From the Tilisunahütte, follow the signpost towards Partnun (1.5 hrs). You go over the Tilisunafürggeli and mostly follow a meadow path up to the start of the family via ferrata slightly above the Partnunsee.
The via ferrata is designed for children and families and is therefore never more difficult than A/B.
The descent takes place on a marked hiking trail. After about 15 minutes, you are back at the start. On hot summer days, a short detour to the Partnunsee can be made, which can be reached by a short path. Then you return on the same route back to the Tilisunahütte.
