(S/E) From the Rochers du Bas Cuvier car park, head north on the Route de la Solitude, which winds between the rocks (red and whiteGR® markings).
(1) When theGR®1turns right, continue left (oldGR® markings, small climb between two hillocks) towards the Point de vue du camp de Chailly.
(2) Before the end of the climb, turn left onto the Route du Solitaire (sign a few metres ahead) which descends towards the D607 (formerly the N7). There is a very large oak tree along the way.
At the next crossroads (D607 nearby), turn right onto Route Briquet. After this road turns right, you will reach a crossroads.
(3) Turn right onto the road that climbs back up to the plateau. Climb back up the plateau via a steep slope. At the top, turn right until you reach the viewpoint of the Chailly camp.
(4) Turn around and, at the first Y-junction, take the right-hand branch, then turn left (leaving the Route de la Solitude on your right). You are now on the Route du Boutoir (well signposted and a straight, clearly visible path). Immediately leave the Tournante de Cuvier Chatillon road on your right. You will then come out onto the Route de la Laie. Follow it to the left.
(5) When you reach Route des Ventes Chapelier, turn left. Go down the hill in stages, cross Route Briquet, and continue to Route de Barbizon à Samois et à Brolles (signposted).
(6) Turn right. You will cross the Route du Clocher.
At the second crossroads, before a slight right-hand bend, turn left and then immediately right (there is a marker in the middle of the crossroads) to follow the forest boundary (Route du Bornage de Chailly) (attractive markers) until you reach the road from Chailly to Samois.
(7) Then turn right and follow this road (which quickly becomes sandy) until you reach the Carrefour du Merle Blanc. At this crossroads, continue on the Route de Chailly à Samois, which is the second road on the right.
(8) After 1.4 km, you will reach a large crossroads. At this crossroads, turn left onto the Denecourt-Colinet path no. 12, taking the Route de la Femme (the sign is behind the oak tree on the left).
Follow this blue-marked trail: picturesque rocks, traces of an old orange circuit on the rocks that is hardly used anymore, a very old oak tree two-thirds of the way along this section... After a blue "E" mark, you will cross a path. After an overhanging rock (marked "F", rock on the ground), a steep descent leads to the Route des Monts de Faÿ (no sign at this point, boundary of plots 859 and 858, a beautiful Scots pine bears the blue trail marker "12").
(9) Turn left at the crossroads 50 metres ahead (route du Serpolet on the left andGR® signpost at the crossroads).
(10) At the crossroads, you will arrive on the Dammarie road, which you follow (north-west) to the edge of the Mare aux Evées. This section corresponds to an old TMF route that still appears on maps, but its markings (green and white) have been erased or scratched off. You can still make them out. Along the way, you will cross several roads, in the following order: Route du Lancer, Route des Bécassières, Route de Vitry, Route de Chailly à Brolles, after which the Dammarie road veers slightly to the left. Continue straight ahead (oil well) and after the next crossroads (continue straight ahead), turn right towards the Mare aux Evées, near the drainage ditches (allée des Frênes, marked 50m). This lane turns right off a beautiful beech tree.
From the pond, take the third exit, turning left (allée de peupliers de Virginie-écriteau) until you reach the road to Faÿ.
(11) Follow it to the right, then turn immediately left onto Route de la Table du Roi, then take Route Péraut on the right until you reach the Table du Roi crossroads, which you cross (be careful of traffic; there are traffic lights to help you cross).
(12) Take the Route de la Ruelle, which descends to the Seine.
(13) Turn right along the Seine.
Follow the river to the bridge (a small, quiet paved road, markedGR®). Go up to the road leading to the bridge and turn right to reach the Bois le Roi station, where you will find theGR®1/TMFon the other side of the tracks (underpass).
(14) Take this well-marked path, which quickly joins the forest via fairly quiet streets and becomes the Route de la Perlure in the forest. Cross the D138 and continue along the Route de la Perlure.
(15) When theGR® turns left, continue straight ahead and cross the road (D606, formerly N6). Opposite, take the Route du Lancer. Cross the Route de Solférino, then cross the Route des Vieux Rayons and follow it to the left. Pass the Carrefour des Vieux Rayons until you cross theGR®1again (Route de Chailly à Samois, paved at this point).
(16) At this crossroads, turn diagonally right (south) onto the Route du Limier (narrow at the beginning) until you reach the Grand Maître table (18th century), which you will reach after a fairly steep climb.
(17) Cross the road (be careful) and take the Route de la Table du Grand Maître opposite (according to a Visorandonneur, there are no longer any enclosed plots at this point, with passages in the fence). Follow it until you cross theGR®1again.
(18) Continue straight ahead (theGR®1turns left) and, at the end, take theGR®1opposite. Go down the old quarry face and, after a climb, follow theGR® on the left onto the plateau and then into the Cuvier-Châtillon rocks: this will take you (after numerous twists and turns and a few climbs and descents...) directly back to the Route de la Solitude and the car park.
