The change from Østmarka to Sørmarka takes place at the lake Langen. Østmarka is marked by its location on top of basement rock (more than 1 billion years old) containing easy-to-see folds that make up valleys and hills in the north-south direction. For this reason the terrain has a lot of hills, no matter where one goes.
