Chuklite
The Chukli are located near Cherven Bryag, Pleven Region and are groups of rock pyramids formed among the limestones of the Mezdren and Kailash Formations in the canyon of the Rachene River. They are accessible only to pedestrians, and are accessible by dirt roads only in dry weather. There is no preserved tourist infrastructure in the area and the remoteness of the canyon from populated areas makes it a habitat for birds of prey.
