Like the neighbouring reserve Cisy, it protects the beautiful tertiary relic that yew is. There are 462 yew trees on the area of 95 ha. They are accompanied by numerous pines, beeches, firs and oaks, and in the undergrowth you can find Aposeris foetida, a protected species of eastern Carpathians flora. Other protected species of plants include hard-fern, common polypody, northern firmoss and violet helleborine.

A visit to the reserve is facilitated by an educational trail with thematic boards and a gazebo to rest in after the hike.
