Gyali (Yiali) is a small volcanic island between the south coast of Kos and Nisyros in the Dodecanese. Two explosions created it after the formation of Nisyros. The first explosion, which created the southwestern part of the island, deposited over 160 meters of pumice into the shallow sea.

The northeastern part of the island consists of obsidian lava domes and perlite. In Greek, “Gyali” means glass. Pumice stone deposits are mined in vast quantities. A narrow isthmus and beach made of modern reef sediments connect the island’s two parts. Approximately 16 people live on the island.

Gyali is not an island to stay on for a whole vacation but rather an island worth stopping by for a day. While on Gyali, don’t miss the beautiful beach Agios Antonios, between Nisyros and Gyali.


The climate in Gyali is similar to the other Dodecanese islands. It has the typical Mediterranean climate of hot, dry summer and a milder winter. The southern Dodecanese islands have warmer weather sooner than the north of the archipelago.

Average temperatures in May are about 65 to 72 degrees; in the peak of the summer, the temperature rises to the mid-90s.
