Once in Mazenay, park in the square near the church.
(S/E) From the car park, turn right onto rue de Brechau "D225". Follow the signs to the end of large bend to the left, almost at the top of Mont Rome Château.
(1) There you'll see a small marker on the right, "Fontaine des Dames": follow it to the summit. Cross the summit platform towards the pylon.
(2) Take the small signposted path that begins the descent, follow it to a crossroads marked "La Croix Bouchot".
(3) Turn left, follow it for about 500m and take a path on the right. This path veers quickly to the left, follow "table d'orientation" (orientation table).
(4) Turn left to Paris-l'Hôpital. There is a signpost for the crossing: follow it to the cemetery.
(5) Turn left immediately and follow the signs to the Marcheseuil exit.
(6) Turn left and follow the signs to Mont de Rème.
(7). The summit is poorly signposted, but a poorly marked path is visible, follow it to cross the plateau. Another poorly marked but signposted path starts the descent, take it, straight downhill.
(8) At a crossroads, turn left, then first right, crossing a tarmac road. Follow the path to another crossroads.
(9) Turn left "GR® sentier Jean-Marc Boivin". Follow the path in a straight line to a tarmac road, which you must cross to continue on the farm track for less than 100m.
(10) Then take the left-hand path which takes you straight into Mazenay, then left again to the starting point (S/E).
