Pass mountain hut Camplano and amongst the meadows and blooms of edelweiss push your bike up to the summit of Mount Grem where you can enjoy a beautiful view of the Orobian Prealps. Once back on the path remount and keeping left ride on the 263 along a short grassy ridge towards mountain hut Mistri. Keeping to the opposite ridge towards the Terza Baita di Grem descend along a track towards two houses. Following the CAI 223 you reach Sinele, take the track back to Passo di Zambla.
