The Greek island of Kea is located in the Aegean Sea and is one of the Cycladese group of islands. Kea is roughly 20 km from Cape Sounio and 60 km to the south east of Athens, the Greek capital. The island is not particularly large, measuring 9 km wide and 19 km long, and its main villages are Korissa and Vourkari. One of the most popular visitor attractions on the island is the pretty port of Korissia, which is surrounded by white washed houses with colourful roofs, the enamel factory, winding cobbled alleys and picturesque churches. Visitors will often see caiques and fishing boats in the harbour.
The island's crystal clear waters make it a popular destination for scuba divers. The island's waters have excellent visibility, is rich in marine life and is great for wall diving. Some of the most popular dive sites around the island are the wreck of the steamship Patris which sank in 1868 and also the famous wreck of HMS Britannic, the sister ship of the Titanic, which is located around 1.5 nautical miles offshore. The latter is popular with Tec divers as the wreck is at a depth of around 120 meters.
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.
