To climb the Eiger’s Mittellegi Ridge or the North Face route you need to be an experienced alpine climber on rock, snow and ice, physically fit, have strong mental stamina, and be capable of strenuous exercise for the entire duration of the chosen itinerary. Multi-pitch climbing rope skills, including belaying and lead climbing are essential. On some days, you will be climbing for 10-15 hours a day over technical terrain, which requires full focus and confidence.
