A river promenade along the Yonne river or its tributaries allows one to discover the rich Northern Burgundy ecosystem and its varied landscapes: huge forests on the riverbanks; the small town of Joigny nestled between the Yonne and the vineyards; the Othe forest with its moors, springs, ponds and other wetlands; the Southern borders of the Champagne plateau and its chalky soils; the valley of the river Vanne and its dry lawns on chalk classified Natura 2000.
