Your route starts at the tourist office, but this building was formerly known as the Engineers' House and the Guard's House, as it housed the project managers and then the person responsible for monitoring the slightest movement of the dam. Take a look at the dam: 271 m long and 20 m high. It was built to regulate the flow of the Cure, a tributary of the Yonne and a tributary of the Seine, to control flooding in Paris and enable the Morvan wood that heated the capital's homes for nearly 300 years to be floated.
Arriving near Gouloux, you will have the choice of continuing on your way or making a diversion to visit the Saboterie Marchand and the legendary waterfall of the Morvan: the Saut de Gouloux. In the second part of your tour, you'll come across the hamlets of Nataloup, Palmaroux and Champgazon, which were once floating ports where timber was stacked before being thrown into the water. Your return journey takes you through the Cure valley, an area classified Natura 2000 for its marshy and paratourbous meadows.
