Magnificent 360° view of the North Belledonne massifs, the Grésivaudan valley overlooked by the long cliff of Chartreuse, the Bauges and the foot of Bugey behind the lake of the same name...

Perched at an altitude of 1,830 meters, the Aulp du Seuil passage offers sensational views. Crossing it offers a unique experience that does not include any difficulty.

A magnificent view of the valley, Mont Blanc... caves, cavities, carved by the elements in the rock of the cliff is exceptional. Be careful however because access can be complicated from the bottom of the valley and the place is private in theory (even if there must be a right of way).
