Kutelka Reserve lies in the Sinite Kamani (Blue Rocks) Nature Park above Sliven and is named after Kutelka peak (1,084 m) within its bounds. It was declared in 1983 and covers 685.98 ha.
The reserve protects an original beech forest of Moesian beech, more than a century old. The largest habitat is thermophilous beech forest, and the oldest stands are in the northern and higher parts.
