A top-class shaft hike awaits you on this extensive, 20-kilometer tour from the banks of the picturesque Frauenau drinking water reservoir. Discover the open spaces of the high pastures, which stand in wonderful contrast to the dense sea of forests of the Bavarian Forest National Park.You start at the parking lot for the drinking water reservoir and can quickly fill up your water bottle here. You walk leisurely on level ground along the reservoir. After about five kilometers, your calves get more to do, because it goes up to the Hoch- and Almschachten.The open mountain meadow landscape offers you a great view of the highest mountains of the Bavarian Forest. In the past and in some cases until today these open areas were and are grazed. Again and again you see single, ancient trees on the lush meadows: shady resting places for grazing animals and at the same time a great photo opportunity. Up here you will also find one or the other promising bench and refuge for your snack.The way back to the starting point takes you over soft forest paths and to the Lost Schachtenbach, which joins other small streams on the way down to the valley. It goes downhill slowly until you get back to the parking lot.
