From Valnontey hamlet follow a dirt track that, climbing up the Valley, leads to the Valmianaz village, perhaps the best example in Cogne Valley of local architecture, both as individual buildings, and as components of a conglomeration. Along the way is definitely worth stopping by the well known Prà Suppiaz peat-bog, very delicate damp environment, so we suggest to approach with caution to be able to observe the typical aquatic vegetation and fauna (grass snake, common frog, etc). Passed Valmianaz, go along an easy trail and, paying attention especially to tracks of ungulates, we arrive at the foot of the magnificent glacial Amphitheatre of Valnontey, and then later at the Pont de l'Erfaulet.
Path accessible with dogs from Valnontey to Pont de l'Erfaulet, from the 15th of July to the 31st of August.
