The Pollux N ridge is a classical, not so difficult, uncommon route to this summit. There are only a few parties climbing this route, so this is a very nice but because of the length of the route somewhat demanding way to climb this mountain. It's very much better then to start at the cable car to "kleines Matterhorn", following the crowds.
Start at the Monte Rosa Hütte. First follow the regular descent route of the hut down to the Grenzgletscher. When you reach the Grenzgletscher do not follow the marked path back to the Gornergrat. Instead turning left (W) and crossing the whole Grenzgletscher brings you to the base of the so called "Schwärze", a flank below the Pollux. Scrambling up the flank passing a nice lake leads to secondary glacier.
Follow this ice flank up to a snow saddle (3282 m) below the "kleiner Pollux" (3306 m), called "First Saddle". About 3 hours from Monte Rosa Hütte.
From the first snow saddle described above, the route in general follows the N-ridge of the Pollux. There are two other prominent snow saddels, the "Second Saddle" at 3630m (south below point 3660m) and the "Third Saddle" at 3810 m (south of point 3817m).
The crux is to reach the "Second Saddle". Between first and second saddle there is a steep, most time icy step (about 45°) with some crevasses. This step brings you up to the point 3660m and to the second saddle.
From there an easy snow crest leads up to the third saddle below the final part of the pollux summit. Following the snow and ice flank (sometimes BIG crevasses) brings you up to the summit.
It may take about 7 hours from the Monte Rosa Hütte to the summit.
Go down the regular route to Schwarztor (ZS-, 1,5 hours). From the Schwarztor there are several possibilities.
- go down SW to the Rifugio Guide della Val d'Ayas
- go to the Schwarztor-bivy (Bivacco Rossi e Volante, most time crowded)
- descent to the cable car (kleines Matterhorn), if you descent after the route to the cable car, the route will take about 11 hours.
ice axe, crampons, rope, 2-3 ice screws
