The Höllental (English translation: Hell's Valley) in the Black Forest is a deep valley - in places like a gorge - in the state of Baden-Württemberg in Germany. The valley, which is about 9 kilometres long, is located in the southern part of the Southern Black Forest Nature Park about 18 km southeast of Freiburg im Breisgau between Hinterzarten and Buchenbach-Himmelreich. The Rotbach stream (also called Höllenbach in the upper Höllental) runs through the valley. "Hölle" is the German word for "hell". In the narrow, dark valley, travellers almost felt like moving underground.
