Hiking - Plan Vianney lake and the Périer gap

Of lesser dimensions and reputation than the Lauvitel, the Plan Vianney lake is however worth the detour, as is the panorama over the Valbonnais Oisans areas from the Périer gap. 

This demanding hike that starts on the family (and busy) trail that leads to the Lauvitel lake then leaves the crowd to follow a different footpath that is high and steep overlooking the Lauvitel lake followed by the Plan Vianny lake. It therefore has a wonderful view before getting to the Périer gap. 

It is preferable to make an early morning start as the path that leads to the Plan Vianney and then the gap is steep and exposed.
