The beautiful Black Forest with its dark, densely-wooded hills is one of the most visited upland regions in Europe. In the southwestern corner of Germany and extending 160 kilometers from Pforzheim in the north to Waldshut on the High Rhine in the south, it's a hiker's heaven. On the west side, it descends steeply to the Rhine crossed by lush valleys, while on the east it slopes more gently down to the upper Neckar and Danube valleys. Popular spots include Germany's oldest ski area at Todtnau, the magnificent spa facilities of Baden-Baden, and the attractive resort of Bad Liebenzell. Other highlights include the spectacular Black Forest Railway centered on Triberg with its famous falls, and Triberg itself, home to the Black Forest Open Air Museum.
