Saos Mountain is the highest mount among the islands of the Aegean Sea (except for Crete) with an elevation of 1.611 meters from the sea level. Another common name for the mountain is "Fegari" that literally in Greek means "moon". Every August the mountaineering club of the island organizes a climbing on the top of the mountain Saos, usually around the days of the full moon.
The very first feeling of each visitor of Samothraki is the dominance of the natural environment. The north part of the island is full of olive trees, oak trees, chestnut trees, plane trees, and maples. In the southern part of the island, there are olive trees and a plain of 5.000 acres which is used by local farmers. The most common bushes of the island are myrtles, wild roses, wild arbors, heathers and local shrubs called tsikoudies.
Samothraki is full of springs, creeks, and small rivers that flow through the Saos Mountain and end up in the sea. On the island, there are 16 different types of animal habitats and birds. During the spring and autumn, many migratory birds use the island as an intermediate stop on their journey. The seal Monachus Monachus finds refuge here since Samothraki has countless underwater caves and plenty of fish.
