Hike from the Grube Samson Mining Museum along the Rehberger Graben to the Oderteich pond.

Tip: Activate the audio guide mode in the app. At many points you will learn exciting details about the Upper Harz water management system around Sankt Andreasberg.

This hike from the Grube Samson Mining Museum in Sankt Andreasberg to the Oderteich pond is around 10 km long. It passes through the Upper Harz Water Management System, which is part of the UNESCO World Heritage in the Harz.

The water transport ditches and ponds were necessary to provide energy in the mines. The ore extracted underground had to be hoisted to the surface. Rainwater that seeped into the mine had to be pumped out of the galleries. The energy was provided by giant water wheels. They needed a lot of water all year round. The water was collected in the storage ponds and flowed to the water wheels through the ditches.

On this hike you will find out how people around Sankt Andreasberg used the water for mining. And how the water is still used to produce electricity.

On the way you will find various signboards with information about the Upper Harz Water Management System.
