Elasa is the easternmost territory of the province of Sitia and the entire Crete region, as it is located about 3 nautical miles east of Cape Sidero. It spans an area of 1.75 square kilometers, while the highest altitude is 75 meters.
Its terrain consists mainly of hard limestone and its entire coastline is rocky, with the exception of the tiny bay in the center of the island, next to the island shelter. The internal part of the isle hosts low vegetation, made of phrygana and low shrubs. Elasa is a protected area and the high distance from the nearest cities has fortunately kept the place virgin.
