From Bormio, after 10 km of paved road, with a series of hairpin bends that make the slope not too steep, you arrive at Bormio 2000.
At that point, take a dirt road that leads to Rocca. After the ski lift of the same name, take a singletrack, which initially climbs gently and descends gently at the end.
The panorama is spectacular and Mount Tresero towers majestically above Santa Caterina.
In the locality of Sobrettina there is a dirt road that leads first to the huts of the Monti di Sobretta and then via Calvarana you return to the paved road that leads back to Bormio.
