I did north (highest) summit, a pleasant easy climb, excellent rock on the ridge
Solo on the summit
A very nice route on this pillar (D / IV).
A good warm-up for tougher climbs in the area (on the South Face of La Meije for example).
A few pitons are on the way. It gives an idea of the path and a little protection. Friends are recommanded.
Once on top follow the north ridge to reach the Col du Replat.
A fairly easy class III ascent.
2h30/3h to reach the start of the route. That year there was no snow left anywhere, quite tiring to walk on scree.
The ridge itself is very nice to climb.
Descent via Col du Replat.
