This is the 2nd time I've heard about this road. It is indeed supposed to be excellent. I'm close enough to have a look when the snow clears next year. Unless of course it's passable by 4WD now?In the West, a good alternative road, known largely to the locals, is to go from La Lécherette, past Lac de l'Hongrin, and through the mountain to Corbeyrier and ending at Yvorne near Aigle. I would highly recommend this road. The top part is a Swiss military training area and the road is in very good condition with wide sweeping bends. You then have fabulous views over Lake Geneva before the road becomes very narrow and winding as it decends through a series of tunnels to Yvorne. On some maps this road is marked as closed - it can be during the week if the army are playing - but on weekends it is usually open.
