Start early, usually from Monchjoch Hutte 3/4 hour glacier walk from Jungfraujoch station.
Staying overnight in the hut gives an ideal start time and place on the summit day. Allow 5-6 hours to Eiger summit from the Hut.
Leave the hut decending left to cross the glacier North, towards point 3680m then NW to the South Eigerjoch to gain your first view down to the green valleys.
Avoiding crevasses, join the ridge and follow NE then N to join the South ridge.
Depending on the state of the snowfall and weather, the ridge will have some rock and some ice/snow. All the usual crampon & axe gear is a must. Also a small selection of rock protection. I dont know what the average swiss guide etc takes, but rope is up to your own prefference.
If you have information about this route that doesn't pertain to any of the other sections, please add it here. I never finished this route....so PLEASE feel free to add anything or email me so i can add. Many thanks
