At the heart of the Park, the forest massif alone covers 40% of the land surface. On this vast clay plateau with grindstones, dense forests and a few clearings testify of an intense human activity and the leading role played by the forest in the past. At 288 meters high, this is where the highest top of the Park and of the Marne area too culminates: the Mount Sinaï.
With countless legends and mysteries, the forest shelters a variety of species including a few rarities, to the delight of nature lovers. It is a popular destination for practising sports and leisure activities, while wandering, let this exceptional green oasis and its unexpected treasure win you over!
