Wonderful high altitude path next to the highest edges of the valley bordering with the Vanoise french Park. The almost flat path runs along the glacial basin of the Serrù lake. It represents an incredible opportunity to observe the alpine environment in its entirety; ibex, chamois and typical Alpine fauna typical of high altitudes frequent the Lake, the prairie houses curious families of marmots, while eagle and bearded vulture often fly over with an eye to the nearby valleys, extraordinarily shaped by the erosive action of the numerous glaciers.

Upstream of the Pont-Valsavarenche village, left the car in the large parking lot of the Hotel Gran Paradiso, pass the bridge over Savara on the left and walk on a wide part of the plain in Seyraz Valley, up to the Tétras Lyre hut. The trail, well marked and very popular, then climbs in the larch forest until you reach a dominant rocky balcony, from which one can notice the whole Amphitheater of the abovementioned valley.

The itinerary starts from the Valnontey village, next to the Paradisia Alpine Garden, where almost all the natural environments of our mountains have been reproduced, so as a butterflies garden, which view is suggested, before walking through the itinerary. The trail winds for the first part into the forest to then continue in the high altitude meadows; the area is one of the most frequented by the animal symbol of the Park, the ibex, other than chamois and marmots.

From Ronco Canavese, main village of the Soana Valley, where the Visitors Centre dedicated to traditions and biodiversity in the valley is located, you can take the path to the Nivolastro village, one of the best examples of alpine architecture in the Soana Valley. Along the whole path it's easy to get suggestions on the social life of the past: you can observe the special votive chapels built for protection and resting of travellers as well as a distinctive abreuvoir just before the village.
