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.
The Greek island of Ios is part of the Cyclades group of islands and lies in the Aegean Sea between the islands of Santorini and Naxos. The island has a popular night economy, lovely beaches and a number of historical monuments which are popular with visitors. The island has been popular with tourists from around the world for many years and is definitely one of the most popular of the Cyclades islands. Chora is a typical Greek village on the island with traditional whitewashed buildings, winding streets and many colourful flowers. However, at night the sleepy village comes alive with many places to socialise.
Around the island there are many beaches with soft white sand just waiting to be explored, all of which are blessed with crystal clear waters. Perhaps the island's most popular beach is Mylopotas which is lined with bars, restaurants and places to hire water sport related equipment, and is over 1 km long. However, if you require a more secluded beach experience then Valmas or Kolitsani beaches are a good choice.
