From Unterwasser or Chüeboden (1035m a.s.l.), follow the signs of the summer- hiking-trail. To Thurwis, Chlingen. Arbitrary route towards N. Between Spitzbergli and the cliffs of Gir. Finally turn NE to E. Dismount Skies to gain access to the couloir between Girenspitz on the left and Säntis-summit on the right (100m, 35-40°). At the col (P.2397) there is an option to get to the summit via "Himmelsleiter" (SSE).
From the col, (P.2397) turn E. There might be a small cornice (1.5-2m, Feb. 2015). Descent via Blauschnee down to 1920m a.s.l.
Turn S till you reach the col "Wagenlücke" (P.2075).
Ski down the slope towards S till you reach the valley floor. Here turn E and follow the valley until you reach Meglisalp (P.1517).
Turn S towards Spitzigstein, then SW towards col Rotsteinpass (P.2122).
Follow the valley. When there is bad visibility, beware of the cliffs, particularly around Flis-Schafboden (P.1729). Here better stay at the left flank. Some slopes ~35°! Back to Unterwasser.
