From the Chäserrugg the hike leads past ibex herds and through karst fields near the Obersässhüttli (Obersäss Hut). After a uniform descent past several alps, one reaches Voralpsee, a lake surrounded by forests and rocks.
A hiking tour off the beaten track and "far from the madding crowd" in pristine, untouched nature, skirting one of the most beautiful mountain lakes.
Demanding, 5 - 6 hour hike.
Fir trees, up to 500 years old, flowers, butterflies, gentian and woodchucks (marmots): the valley of Avançon is home to a varied flora and fauna. It is highly likely that you will spot chamois and ibex .
