About this site
Alonnisos is one of the Sporades islands in the western Aegean, off the coast of Thessaly in central Greece, and its shoreline is marked by limestone cliffs and inlets typical of the group. The island sits within the Alonnisos Marine Park, an area established to protect the surrounding waters. Dive sites named for caves along this coast typically make use of the rocky formations and small underwater openings found along these cliffs.
