Mountain hiking trail from Nessleren/Underberg. A very rewarding ascent through the valley floor of the Saxettal over flower-rich alpine pastures to the flank of the Sulegg and over the saddle between Bällenalp and Sylertal to one of the most beautiful viewpoints in the Jungfrau region, Bällehöchst. The descent past the dreamy Sulsseewli with its magnificent reflection is equally impressive. A forest hike down to Isenfluh, located on a scenic terrace, concludes this varied route. At the beginning, 1 km of hard surface.
