The nature and vegetation are expressed in Nogent-sur-Seine in parks, open to the public today and in the incredible expanse of vegetable gardens (about 18 hectares) bordering the main roads of the city. Unfamiliar to Nogentais because masked by the linear urbanized, these gardens crisscrossed by multiple paths and roads constitute a vast space exploration for those who can identify. To discover the rich natural heritage and landscape and varied, go for a hike of 5.5 km (white markings and green). Map available at the Tourist Office.
