The south ridge is a documented alpine route on Zimba and is more of a mountaineering line than a walk. It is characterized by exposed ridge climbing on solid but broken rock. The route requires sure-footedness and comfort on steep alpine terrain. Depending on conditions, some sections may feel more difficult than the nominal grade suggests. It is best attempted in dry conditions, as loose or wet rock increases objective hazard. The route is usually described in standard alpine guidebooks for the Rätikon.
