From the former parking lot of La Cuisinière, take the large path of La Route des Buttes de Fontainebleau between the classical area and Cuisinière Crête Sud, and follow La Route Amédée for 500m after the crossing with the GR. After a bend to the right, take a small path in the slope; its left branch leads to the start of the red circuit D+. Other problems, more difficult in general, have been opened along this circuit.
