The north face of Vihren is a well-known mountaineering objective and is significantly more serious than the normal hiking approaches. It involves steep, exposed alpine terrain with a more sustained climbing character than the south-side routes. Depending on conditions, snow and ice can be present for much of the season, increasing objective hazard. The line is suitable only for experienced climbers comfortable with route-finding and mixed mountain conditions. Rockfall and rapidly changing weather are important concerns. This is a genuine alpine route, not a trekking path.
