A ring in the middle and lower Blenio Valley, with departure and arrival in Acquarossa. The route is pleasant and very easy, ideal for families who wish to ride on the valley floor away from main roads. A fun tour to discover suggestive corners of the territory along secondary paved roads, dirt road stretches and even easy single trails. You go down to Loderio through Dongio, Motto, Ludiano and Semione; you return along the left bank of the Brenno river, through Malvaglia, and again Motto, Dongio, up to Acquarossa. Monuments along the way: the Romanesque churches of San Remigio in Corzoneso Piano and San Pietro in Motto-Ludiano, the Serravalle castle in Semione and the oratory of the nativity in Loderio.
