I did this with a group in Aug. 2000. We had a fabulous trip with really great weather. The tour was run by Exodus Travel which is a UK company, but I think we heard about it from GAP in this country. People were from all over…most were Brits…but even from Australia, Canada, Ireland, etc. We started from Chamonix and walked around the massif. There was a separate camping group which we would see as they batted by us on the trail. I much preferred the fixed base accommodations with the buses bringing our luggage on to the next place…sometimes we would stay a few days at one place which was welcomed.
There are a number of ways to take the tour, I guess is what I’m trying to say. You should have no trouble finding the one which will suit you. Happy Trails!
