Kovaruv Mill
A small protected area, only 0.3 hectares in size, lies near the former Kovaruv Mill, an old slate quarry, on the left-hand bank of the River Oleska some 400 m from the church in Kostalov.
It includes rock outcrops and tors on a hillside beyond the mill which are some 2 m high and consist of settled rocks of the Lower Permian era, especially green-grey siltstones, arcoses and bituminous claystones. It is an important regional paleontological and stratigraphic site where several species of amphibians, sharks and Acanthodii vertebrates have been identified. The dark-grey to black siltstones and calcareous claystones in thin layers or ribbon structure contain remains of plants and animals.
The site has a special conservation status.
Go from Harrachov to Zacler or in the opposite direction, for a three-day trip or for a whole week. Enjoy the pure nature, the warmth of the mountain chalets and the sky full of stars.
