Fenêtre du Guil (Guillestre)
Hiking orcycling route along the old road Queyras, road called the Viste. Time (round-trip): 1 hour.
The scenic walk along route de la Viste (exit Guillestre towards Queyras) is "historic" because it crosses "the anticline nappe of Guil" described by alpine geologists in the 1950's. It is one of the first examples of the "thrust sheet" so characteristic of Briançon.
Information boards along the road and a panoramic platform at the end of the walk allow visitors to discover the chronology of the rocks and to understand the "anomaly" affecting them...
