Vettabbia Park, Nature park in southern Milan, Italy.

Vettabbia Park is a large public green area in southern Milan, in Municipio 5, bordering the municipality of Opera and forming part of the Parco agricolo Sud Milano. It is crossed by the Naviglio Vettabbia, a canal, not a river, and its tree-lined avenues are home to ash, pedunculate oak, field elm, black alder and white and grey willow, with hawks, foxes, birds and owls often seen.

From the 12th century the monks of the Abbey of Chiaravalle reclaimed and farmed this land, and the opening stretch is still called Valle dei Monaci. The route ran on to the Po at Corte Sant'Andrea, linking Milan with the Via Francigena. At the park entrance, on a side lane off via Ripamonti, the old Mulino Vettabbia survives, converted to housing.

The park's name comes from the Naviglio Vettabbia, the canal that crosses it, and its first stretch is called Valle dei Monaci after the Cistercian monks of Chiaravalle Abbey, who reclaimed and farmed the land from the 12th century. The route through the park continues to the Po at Corte Sant'Andrea and links Milan with the Via Francigena.

The park has multiple entry points that make access straightforward, and works well for both walking and cycling. Keep in mind that trails through wetland areas can be slippery, especially after rain.

The waterway crossing the park is the Naviglio Vettabbia, a canal and not a river; it gives its name to the park and to the old Mulino Vettabbia at the start of the park, on a side road off via Ripamonti, now converted into housing.
