Deffeyes Refuge and Col Passo Alto

From the car park at the bar in La Joux, take the Alta Via 2 route, AV2. Go past the crossroads with the itineraries that lead to the three waterfalls on the Ruitor, and when you come to another crossroad, continue along AV2, ignoring route 8 on the right, and head for the lakes of Bella Comba. After a section on level ground at Alpe Glacier and the lakes of the same name, the path steeply gains altitude, climbing to the pasture of Ruitor and lastly to the Deffeyes refuge. From here, continue along the same itinerary, crossing grassy slopes and stone terrain until you come to Col Passo Alto.
