I have just written up a trip report on the Tour du Mont Blanc that my husband and I walked in July 2006, with 20 photos. It might be of interest if you are thinking of walking this route - which we love so much we've now done it a full three times and in part many times more than that. Sometimes we finish ahead of schedule and start all over again, not actually because we lack imagination, but because it's just so beautiful that it seems like the very best way to spend the days we had left for mishap / emergencies / illness or whatever (and it seems daft to waste time going somewhere else when we we are is so magnificent). This trip was in July, and very crowded. We did it in early June where we had deep snow most of the way and only encountered eight other people (who were all travelling together with a guide) the whole length of the route. The third time was mid June with medium snow, lots of flowers lower down, and not too many people.
Mostly my blogsite is about climbing Tassie mountains, but I was too sick to go up anything this week, so used the gap to begin writing up some of our overseas ventures. This was the first.
