Very scenic aerial route rich in historical identities. Route with ground not always well-trodden, also due to disconnections caused by motorcycles and cars.

The Forte del Gran Serin or Batteria del Gran Serin is a fortification built towards the end of the 19th century to defend the northwestern borders, located along the Assietta road near the Colle dell'Assietta. The battery develops in length straddling over 2,600 meters in altitude, offering artillery positions, barracks including stables for a total that could reach 850 soldiers and a powder magazine, all protected by a long wall. The position covered with its fire from the top of the Assietta to the Gran Costa mountain, covering the Galambra valley, the Niblè, the Quattro Denti peak and the lower Val Cenischia. To date, the structure is in ruins and part of the wall is missing.

Beautiful military road kept very well. Once you reach the top, you turn at an average altitude of about 2300 m

This hill is best appreciated when climbing from Monfol because it offers an excellent panoramic viewpoint over the Chisone valley. You arrive at the end of a long traverse, very restful especially if cycled due to the moderate gradients. The downside is the significant traffic of off-road vehicles, almost all foreign, that use the beautiful high-altitude road known as the Strada dell'Assietta. Make sure to refuel along the way BEFORE the pass, taking advantage of the many streams, because from the pass onwards, whether heading towards Sestriere or towards the Assietta, you'll find almost no water... and there's a lot of dust! Another recommendation: avoid this route if a thunderstorm threatens, as there are no shelters and you risk serious lightning strikes!
