The Hexenloch Mill (, lit. "Witch's Hole Mill"), formerly the Dreistegen Mill (Dreistegenmühle), lies in the ravine-like Hexenloch (also sometimes called the Hexenloch valley, but not often by the locals) in the Black Forest in Germany between St. Märgen and Furtwangen in the parish of Furtwangen-Neukirch. It was built in 1825 and has been in the same family since 1839.Hexenlochmühle at www.hexenlochmuehle.de. Retrieved 2 Apr 2018.
It is the only mill in the Black Forest with two water wheels. In 1825, the part with the smaller water wheel was built as a nail smithy. Later, the part with the larger water wheel was built as a sawmill. Eventually the nail smithy was turned into a workshop for the clockmaking works.
The mill and restaurant are open daily all year round, with the exception for 2 weeks in March.
