Safety and conditions

At pillar Zonk in sector Zonk, there is an explicit warning of the risk of collapse. Nameless is described there as partially crumbly. Freestanding in Trübsaal only rarely forms. The presence of individual bolts does not imply a confirmed, complete installation of all lines.

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.
