Agathonisi or Gaidaros (Donkey), is a favorite of many cruisers. It is a small island with about 150 inhabitants living in two villages: 125 in the Megalo Chorio (Big Village), and 25 in the Mikro Chorio (Small Village), its tallest point is 189 m above sea level. Its area, combined with neighboring islets, is 14.5 km2.
While Agathonisi belongs to the Dodecanese prefecture, most of its goods come from nearby Samos (only 15 nM to the N). It is an island out of the main tourist stream and it has many protected coves as well as a small but well sheltered harbour and ferry port, Ayios Yioryios.
