View of the mountain Gantrisch (2'175 m/7'136 ft). You can walk up to its peak in summer. Not sure if that's possible in winter.
During the winter the trails around the Oeschinensee (1'578 m/5'177 ft) are buried under metres of snow. Leaving the safety of the groomed paths would have been too dangerous because the threat of avalanches was ever present. On that day I saw two avalanches. Small ones though, but still impressive and scary.
