Start at the car park of the Jacques Copeau Les Grandes Vignes Demigny multi-purpose hall.
Access the car park from the D19 by turning left towards Chalon-sur-Saône, then take the Montée des Poteaux opposite the old railway gatehouse on the disused railway line. There is an information board about the routes. Along part of the route, the ‘Discovery’ route (marked in purple) shares the path with the ‘Grande Boucle’ route (marked in yellow), the botanical route (marked in green) and the ‘7 Ponds’ route (marked in blue).
