SENTIERI DEL LYS
TREKKING IN AOSTA VALLEY FROM THE VINEYARDS TO MONTE ROSA ...
Sentieri del Lys are trekking trails that start out from the vineyards of the talweg of Pont-St-Martin, and go up to the glaciers of Monte Rosa, and end up in Staffal. It is medium-difficulty trekking with some exposed, but well equipped sections. The route can be used from May to October.
For the sections in higher altitudes, the best period is late June-mid September.
