Ortari is a mountain located within near the northwest of the city of Kymi on the island of Euboea. The northern sides form a spectacular geological terrain, with nearly vertical slopes, dropping to the Aegean Sea. The dense vegetation just reaches the sea. At some points at the base of the cliffs are formed small beaches. The highest peak has an altitude of 876m and is located just above the thalassa. When the weather is clear, especially in the winter, visitors are able to see over a distance of 100 nautical miles many Aegean islands. Also visible are the three peninsulas of Chalkidiki, the main Mount Athos, mountains Olympus, Pelion, and many of the peaks of Central Greece.
