did the grands mulets route on june 30th 08. well worth doing as the glacial scenery from the boissons to the col du dome is fantastic. deep snow on the grand plateau was hell. from the col follow the normal route to the summit. one of us really suffered from the altitude but he kept going. his exhaustion and blurred vision made for a tense descent to the aig midi. they say you can tell how big a mountain is when your descending, well mont blanc is big. its a big summit day [approx 1800mtrs] but keep in mind the grands mulets route.
