NB
The microlight flights are advertised quite widely around Tignes. One of the two big ski schools (either ESF or Evolution) also promotes them.
It's actually a one-man band. There's no advantage in trying to booking direct. He flies from the altiport above Val Claret. You just go up the 'Tichot' chairlift and it's about 500m on your left - very easy.
The guy was very friendly, although we quickly established that my French was a lot better than his English(!). It seemed to me that the price came down a little when we established I was a fellow aviator
I ended up paying E60 for 35 minutes I think. Not cheap by microlight standards, but worth every cent.
I'll try to post a pic of the 'altiport' later...
