Cresta Sella is the south ridge of Lyskamm and a very beautiful and enjoyable climb. After about 2h approach from Gniffetti or Mantova hut we reach Naso del Lyskamm from where the actual ridge climb. At first a knife sharp snow ridge, then a mix of snow and rocky terrain offers variable climbing. After reaching the summit, the normal route down the east ridge of Lyskamm descends to Col de Lys. Being a round trip with constantly changing views and terrain makes it a great mountaineering route.
