Morské oko (Sea Eye)

The picturesque, natural lake Morské oko (Sea Eye), called Great Vihorlat Lake in the past, and located in the deep beech forests of the Vihorlat Mountains is a reminder of a volcanic activity of the mountains, and is unparalleled among the volcanic mountains in Europe!

The formation of the lake Morské oko falls within a period of volcanic activity in the region. A massive landslide on the eastern slopes of Motrogon and Jedlinka blocked the valley of the brook Okna, and behind this barrier a natural lake arose. Morské oko is situated at an altitude of 618 m (2,027 ft). Its length is about 750 m (820 yd), depth is 25-28 m (82-88 ft), and is fed by 6 streams and several periodic flows. The excess water from the lake is lead away by the brook Okna.

There is a path leading around the lake which line its shores, and takes about an hour to walk. Visitors can choose a challenging 4 km (2.5 km) route with an elevation of 400 m (1,312 ft) to Snina Rock. This trip is rewarded by a spectacular view on the landscape of the valley of Cirocha, Vihorlat forests (Vihorlatské lesy) and Východoslovenská nížina (Eastern Slovakian Lowland).
