About Karpathos

Karpathos is a long, mountainous island in the Dodecanese between Rhodes and Kasos, where the village of Olympos keeps its own dialect and customs high on the northern slopes. Pigadia is the main port, Diafani serves the north, and Apella and Kyra Panagia are among the best known beaches. Strong summer winds make the island popular with windsurfers, and boats cross to the islet of Saria. May, June, September and October are warm with manageable winds, while winter is quiet.
