The centre of the Bohemian Forest lies between Zwiesel in the west and Vimperk in the east. It is a low-relief plateau, which rises almost everywhere to above 1,000 m. Northwest, towards the Großer Falkenstein (1,315 m), the relief energy rises; on the far side of the Great Regen valley, this line continues, crest- or even arête-like into the Kunisch Mountains with the Seewand/Zwercheck. (up to 1,343 m) and Osser (up to 1,293 m), which are located directly on the German-Czech border. The lower-lying Fahrenberg (893 m) finally leads to the Hoher Bogen (up to 1,079 m) that descends into the Cham-Furth Depression.
