In this magnificent marshy area of national importance, we find almost all the wetlands we encounter in our country.
You can admire in particular a low marsh, reed marshes, a wet meadow as well as the biggest flooded alder forest of Switzerland. You will also discover the Veyron which can flood the whole area, the lakes of La Muraz, which were exploited for their clay by the tile mills as well as exceptional fauna linked to these environments. For example, you can observe many species of birds.
