Natural reserve Vučak is located in the northwestern part of the park, in the area of the spa Kopaonik, on the southwest side of the Vučak peak. It covers an area of 62.02 ha. The basic value is the forest community of spruce and fir, which is especially interesting because fir gives the indicator significance of a particular spruce growing above its vertical belt (1,550-1,750 m). The concept of protection relates to the conservation community as a whole.
