Start out from the car park behind the cemetery in Noisy-sur-Ecole.
(S/E) With the cemetery on your right, turn left (north-northeast) along Chemin de la Plaine de Jean des Vignes.
(1) After about 200m, at the crossing, take the bridleway on the right. The bridleway runs more or less parallel to the Chemin de la Plaine de Jean des Vignes, which it joins again after about 2km, at the foot of Rocher de Jean des Vignes.
(2) Turn immediately right onto Chemin du Rocher des Potets. The path heads east and then bears southeast further along.
(3) Cross straight over the Ancien Chemin de Melun and continue southeast.
(4) At the next junction, join the GR1. Turn right (southwest) onto the Chemin du Rocher Fin, and follow the red and white waymarks of the GR1, ignoring any paths off to either side. Just after a bend to the left, ignore a path from the right and continue southwest.
(5) Turn right (southwest) along Chemin de la Mée. Ignore the paths off to the left and keep going until you reach the junction with the Sentier des 25 Bosses (it is much narrower, so be careful not to miss the crossing). Look out for a red two-directional arrow.
(6) Leave the GR and turn right down the path, which is waymarked in red. At a crossing turn left and climb up the east slope of Rocher Guichot. Come back down on the north slope. At the T-junction turn left and you will immediately reach the junction Carrefour des Longs Réages.
(7) At the junction, take the path to the right at a right angle (north-northwest), still following the red waymarks. The path makes a series of bends to the left-right-left, and then climbs up Roche aux Sabots
(8). Ignore the path with red waymarks, which bears off to the right (north), and begin the descent to the west. Cross Chemin de la Plaine de Jean des Vignes and make your way back to the starting point.
