The route starts in Olivone at 890 m asl and continues towards Campo Blenio along the old gravel road of the Sosto, which is included in the inventory of Swiss communication routes for its historic and geomorphological features.

Upon reaching Campo Blenio, you take the comfortable asphalt road that climbs into the Campo valley. After the hamlet of Orsàira, you enter a prized grazed larch forest, subject to a recent enhancement intervention by the local Patriziato. The presence of several old and monumental larches, of imposing size, is significant from a landscape but also ecological and biodiversity standpoint.

Almost at the edge of the forest, you reach the Alpe Predasca at 1742 m asl, loaded in summer by about one hundred cows, and proceed on a gravel road until reaching the Capanna Bovarina where you enjoy a fantastic view over the Luzzone area and the mountain chain overlooking the Greina plateau, on the northeast border of the canton Ticino with the Grisons.

The fun now begins with a medium difficulty singletrail descent. From the hut, along pastures and woods, a route specially created for mountain bikes unfolds which will reward the enthusiast for the efforts of the climb with an exciting and flowing downhill ride all in one go down to Orsaira. You return on asphalt to Pianchera where a comfortable trail brings you back to Campo Blenio and then towards Olivone retracing the old Sosto road.
