Dark green, impenetrable forests cover a landscape with secluded valleys and rugged mountain ridges. 2.000 rivers and streams dig deep into the underground and transport their water into reservoirs or "Germany's Wild Amazon", the Wupper. These forests and rivers, together with heath-lands and moors, are home to a diverse fauna. Martens, badgers, wild boars, hares, roe deer, red deer and wild boars, even black grouse and hazel deer find shelter in these parts. Wolves have also have a dominant presence, not to mention those who live underground, such as lizards, bats, and snakes. Accompany us on a journey where we explore every corner of this rugged land. Climb underground into the Bergisches Land, through the vast hidden cave systems that sprawl far beneath the forests. There is also much to be discovered in the water, dive with us in crystal clear streams and rivers with their diverse flora and fauna.
