Mostly spruce forest with mixed runability. In general the runability is good, but reduces in some parts of the terrain where undergrowth and fallen trees limit the running speed. Many differently sized marshes in the forest. Even in the marshes the running speed differs from good to limited in areas with undergrowth. Land forms are mostly distinctive and rich in details. Generally, there are only few paths and roads. Maximum height difference is 20 meters.
