Kythnos (Thermia), a beautiful mountainous island between Kea and Serifos in the western Cyclades, attracts many visitors to its wild beauty and lovely beaches, particularly Athenians, on weekends. Due to its proximity to Athens, it has become a fashionable location for vacation homes. A sprawling coastline reveals hundreds of bays and coves. The aroma of oregano and thyme, windmills, and lonely lighthouses are dispersed throughout the countryside.


Places to see

  • Towns and villages. Chora (Messaria or Kythnos) and Driopida are the most traditional villages with stone houses and cobblestone streets that are winding and steep and too narrow for vehicular traffic. At the same time, Loutra and Merihas are hosts to tourist facilities. Loutra is famous for its thermal springs, which are supposed to have healing powers.
  • The Katafiki Cave in Driopida. Impressive stalactites and stalagmites provide an impressive experience. The cave was once a refuge from raids of pirates and other attackers and the site of an iron mine until 1939.
  • Healing springs in Loutra. Loutra is a popular resort town that attracts many visitors seeking a cure in the thermal springs.
  • Driopida. A small hamlet, far from the sea and strong summer winds. In ancient times Driopida was the capital of Kythnos. The two-story whitewashed houses have red-tiled roofs, an unusual architecture for the Cyclades.
  • Byzantine Museum.
  • Merihas. Merihas has a lively nightlife that attracts young locals and visitors. Besides numerous tavernas and cafes, it does have some hotels as well.
  • The archeological site of Vriokastro. Remnants of walls, temples, altars, and Roman buildings can be found here.
  • The Monastery of Panagia in Kanala, a small coastal village. The monastery attracts many pilgrims since it houses the icon of the Virgin Mary, believed to have healing powers.
  • The castle of Oria. See traces of a fortified acropolis along with remnants of the fortified town.

Things to do

  • Hike. The island offers an extensive network of trails that are often not well-marked but easy to follow. One of the most beautiful routes is the trail from Chora to Driopida, passing through amazing mountainous scenery. Another magnificent trail leads from the port village of Merihas to the lovely beach of Kolona.
  • Scuba dive. Caves, shipwrecks, ridges, and an enormous amount of richly colored fish can be seen at more than 30 dive sites. The most popular place for diving is Agios Sostis. A dive at the reef of Vouvokera will be interesting at greater depths, as is the Bay of Mamkos. Observe remnants of ancient vases lying on the bottom of the sea at Kseratis Agios.
  • Mountain Bike.
