The Harz Witches' Trail (German: Harzer Hexenstieg) is a footpath, just under 100 km long, in Germany that runs from Osterode through the Harz mountains and over its highest peak, the Brocken, to Thale. It is a project by the Harz Transport Association and Harz Club and is part of the system of trails known as the Harzer Wandernadel.
The trail runs from Osterode via Lerbach to Buntenbock, which is in the borough of Clausthal-Zellerfeld and surrounded by the Upper Harz Ponds. The ponds are part of a cultural monument to the former mining industry of the Harz, known as the Upper Harz Water Regale and to which the Dyke Ditch belongs.
Following the Dyke Ditch, the path passes the Dam House as well as the Grabenhaus Rose which belongs to the town of Altenau. Passing the Förster Ludwig Platz and Naben Valley Waterfall the path reaches Torfhaus via the Steile Wand ("Steep Wall").
In Torfhaus the Witches' Trail splits into two routes. The main route runs along the Goethe Way to the Brocken, in places parallel to the Brocken Railway, and from there to Königshütte. An alternative route bypasses the Brocken and runs to other features of the Upper Harz Water Regale such as the Oderteich and the Rehberg Ditch. After passing Sankt Andreasberg and Braunlage this path rejoins the main route.
