a land area of around 100 sq. km and a coastline of 100 km, has about 100 beaches although many of them are inaccessible by road. The main villages on the island are called Messaria or Kythnos (known as Chora to the locals) and Dryopis or Dryopida (known as Chorio to the locals). Both villages are characterised by steep, winding streets, often stepped, which are often too narrow for cars. The architectural styles of both villages are slightly different from each. Both are pretty but Chora's houses are mainly flat-roofed, typical of the Cyclades, while Chorio's houses tend to have sloping roofs. An interesting attraction in Chora is its large Greek Orthodox Church.
The island can be reached by ferry from Piraeus and Lavrio. The crossing from Piraeus takes around 3 hours by conventional ferry and 1 hour by high speed ferry. The crossing from Lavrio takes roughly 2 hours. Kythnos is also connected by ferry to the islands of Serifos, Sifnos, Milos, Santorini, Sikinos, Folegandros and Kea.
The Greek island of Sifnos is located in the western end of the Cyclades group of islands and is typical of the islands of the Cyclades with its traditional architecture, lovely calm beaches, pretty tavernas and hills. The island's south coast is where most of its popular beaches are located and many have soft sand, crystal clear water and good facilities. A popular attraction on the island is the lovely Monastery of Chrissopighi which is the island's protector. The most picturesque village on the island is Kastro, which is surrounded on three sides by views of the Aegean Sea, and is characterised by narrow streets, stone built houses and beautiful views of the sea. The village can trace its history back 4,000 years with evidence of its past visible in many places and includes part of its defensive wall which was built in around 800 BC.
The island's port is located in the town of Kamares. During the summer months there are daily services of both high speed and conventional ferries to the island. Ferries connect Sifnos with Piraeus and to the other Cycladic islands such as Serifos, Folegandros, Kythnos, Milos, Ios, Santorini and Crete.
