Magnificent plateau accessible on foot from Engins, by bike from the mortar tunnel or from Les Égauds (mountain bike/gravel) or by car from Autrans. Shuttles make the bus trip to limit the number of cars.... Summer or winter, the panorama is just magnificent. Chartreuse, Belledonne and on a clear day you can see Mont Blanc perfectly.
