Enduro route in the upper Blenio Valley, around the tops of Pizzo Rossetto and Sosto, with start and finish in Olivone. It starts in Olivone towards the village of Sommascona, where a beautiful dirt road begins, which bend after bend, leads to the Saléi Alp. Here, with your bike on your back, you go up the path for about ten minutes to Simöu. A short break is a necessity, for you to enjoy the wonderful panorama. A short stretch on paved road leads to Anvéuda, where a challenging climb, with the bike on your shoulder, leads you in about twenty minutes to Cantonill, the pass that divides the Lucomango valley from the Campo valley. Here begins the challenging descent towards Campo Blenio, along the Scandorair path: steep, exposed, yet cycleable paths will put a strain on the technical skills of the biker. Once in Campo Blenio, continue towards Ghirone and go up the paved road to the Luzzone dam. Cross the dam and continue towards Compietto, at the foot of Sosto imposing peak. A partially cycleable "single trail", in the first stretch, takes you to Garnaira, where the second challenging descent begins, back down to Olivone.
