This is the standard and best-known mountaineering route to Rheinwaldhorn. It is a glacier and snow climb rather than a hiking path, and normally starts from Capanna Adula CAS. The route is generally considered moderate in alpine difficulty, but conditions on the glacier and upper slopes can vary significantly. Crevasse exposure and snow stability are the main objective hazards. In late season, the route can become more broken and require more careful route-finding. It is the classic ascent described in Swiss alpine guidebooks for the peak.
