Safety classification
April–November per the official route listing. Valley-floor path, 8 km, 161 m ascent, ~2 h. Trümmelbach Falls open early April–early November only (9:00–17:00; Jul/Aug 8:30–18:00); the Staubbach Falls gallery is open May–October and closed in winter because of icefall. In winter the valley path can be icy and both waterfall galleries are shut — do not plan the full itinerary November–March. After storms the route can be blocked; check with the local information centre.
- ▲Rockfall and icefall at the cliff-base viewpoints — the Staubbach gallery closes October–May for this reason
