Görjeån stream meanders through a dramatic ravine landscape which it has created itself. Still today the area is being shaped through heavy erosion which makes trees fall into the stream, new sandbanks form and so-called oxbow lakes formed by being cut off when the stream breaks a new course for itself. The flowing water creates shallows that are constantly re-forming. The water of Görjeån is of good quality and of high natural values. Both quarters and beavers are found along Görjeån. In many places, the forest is verdant, with tall grass and flowers. The area is 8 square kilometres in size.
The reserve lies about 11 kilometres south of Vuollerim and is most easily reached from the north via the public road from Vuollerim.
