Plan the return journey

Descent

From Sunny Side, you can either hike down the unmaintained route or climb up steep grassy slopes. Then you drive with skis to the parking lot. On Dark Side, some of the descents are prepared; the topo also shows foot descents. For the other lines, please follow the return directions in the respective topo.

Ice formation and objective hazards

Safety and conditions

There is a risk of avalanches from the slopes above the icefalls. The Äbnet–Stäfelifall lies on the south side and receives sun from the end of January. Only ascend the Sunnetiger if the hanging cigar to the left of the second rope has already been broken off. The route receives sun approximately from 11:30 to 14:30.

Check before the tour current conditions in Engelberg, that SLF avalanche bulletin and the weather development. The seasonal timeframes and walk-through photos do not replace an up-to-date assessment.
