Berlin does not end in one clean cut here. It fades layer by layer: south through Britz and Buckow to Großziethen, then out past the S-Bahn edge and on towards Zossen. Wünsdorf marks the first proper shift, with less city, more forest and longer straight roads. After Baruth, the route turns more rural, passing Klasdorf and Golßen before Luckau. From there it runs through villages and open fields towards Crinitz. Finsterwalde arrives after 113 flat but serious kilometres.
