This red has two routes which go in opposite directions. The first leads on from Les Chottes in Greppon Blanc down to the Drus button lift above Veysonnaz. In reverse, it turns left off Les Crêtes in Thon and heads back towards Greppon Blanc. 

It’s a collection of wide pistes, forest and high mountain paths to help you get across from one valley to another. But it’s a fun run to do even if you’re not heading anywhere in particular with only a couple of short steep sections.
