Climbed with Jan. When we arrived at the start of the route, we had to wait our turn because some other climbers got there just before we did. And by the time we started, more people were waiting. Still, once on the route it didn't feel crowded at all. No bottlenecks or holdups. It was a really enjoyable climb.
Climbed it somewhere in July 2009. Crowded but nice climbing, especially as my first alpine climb in 20 years...
climbed in Aug. 2009 - a very nice climb but very crowded (added a image showing several climbers in the traverse)
Very nice route in very good weather conditions. Excellent climbing. The better weather the more crowded.
Beautiful route, but very crowded and in some passages very polished. Start early in the morning (or climb it in the afternoon...)
