The Valpiana Marshes are located in the homonymous district near Valmorel, in the Belluno Prealps. This wet and authentic environment formed about 20,000 years ago as a result of the retreat of the Piave glacier. The depressions left by the ice, characterized by low permeability, have favored the accumulation of water. Under these conditions, the slow decomposition of vegetation has generated peat.
The area, ideal for observing nature in complete silence, is divided into three zones: the woods and shrubs of Nantei, the low Central peatland, and the wet meadows of Nice.
The marshes are recognized as a SAC (Site of Community Importance) for their high floral value. The ecosystem hosts a remarkable variety of plants, including water clover and ten different species of wild orchids, such as the rare Orchis ustulata. The fauna is equally rich and includes insects, amphibians - among which are 3 species of newt - reptiles, mammals, and some threatened migratory bird species such as the Quail King. Among the larger mammals, deer and roe deer are particularly common to observe in the early hours of the morning or at dusk.
