From the Mottolino headquarters, follow the bike path to the Vago area, then begin the ascent of Passo Forcola. After passing the customs post, continue along the road for a few hundred meters, take the trail on your left to the La Rösa area, and then proceed towards Sfazù. Once you reach the Saoseo refuge, continue straight (the sign indicating Val Viola to the right is for the pedestrian path) and reach the Viola refuge, where you can enjoy delicious food and recharge your e-bike.

From the Viola refuge, continue until you intersect the SS301 at the Arnoga hairpin turn: Here, you need to ride on the road for a few dozen meters, then turn left at the Arnoga church and take trail 195 towards the Torri di Fraele, which will lead you to the Cancano Lakes.
To return to Mottolino, ride back through Val Alpisella and return to the headquarters: your legs burn, your arms too, but you've completed the most EXTREME tour among those offered!
