Koncheto

Koncheto is a name given to a knife-edge ridge in the Pirin Mountains in Bulgaria, at an elevation of approximately 2,810 metres, between the peaks Banski Suhodol and Kutelo. There are steep slopes on either side: the northwestern side is almost vertical and 300–400 metres deep, while the southwestern side is less steep but deeper. There is a steel cable stretched along the top of the ridge to help hikers across. It is said that some less experienced hikers go through Koncheto by saddling the ridge edge like a horse and slowly advancing, hence its name. It is not recommended for hikers with acrophobia.
