Monte Chersogno
Description
This giant tour starts in the small village of Prazzo inferiore in Valle Maira. From here, the route follows an old military road on asphalt via San Michele di Prazzo towards Grange Chiotti to the small chalets. It should be noted that it would be possible to take a shuttle to this point. This would make the tour much easier and save energy for the descent. From Grange Chiotti, a recently built, scenic feeder road winds its way up to the Colle di Chiosso Ouest saddle (2435 meters above sea level). From this saddle, the bike is only carried or pushed upwards and you are immersed in a spectacular mountain world that seems bizarre and lonely. Hikers or other bikers are rarely encountered on this route. The summit now comes into view, and you fight your way up to the Passo Chersogno (2880 meters above sea level). It should be noted that this section is the most challenging part of this tour. From the saddle, you have to bite through another 150 meters in altitude before you reach the magical 3000-meter mark directly at Monte Chersogno (3026 meters above sea level). 360-degree panorama guaranteed and pure alpine biking!
The upper section of the downhill is relatively easy and winds its way up to the saddle at S1 to S2 level. After that, the trail abruptly changes to S3 to S4 and remains similar for the next 200 Elevation loss. Back to Colle di Chiosso Ouest, the historic trail reaches S3 level in places, with the hairpin bends being in a class of their own. The route then climbs again briefly towards Colle San Michele (1950 meters above sea level). Up to Colle Passetti, the path is relatively overgrown and of S2 difficulty. Afterwards, the trail leads back to Castiglione at S2 level and a small uphill is waiting to be completed before you pass the viewpoint in the direction of Grange Albeno and then Vallone and descend the trail at difficulty levels S2 to S3 via Ussolo back to Valle Maira. The last few meters back to the starting point run along the valley floor and give you enough time to cool down.
Conclusion: All in all, probably one of the toughest tours in Valle Maira and also one of a special kind. It's all about pushing through and afterwards you feel like you've been knighted in the biker's life. It's essential to tackle it in stable weather, and you need to be in perfect physical condition and technically proficient.

A shorter version of the route, starting and ending in San Michele di Prazzo, was completed on September 24, 2026.
A fantastic tour to a beautiful peak—the locals call it the “Cervino della Valle Maira.”
Regarding the descent, it should be noted that the trail on the summit flank has been severely damaged by severe weather. Anyone who wants to ride down this section cleanly must be proficient at S4.
It should also be noted that just below Passo Chersogno, you’ll have to push your bike for about 30 to 40 meters of elevation gain, as the terrain is too steep and too rocky.
The traverse from Colle Passetti is simply brilliant. Awesome ride!
