The Eckersprung (890 m above sea level), the source of the Ecker River, is located at a rest area right on the Goetheweg, which leads from the gatehouse up a gentle slope to the Brocken.

The Ecker River draws water from numerous streams in the moors below the Brocken—such as the Königsbach, the Morgendbrodsbach, and the Abbé—and then flows into the Eckertalsperre reservoir. After leaving the reservoir, it flows through the idyllic, partly deeply incised Eckertal valley and, in its lower course—which largely follows the state border between Saxony-Anhalt and Lower Saxony—empties into the Oker near the village of Wiedelah.
The stamp box is located in the refuge at the rest area. If you don’t want to follow the Goetheweg from Eckersprung to the Brocken, you can return to the Torfhaus via the Dreieckiger Pfahl HWN 168, the Hopfensäcke and the Abbegraben.
