Located in the Cyclades group of islands is the Greek island of Thirasia, or Therasia, and lies in the Aegean Sea to the north west of Nea Kameni, a small island formed in recent centuries following volcanic activity. Located next to the island's small harbour is a pebble beach, which is the island's only beach. The only track of the island will take you to the church of Agia Irini which is said to have given Santorini its current name (Santa Irini - Santorini).
The Cyclades are an island group in the Aegean Sea, south east of mainland Greece and a former administrative prefecture of Greece. They are one of the island groups which constitute the Aegean archipelago. The name refers to the islands around the sacred island of Delos. The Cyclades is where the native Greek breed of cat (the Aegean cat) originated.
Visitors usually get to the island by boat as a part of a volcano trip that first gets you to Nea Kameni for a visit to the crater of the volcano then at the hot springs of Palaia Kameni for swimming and then to Thirasia for a few minutes before they head to Oia for the sunset.
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.
