The Erma Gorge is about 100 m (328 ft) long and about 5 m (16 ft) wide at the narrowest part. On both sides rise the cliff walls of peak Zhilav Kamak (The Tough Rock) in south and Tsarkvishteto (The Chapel) in north. It is located about 3 km from the city of Tran, in the province of Pernik, near the border with Serbia. On July 26, 1961 it was declared a National Monument in order to preserve its unique rock formations.
