During your stay in Milan be sure to visit the Navigli which are a system of interconnected canals in and around Milan. Dating back as far as the Middle Ages, the system consists of five canals: Naviglio Grande, Naviglio Pavese, Naviglio Martesana, Naviglio di Paderno, Naviglio di Bereguardo. The best time to visit is in the evening as there are lots of bars and restaurants to visit in the area. This is an up and coming area but not currently a tourist hotspot.
