Alonissos is a green, hilly island, covered with many pine forests and olive and grape orchards. The highest point on Alonissos is the Kouvouli (476 m), followed by the Geladias (456 m), the Tourkovigla (343 m), the Kalovoulos (355 m) and the Vouno (255 m). The island is known for its beautiful beaches, especially on the east side (including Chrisi Milia Kokkinokastro, Tzorzi Gialo and Steni-vala) and clear water. The 82 sandy, pebble and fine gravel beaches, which are nowhere long due to the rugged nature of the coastline, are surrounded by pine trees and beautiful rock formations. The west coast of Alonissos is much more rocky with steep cliffs in some places, and therefore has far fewer beaches. The seawater around Alonissos is known as the cleanest of the Aegean Sea.
