In reply to davidoldfart: It's called the Tour Tarentaise. All of the ski schools in Tignes and Val d'Isere offer it as a regular trip when in condition.
The first time I did it I was with a charming guide from Tignes called Pascale. When we stopped for lunch he told us what we would be doing for the rest of the day. His final words were, 'And then at the end of the day we descend to the village of Villaroger. There, if you like, you can have the village tart. It is very pleasant.' He was right, it was very pleasant.
