Geologically and geomorphologically, the Bavarian Forest is part of the Bohemian Forest - the highest of the truncated highlands of the Bohemian Massif. The area along the Czech border has been designated as the Bavarian Forest National Park (240 km2), established in 1970 as the first national park in Germany. Another 3,008 km2 has been designated as the Bavarian Forest Nature Park, established 1967, and another 1,738 km2 as the Upper Bavarian Forest Nature Park, established in 1965. The Bavarian Forest is a remnant of the Hercynian Forest that stretched across southern Germania in Roman times. It is the largest protected forest area in central Europe.
