Circuit de Gravel: 300km loop from Nevers

Conquering the Morvan from Nevers station.
You don't need a car for this 300km tour, which takes you through the Nièvre from the south, then up the Morvan from its peaks to Lormes. Then, once again, you'll cross the central Nivernais via the plains of the Yonne valley and the Amognes.
