The Greek island of Sifnos is one of the Cyclades islands, and lies between the island of Serifos and the island of Milos. It is located to the west of Delos and Paros and around 130 km from Port of Piraeus on the Greek mainland. The island's capital is Apollonia, sometimes called Hora, and was built over three hills in the centre of the island in the shape of an amphitheatre. The town is characterised by its whitewashed houses in the typical Cycladic architectural style. The island's Folklore Museum is based in Apollonia, in Hiroon Square - which means Square of Heroes. One of the most popular visitor attractions on the island is the medieval castle located around 3.5 km from Apollonia. It was built on top of the island's ancient capital and still has the original characteristics of a Venetian fortification. It was established by the Da Corogna Dynasty in around 1635.
The town of Kamares is home to the island's port and during the summer there are ferry services operating to Piraeus, to other Cycladic islands like Serifos, Folegandros, Kythnos, Ios, Santorini and also to Crete.
Kythnos is a Greek island that is located very close to Attica and is part of the Cyclades group of islands. The island, sometimes called Thermia because of the thermal springs on the island, is one of the lesser visited islands of the Cyclades but is popular with visitors because of its thermal springs. There is a modern spa located in Loutra, with two hot springs in the area. The spring of Ayio Anargyroi and the spring of Caucasus, where the temperature of the water reaches 52C, are famous for their therapeutic effects and have been since ancient times.
The island's harbour is located at Merihas and the island's capital is called Hora and are both located in the north of the island. In the south, only the areas by the bay of Ayios Dimitrios and Panayia Canála are inhabited. This is where a famous monastery is located within a pine forest.
Ferry services from Kythnos depart to the Port of Piraeus or to the port of Lavrio. The crossing to Piraeus takes approximately 3 hours by conventional ferry and approximately one hour by high speed ferry. The crossing time to Lavrio takes about 2 hours.
