Upper Bavarian Forest Nature Park

The Upper Bavarian Forest Nature Park (German: Naturpark Oberer Bayerischer Wald) covers an area of 1,796 km2 and is thus one of the largest nature parks in the German state of Bavaria.

Its highest summits are the Großer Osser (1,293 m), Hoher Bogen (1,079 m), Kaitersberg (1,133 m), Enzian (1,285 m), Schwarzeck (1,238 m), Zwercheck (1,333 m) and Kleiner Arber (1,384 m).

The mica schist on the Osser and the chalk transgression in the Obertrübenbach Quarry are among Bavaria's most attractive geotopes.

In addition to the dominant crystalline bedrock of granite and gneiss there are various sedimentary layers, siliceous and calcareous rocks, ancient limestones, mica schists and, in the geological feature of the 150-kilometre-long Pfahl ridge, quartzite and slate, which in places form rock pinnacles and towers.

For bird lovers, the Regentalaue nature reserve west of Cham with the Rötelseeweiher ponds offers good opportunities for observation.
