In fact it's just down south 3hrs by car from here. AND I was at the bottom of Mont Aiguille early June 2010 for 1 week of walking west from there, but the group wanted an easy start for the first day. I should have come one day earlier to see that sight, amazing. But then, even from the bottom, Mont Aiguille is awesome, litterally.
Very true. Oddly enough, June 2010 was when I was there too!
I stayed in Die and also walked in the area south of the Vassieux plateau and the Col de la Bataille. It was obscenely hot the week we were there though. Not much fun below 2,000m
