Excursions without a car: You don't need a car to escape from the business, the traffic, the congestion, the fog in wintertime, and the afa humid heat in summer, of the city of Milan to a wonderful world of lakes, mountains, castles and good food: just take the train and, sometimes, the boat.

Biking Trips: Beginning at the 24th May Square Piazza 24 Maggio there is a excellent and very long bike road on the right northern bank of the canal. Be aware to take the Naviglio Grande going west on the northern bank of the canal and follow it as long as you want. After few kilometers you'll reach the nice Chiesetta di San Cristoforo, a popular spot for marriages. If you are well trained, proceed through the countryside. About 10 km to Gaggiano, a very nice and tiny village, and 20 km to Abbiategrasso. If you are still in the mood for riding, follow the canal on the right and reach Robecco sul Naviglio.
