The first Po flood bed ring-shaped itinerary develops along the Bassa Lodigiana area, connecting the main centres and towns of the area: Codogno, Somaglia, Senna Lodigiana, San Rocco al Porto, S. Stefano L. and San Fiorano. The core of this itinerary is the environment, with impressive landscapes along the Po bank road and around the Monticchie natural reserve.
