For me, one of the most idyllic stamping points for the Harz hiking pin. The path along the “Allee der Bäume” is recommended. Here you walk through the Grumbachtal: one of the last completely forested valleys in the Upper Harz. An easy path to walk, the Grumbach gently babbles along and there is dense coniferous forest everywhere. Just before the Grumbach pond, you pass the Grumbach waterfall and then suddenly the Grumbach pond, surrounded by forest, lies quiet and calm in front of you - it doesn't get more Harz idyll than this! The reflection of the trees in the water is also beautiful! By the way, the stamping point is not only necessary for the HWN, but also for the Wildemann hiking pin!

Wonderful panorama 🌊💙 Stamp office of the HWN 110♟️ Beautiful shelter with benches available to really enjoy what is offered here - simply wonderful ❣️🤗📸 Built in 1969, the Granetalsperre 🌊 is the youngest of the Harz reservoirs. Because the Grane river does not carry enough water for the 3 km long lake, an approx. 7.4 km long tunnel to the Oker was dug below the Okertalsperre. 😲
