Flueseeli - Tierbergsattel - Iffigenalp

The route description from Simmenfälle to Flueseeli can be read here.

Flueseeli lies amid towering rock faces to the south and an open view to the north towards Lenk. The path ascends once more to the Rezligletscherseeli. The stream here is crossed by a bridge. Through the Tierberg, step by step, you go through the rocky area towards the Tierbergsattel, the highest point. Once at the level of the saddle, there is a clear view of the path behind you as well as on the other side of the saddle towards the Rawilseeleni. And the view can wander much further over the Rawil pass and the Plan des Roses plain towards Valais.

Now it is only downhill. Past the Rawilseeleni, the path from the Blattihütte leads somewhat exposed along a steep rock wall. Here the path has been blasted into the rock, and where necessary, fixed cables provide more safety. It is also worth stopping and enjoying the view into the Iffigtal. Once arrived below, the Berghaus Iffigenalp is an excellent place for a stop at the end of the route.

From here you can take the bus to Lenk or continue on foot.
