Hiking
A geological curiosity is the Nebelloch, a deep cave above the Kupfertal valley southwest of Niedernhall. The cave is about 12 feet long. Locally, it's known as the "warm hole." In winter, warm vapors rise from it. As the snow melts all around, nearby woodcutters dangle their legs in the opening to warm them during periods of extreme cold.

The best time to visit is during the colder months. If you stand on the ground near the opening, you can feel the warm breeze.
