Mountainous and rocky, Folegandros is, in fact, a Phoeniciann word meaning rocky.
The island has several nice beaches. In the South, sandy Livadi Beach is a short walk from the port. The island's best beach, Katergo Beach can be reached from Livadi by walking across the hills. It's on the island bus route as well. There's a picturesque islet in the bay at Katergo, and a long sandy strip of beach.
Halfway between Hora and Ano Meria lies sandy Angali Beach with several taverns, a campground and shady pine trees. The beach is at the bottom of a steep path with donkeys availble to carry one down for a fee. Nearby the 2 nudists beaches of Aghios Nikolaos and Fira are also within walking distance but easier to reach by water-taxi from Karavostassi Port. There is swimming right in Karavostassi, also.
The beaches on the north coast are accessible only by boat.
