"Right at the foot of Fort Infernet, between pine forests and scree, along the cableway, is Lieutenant Miguet's artillery observatory. From there, on June 21, 1940, he directed the mortar fire that struck Chaberton. It is so well hidden as to be practically invisible."

"Wonderful viewpoint over the Clarée, the Guisane, Briançon. Allow 3h30 on foot from Montgenèvre (without the chairlifts), no particular difficulties but it is worth it, in the end it is magnificent. A must do."
