The Greek island of Serifos is located in the Cyclades group of islands and lies in the Aegean Sea to the south of Kythnos and to the north west of Sifnos. It is also around 170 km from the port of Piraeus. Greek mythology has it that the island is where Danae and her infant son, Perseus, were washed ashore after her father Acrisius set them adrift at sea in a wooden chest. When Perseus returned to the island with the head of the Gorgon Medusa, he turned Polydektes, the King of Serifos, into stone as punishment for the King's attempt to marry his mother by force.
Home to the island's port is the town of Livadi and is the main centre of tourism on the island. There are many restaurants, cafes bars and clubs in the town and is where most hotels are located. The town's beach is long and sandy and has crystal clear water. During the summer, many of sailing boats and yachts can be found anchored in the calm waters of this naturally protected bay.
The island is accessed by conventional and high speed ferries. During the summer months, there are ferries that connect Serifos with other nearby islands, such as Sifnos, Naxos, Paros, Santorini and Kythnos.
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. Kythnos is also connected by sea with the islands of Serifos, Sifnos, Milos, Santorini, Sikinos, Folegandros and Kea.
