The trail of Petko and the forest inhabitants – Pehchevo Adventure is actually an educational project for students and tourists in terms of the protection of the biodiversity, through education and implementation of practices from the non-formal education. The trail begins from the location of the Educational Centre in the village of Negrevo, Pehchevo (which is currently under construction) and it ends near the place where the carnivorous plant Venus flytrap grows.

On this trail can be found educational boards containing information about the characteristics of certain species from the Bregalnica region. Through outdoor learning, all participants can get closer to topics from the biodiversity, the environment and the nature areas, as well as their protection.
