Introduction

A pleasant hike starting from the village of Promiod and climbing up the wide valley of the same name. When you reach Col Portola, you can admire the splendid panorama of the Monte Rosa group.

Description

0h00' From the car park, proceed in a southerly direction as you enter the village of Promiod and, after a short descent, you will reach the chapel dedicated to Saint-Antoine (fountain 💧 on the right). Continue along the lane, now slightly uphill, until you come to the start of the path 💧 a little further on on the left.
Following the dirt road (there are several possibilities to cut the wide hairpin bends) you reach the Boettes (1714 m) and Sopien (1884 m) huts, to reach the wide basin at the end of the Promiod valley. Continuing along the path we reach the Revard huts (2031 m) and finally meet up with itinerary (departure from La Magdeleine).
Continuing the ascent with itinerary we reach the La Nouva alpine pastures (2193 m): the last dwellings we will encounter on our route. Leaving the dirt road, we cross the meadows on a path that leads to Col Portola (2410 m). We now continue along the ridge along the path, with an excellent panorama of the Ayas Valley and the Monte Rosa massif in the background. You finally reach the summit of Monte Zerbion after passing a somewhat uneven stretch of path.
