The restaurant is located at an altitude of 1,725 meters directly on the winter hiking trail and near the Crest Falla ski lifts. The large sun terrace offers a unique view across the Rhine Valley to the Signina mountain range.

A cozy mountain hut with very friendly staff. From the dining tables, you have a view of the large reservoir and the surrounding mountains. Overnight stays are available in small dormitories.

The hut has been recently renovated and is now even more comfortable. It's beautifully situated, surrounded by mountains and on the edge of the Greina Plain. You reach the hut via a new suspension bridge. Too exciting? You can also walk along the other side of the mountain.

At a similar altitude lies the Guraletschsee to the south and the Selvasee to the north. The three lakes are connected by hiking trails and can be reached from Zervreila or directly from Vals.
