The Voie Soleil Levant, or Sunrise Pillar, is the classic and most ascended route on the SE face. It consists of roughly 18 pitches of enjoyable alpine rock climbing. Just very few (dubious) pegs are sticking, so prepare to climb every pitch using your own protection.
Although most of the rock of Mont Collon is of bad, and sometimes horrible quality, the SE face consists mostly of acceptable and sometimes good granite. However, this is only true as long as one stays on one of the numerous spurs of the face and not in the couloirs alongside.
The Voie Soleil Levant is an excellent and adventurous climb on good rock in a very alpine environment.
The route is can be reached in 1.5 h from the Bouquetins Bivouac (glacier and moraines).
The Bouquetins hut is a 4 h walk from Arolla (the closest village).
There are a camping, hotel, shops and a big parking lot.
Follow the spur. Go left and right of the first three towers. The Fourth (free standing) tower has to be climbed until halfway, on a slab that is difficult to protect, then traverse it on the right side. After this, the route becomes more like wall than a spur. Also the route finding becomes harder. Keep in mind that the end of the difficulties are at a ramp on the right side above you.
very few pegs. possibilities for own protection are good
