From this point three paths branch off towards different destinations. The path that leads to Mount Pancherot, directly to the south, is the shortest but also the most technical. Running up to Lake Cignana is pleasant and easy. Alternatively, you can take routes that lead to more distant destinations.

Ascent of the Banzai Trail — Cogne
Highlight (Segment) • Trail
At the end the whole thing flows into an approx. 2km narrow mountain path to the pass, here another approx. 300hm have to be overcome, which in my opinion can be exhausting, sometimes very steep places, especially at the end, bike carrying and good surefootedness are an advantage.
But if you still have enough juice in your legs after cranking 1200hm, you will manage that too.
Everyone else better go to the bike park in Pila! ;)

https://youtu.be/KdsaBL0twzY?si=-LI75WFE57aHMvCE Very well described by meckomat: first gravel, then 2km of singletrack, sometimes flat, sometimes steeper, the last 300m of elevation gain can only be achieved by pushing at least.

https://youtu.be/KdsaBL0twzY?si=-LI75WFE57aHMvCE It's not very difficult to reach, but you'll have to push the last few meters. The descent is easy. The landscape doesn't feel high alpine, but since it's all green, rolling hills, it's like being in Scotland or Ireland.

From the Italian side, you mostly have to carry the bike or use rails. Short sections are rideable. The descent into Val Ferret is mostly good, somewhere between S1 and S2. In some places, I had to carry/push the bike because it was too heavy. It took me about 25-30 minutes from the pass to Plan de la Chaux.
