The best walks and hikes in Parco Dell’Alto Martesana

Confine prov. Milano and Bergamo

The section of the Naviglio Martesana cycle path between Bellinzago Lombardo and Inzago is a flat, entirely asphalted stretch without technical difficulties, ideal for cycle tourists of all levels. This specific rural fragment runs for about 3-4 kilometers along the Martesana canal in a protected area.

The Locks of Bellinzago Lombardo are an important historical hydraulic engineering work located along the course of the Naviglio della Martesana. They represent one of the best-known stopping and points of interest for cyclists and hikers who frequent the canal bank. These historical hydraulic systems (locks or sluices) originally served to regulate the flow of water and allow commercial navigation between the Adda and Milan.

Naviglio della Martesana is perhaps the least known of the ancient artificial canals connecting Milan to the great Lombard rivers. It originates from the Adda in Concesa, a hamlet of Trezzo d’Adda, crosses the Martesana sub-region, northeast of the provincial capital, and once in the city, it plunges underground beneath Via Melchiorre Gioia, at the height of Cassina de’ Pomm. It measures approximately 38 km in length, with a width varying from 9 to 18 meters. However, once upon a time, the Naviglio della Martesana continued in the open air all the way to the center, where a lock system centered on the Conca dell’Incoronata connected it to the short Naviglio di S. Marco and the urban network of the Navigli. The lock was inaugurated in 1496, utilizing lock gates designed by Leonardo da Vinci. The canal had been opened in 1471, under Francesco Sforza. By connecting it to the other Navigli, Leonardo laid the foundations for realizing a dream of the Sforzas: to travel by water from the Ticino, and therefore from Lake Maggiore, all the way to the Adda.

The Naviglio della Martesana, initially known as Naviglio Piccolo, is one of the Milanese canals that connects Milan with the course of the Adda river through the municipalities of Martesana. Commissioned in the 15th century by Francesco Sforza, it was used for irrigating the countryside but also represented the ambitious project of connecting Milan with Lake Como and thus with the Alps and Ticino. The Naviglio della Martesana is a place rich in history and beauty, a heritage for everyone that, however, today is still little known and protected. Along the Naviglio runs a rather busy cycle path, which allows you to admire the landscape and cultural beauties, such as the rich flora, fauna, or the numerous historic villas, including the Renaissance Villa Melzi d’Eril in Vaprio d’Adda.

Leonardo's locks on the Naviglio della Martesana, particularly the Conca dell'Incoronata and the Conca di San Marco in Milan, are 15th-16th century engineering systems designed to overcome water level differences and connect the Martesana to the inner network of canals. Designed by Leonardo da Vinci, these locks used wooden leaf gates, designed to facilitate the passage of barges loaded with goods.

Beautiful walkway; you can push your bike and enjoy a truly breathtaking view of the Adda River. It's very busy on Sundays.

In Groppello d'Adda, along the Martesana Canal, there is a large waterwheel called "el rudun." It is not a mill, but a noria that was used to raise water for irrigation. It was built in 1618 at the behest of Cardinal Federico Borromeo. It was used to irrigate the vegetable gardens and gardens of the Archbishop's Villa. Tradition attributes the design to Leonardo da Vinci. The water also fed kitchens, washhouses, and livestock watering troughs. The original wheel was dismantled in the late 19th century. The current one is a 1989 reconstruction, restored several times. It has a diameter of 11 meters and eight large blades. Today, it is a historical and educational symbol that tells the story of the area's past.
