The development of Saint-Maur is closely linked to the Marne. A story that dates back to the development of freight transport on the river with boats pulled by horses on the towpath. In the 19th and 20th centuries, leisure activities attracted a large population every Sunday with many guinguettes, some of which settled in islands. The latter are today spaces for the protection of biodiversity. During the cruise aboard a catalante, you can get close to it and discover a remarkable fauna and flora.
