I'd been dreaming of being there for a long time, and I finally made it. It's a simply wonderful place. Words needn't be written. I climbed to the pass on its eastern slope, the one that starts from Pian dell'Alpe, and previously climbed Colle delle Finestre from Susa. Combining the two sections, I can assure you it's one of the toughest climbs I've ever done, but also one of the most beautiful. The section from Pian dell'Alpe to Colle della Assietta is divided into three parts: the first 4 kilometers of a steady climb at 6-7% gradient, the 2-kilometer intermediate rest stop, and the final 4 kilometers with steeper gradients and a worse track condition. I wholeheartedly invite you all to enjoy this wonderful place.

This hill can be reached from Colle delle Finestre via the old military road. The last stretch is on a trail to bypass the road closure due to construction (July 2025).

⚠️Be careful of the mandatory portage section to skip the collapsed point, the only passage if you want to continue and reach the Mezzodì and its unforgettable view 🤩
