Peeshti Skali Reserve, Nature reserve in Tazha, Bulgaria

Peeshti Skali Reserve is a nature reserve in the Balkan Mountains near Tazha, Bulgaria, covered mostly by dense beech forests growing on steep slopes. The area also features rocky outcrops on the eastern side and provides habitat for bears, wolves, red deer, and golden and imperial eagles.

The reserve was declared on 11 July 1979 by Order No. 502 of the Committee for Environmental Protection at the Council of Ministers, covering 1465.7 hectares. Its creation was backed by the Institute of Ecology of the Bulgarian Academy of Sciences, and approving it was the new committee's first decision. The original proposal covered over 2000 hectares plus a buffer zone of more than 1300 hectares, later reduced.

The reserve's name was chosen by the conservationist Zheko Spiridonov because the rock formations in the eastern part of the Kalofer Mountains emit an unusual sound in strong wind. The name means Singing Rocks.

The terrain is steep in many parts, so solid footwear is strongly recommended before heading out on the trails. Starting early in the morning gives you a better chance of seeing wildlife before the day gets busier.

The reserve covers the entire catchment basin of the Rositsa, the largest left tributary of the Yantra, and also takes in parts of the land of the villages of Stokite and Kravenik in Sevlievo municipality. Its name was chosen by the conservationist Zheko Spiridonov.
