The climb to the Sanctuary of Oropa from Biella is a Piedmont classic. It is about 13 km intense and constant, which do not allow respite with always challenging slopes. The iconic and hardest stretch is the last kilometer on the scenic pavé, made legendary by Pantani's feat in the Giro '99.

Of this mountain, after well over a hundred climbs, I know all the sides, it's a shame that some of the slopes inside the Val Sessera, e.g. the one for Rattarun and then Alpe Boscoso then climbing to Navagli and Alpe Campo and Cima ... are, for some stretches in the lower valley, a bit swallowed up by vegetation. The normal route from Ciota to the refuge is very popular, but for example the descent via Spelonca-Cascinetta still offers a nice ring that is more "wild" and very little frequented.
