Kleine Oker

Kleine Oker is a mountain brook that winds through the Harz landscape between Clausthal-Zellerfeld and Altenau. The water flows clear and fresh over rocks and boulders, forming small cascades as it travels through dense forest and open hillsides.

The brook has been a vital water source for mining operations since the 16th century and helped shape the development of the region. Its water power and quality made it an essential element of the economy and settlement in the Harz Mountains.

The brook is woven into the daily landscape for residents of both communities and shapes how they relate to their natural surroundings. Its steady flow and sound accompany walkers through the forest and create a rhythm for encountering the mountains.

Multiple hiking trails follow the course of the brook and provide easy ways to explore the area. Most routes are well marked and range from easy to moderate difficulty, so visitors can choose based on their fitness level.

The brook is part of the larger Oker river system and flows consistently year-round because of the Harz's unique geological formations. This reliable water supply makes it a dependable water source in the heart of the mountain landscape.
