Parco dell'Oglio Sud, Regional park at the Oglio and Po rivers confluence, Province of Cremona and Mantua, Italy

Parco dell'Oglio Sud is a regional park of 12,800 hectares established by Lombardy Region, stretching along the Oglio from the mouth of the Mella, between the provinces of Cremona and Mantua, to where the river joins the Po near Torre d'Oglio. Its single-channel river has evident meanders and steep banks, with broad sand beaches emerging at their foot in summer; oxbow areas stand out as poplar woods and white willow borders, and a dense water network cuts the farmland.

The park was established in 1988 as a conservation area protecting the river landscape between Oglio Nord Park and the Po confluence. This designation came from a growing recognition of the need to safeguard lowland river systems in the region.

The park's name comes from the Oglio, the river it follows from the Mella confluence to Torre d'Oglio, where it meets the Po. The protected stretch is the southern part of the river; the plain section from Lake Iseo is covered by Parco Oglio Nord. The managing body, Parco Oglio Sud, is a regional public-law authority with offices in Calvatone.

Visitor centers in Acquanegra sul Chiese and Canneto sull'Oglio offer maps and information about walking trails and wildlife viewing opportunities throughout the park. Early morning visits work best for spotting birds and other animals, and comfortable walking shoes are helpful for navigating the often wet or muddy paths.

The area includes several Natura 2000 protected reserves such as Le Bine and Torbiere di Marcaria, which support specialized wetland birds and rare plant species. These reserves provide refuge for species that struggle to survive in the industrialized agricultural landscape surrounding the park.
