In this magnificent marshy area of national importance, we find almost all the wetlands that we find in our country.
We can admire in particular a low marsh, a reed bed, a wet meadow as well as the largest flooded alder grove in Switzerland. You will also discover the Veyron which floods the entire area during high floods, the ponds of La Muraz, which were former clay pits exploited by the tile factories as well as an exceptional fauna linked to these environments. For example, you will be able to observe many species of birds.
