I've done this route several times, lots of fun! Not difficult, great climb if you just want to be in the mountains or to get acclimatized. Did get swarmed by a bus tour of tourists with their cameras as I hurled myself over the railing at Aiguille du Midi. I smiled for them.
Great day out, but found the route very boring. I think the think spring snow made it so we could walk right by the tricky rock bits. Some friends did it in summer and said it was really difficult, but we barely needed to belay anything.
Quite nice to end up directly at a cafe, although ambience is of climbing at a crowded ski lift station. Fortunately, in May, there were maybe 5 on the route all day.
"Got tight last night on absinthe and did knife tricks. Great success shooting the knife into the piano. The woodworms are so bad and eat hell out of all furniture that you can always claim the woodworms did it."
