Traverse of the Grandes Jorasses, Day 2 Map

This is a big day and getting to the summit of the Grandes Jorasses, via all the intricate ridge climbing, may not be the hardest part. The descent to the Boccalette Hut can be very troublesome, particularly later in the season. Before embarking on this two day route you need to be confident about this descent, by seeking recent local advice. If the hut is shut that may suggest conditions are far from ideal. I remember feeling very uncertain, looking down from the summit of the Grandes Jorasses, unable to see an obvious way through the labyrinth of crevasses. It took a long time!


The start is immediately technical and the rock climbing, facing NW, may have snow on it. It is slabby but tricky with a big pack, and I remember this initial section feeling the hardest of the whole route. Pointe Young at 3996m is very exposed at the top, as you traverse along to Pointe Marguerite. There are a number of route variations on this section, traversing on the S side of the ridge and missing out some of the towers. Once you get to Pointe Croz it is more straightforward. If time is short, or weather threatening, you can descend direct down the ridge from Pointe Whymper. But carrying on to Pointe Walker is clearly the ideal, as marked, then descend as for the separately described normal route on the Grandes Jorasses, to the Boccalette Hut. I descended the same day to the valley, but regretted the extra effort. Savour the mountain environment and do it in the morning.
