The holiday resort of Lenk lies at the very rear of the Simmen valley in a wide opening. Here, the Wildstrubel massif forms one of the most beautiful valley closures in the Alps, and the perfect setting for the varied Bernese Oberland walking and winter sports paradise with its many natural attractions.
Erosion has created an immense, pale yellow rock basin that is growing larger every year. It is well worth admiring this phenomenon of nature. The circular route follows the (mostly dry) bed of the Wildbach to the Bhutan Bridge and the Güetji viewing pulpit. Return to Susten along the other side of the trench.
