The Northwest Ridge of the Fletschhorn is the normal route from the Weissmies Hut and the first leg of the Fletschhorn - Lagginhorn Traverse which is included in "Walliser Alpen Die 100 schönsten Touren" by Michel Vaucher with Gaston Rebuffat. It is a varied ascent involving a dry glacier and perhaps a bit of rock scrambling (depending on the exact line and time of year) in the beginning followed by a glacier crossing and the ascent of a sweeping ridge above the famous North Face. The first ascent of this route was probably made in July of 1889 by J.D. James and Ambros Supersaxo.
The Weissmies Hut is 3 hours from Saas Grund or 1 h from the station Kreuzboden of the Hohsaas lift. One could also ride all the way to Hohsaas and walk downhill to the hut. A second hut page with photo (in Dutch): Weissmies Hut MAP On this, you can easily trace the route as described below. Click one time north to locate the Fletschhorn. See the main page for information on getting to Saas Grund.
A track leads from the hut east then north to a small dry portion of the Fletschorn Glacier located below the active icefall of the upper glacier. Cross the glacier trending north to the base of the slopes leading upward toward point 3527 on the Swiss Topo. These slopes have varying amounts of snow and scree depending on the time of year. A fairly good track exists in the scree when it is not snow covered. Otherwise take the easiest route to the ridge top. Follow the ridge top to its junction with the Grüebu Glacier. Make rising traverse across the Grüebu Glacier to the Northwest Ridge, then follow the ridge to the summit. Climbing on the route:
Basic glacier travel gear. No rock pro is needed.
