At the fortress called Rocca della Stellata you can take a cycle route that is about 125 km long and runs along the River Po up to the delta. Its is called Ciclovia Destra Po and is one of the best known cycle routes, the longest in Italy, marked by signposts and entirely reserved for cyclists. Take your family on this beautiful cycling tour in the spring or in autumn. You should plan at least four stops before reaching the Po Delta, even though there are so many examples of the local historic and artistic heritage along the way that you could consider to add a few more.
On the other bank of the river, on the left embankment, there is a parallel cycle route, consisting mainly of paved roads, only partially reserved for cyclists but all with limited car traffic. It is called Itinerario Sinistra Po and you can take it either from Melara or even from Mantua and cycle up to Porto Tolle. 150 km of river landscape to be explored cycling slowly among natural oases on the river bank and museums dedicated to the river and to past land reclamation.
If you only have one day you should stop in Ferrara and take a bike at the Estense Castle. From there you can follow the itinerary of the city walls (Mura di Ferrara) mostly paved and protected, wich is about 9 km long and is perfect for families with children. If you are looking for something more ambitious you can choose one of the many itineraries on cycle routes starting from the city and following the waterways. There is one running along the canal canale Burana that crosses the Ciclovia Destra Po; and another one that follows an old branch of the river called Po di Primaro, all the way to the delta.
You will find out that the River Po is not the only waterway in this area and that you can cycle in the Veneto region on the cycle route running along the Tartaro – Canalbianco, from Melara to the Po di Levante, through a rural landscape dotted with Renaissance villas and the land reclamation plants built in the 20th century.
