It is the largest village of the island, where you will see the harbour, the Popular Art Museum, the Archaeological Museum, the Palaeokastron (Old Castle) (6th - 4th century B.C.) and the Venetian Castle with the church of Panagia Spelianie. Close to Mandraki is one of the most beautiful beaches of the island, Hohlaki with impressive volcanic black pebbles, which attracts many visitors. You can swim in the small sandy beach of Agios Savvas, very close to the city. Boats go to the near by small island Giali, northwest of Nisyros with stunning beaches. In Giali pumice is excavated.
