Roll out of Ponte di Legno and the road soon points you through the Parco Regionale dell'Adamello, a nature reserve that sets the tone for the day. Next comes the Castello di Poia, a castle that marks the way before the route follows the Fiume Oglio and later the Adda, both rivers keeping you company on the pedals. With 3264 m of climbing across 91.3 km, it's a day that keeps giving, and the loop brings you back to where you started in Ponte di Legno.
