The ascent to Prato Valentino is the same paved road as track n 33, starting from Tresenda rather than San Giacomo. you can avoid some traffic congested road taking alternative roads that go up from Castelvetro to Vangione and then from Frigeri to the road that leads to San Rocco. Going right afterwards you meet the ascent from Teglio to Prato. This paved road, especially in the last part, is very hard. From Prato Valentino starts the descent. This can also be an option for whom, doing trail n 10 from Col D'Anzana, wants to descend downstream quickly. The descent is really easy, on a reasonably steep gravel road to Teglio. Afterwards the trail features gravel road sections, (few) paved road sections and cemented ones among the vineyards above Tresenda. From Prato to Teglio you can follow the signs reporting n 391- Piazza S. eufemia. Approximately 1,5 km after you have started the descent in order to avoid a rather hard section of the single trail- you'd better not turn left (crossroad S.Sole- brigna), but carry on till the mountain huts bollone, take for a short section the ascending trail and after the first hairpin go back on the gravel road on the left. Once in Teglio descend to Sommasassa passing Palazzo besta, run along the namesake lake, pass the San Gottardo little church and start the beautiful descent among the vineyards that takes back to Tresenda.
