Along the path that winds through the valley floor, countless testimonies of the valley's past are encountered. Starting from Olivone heading towards Biasca, after crossing mule tracks and trails, you reach the core of Ponto Aquilesco and the hamlet of Aquila, then reach the hamlet of Dangio passing in front of Cima Norma, an old chocolate factory that in the last century significantly contributed to the valley's economy, producing up to 1,500 tons of chocolate in the 1940s–1950s and employing over 300 workers.

A short climb on a trail leads to the pass where the castle of Curterio once stood, of which no significant traces remain, where in 1182 the Pact of Torre was signed in which the people of Blenio and Leventina declared their desire to remain free, with no jurisdiction other than that of the Milanese.

The route then continues towards Lottigna, home to the Blenio Museum, then descends along a trail to the Acquarossa Thermal Baths, a well-known place of cure throughout Switzerland. The current building, now closed since 1971, was inaugurated in 1886.

Continuing along the old Satro road, you arrive in the hamlet of Dongio passing through the grotto area and vineyards, where you can easily admire with the naked eye the Pagani house hanging on the rocks overlooking the village.

The path then continues between Motto and Malvaglia with a stretch of dirt road along the route of the Biasca-Acquarossa railway line, built in 1911 and dismantled in 1973. After crossing the hamlet of Malvaglia, the route heads towards its end, passing through Legiuna, a floodplain area of national importance.
