About Folegandros

Folegandros is a small, bare Cycladic island between Milos and Santorini, best known for Chora, a village of whitewashed houses perched above the sea. A path climbs to the church of Panagia on the ridge, and the coves of Agali and Katergo offer clear water for swimming. Ferries connect it with Milos, Santorini and Athens. May and June are mild and green, September and early October bring warm seas, and the island empties out through winter.
