The ‘Pian di Spagna’ plain, a wetland of international importance, was primarily formed by extensive flooding of lake Mezzola. The landscape is dominated by reed thickets. There are also hardwood forests, large expanses of grazing land and corn fields. The ‘Riserva Naturale Pian di Spagna e Lago di Mezzola’ (Pian di Spagna – lake Mezzola Nature Reserve) is the ideal place for nature walks, whether you want to relax surrounded by nature or observe the local wildlife.
