This 67.6 km loop rolls out of Comacchio and back again, all of it paved. You head first into the Valli di Comacchio nature reserve, then pass the lake of Valle di Fattibello. On you go through the Parco regionale Delta del Po Emilia-Romagna nature reserve, with the Lago delle Nazioni lake rounding things off before the ride brings you home to Comacchio.
