Start: Ermitage à Franchard car park.
Access: The car park is located a few metres away from a crossing with a cross on the D301, called "Route Ronde" (signpost). The crossing itself is close to a crossing between "Route Ronde" and the D409, linking Arbonne-la-Forêt and Fontainebleau (when arriving from this crossing, turn right).
No Waymarks
(S) At the other end of the car park (west), take the lane towards "l'Ermitage" (sign). Go past the "Promenade de Franchard" signpost. You'll get to a "Arbor&sens" signpost: leave the lane finding "la Fontaine de l'Ermite" (fenced up).
Blue Waymarks + Blue markers using letters
(1) Take "Sud le Sentier Denecourt-Colinet n°7" to the south: head on a path that weaves between the rocks, leaving the fountain to the right-hand side and the signpost to the left-hand side. After winding through the pine forest, you'll reach a blossoming rock bearing a Blue star ("Le Sphinx des Druides", see photo). The waymarked trail soon divides into two branches, take the one leading to "Franchard par l'Antre des Druides" (signpost): when in front of the stared side of the rock, steer right (east, waymark a little further on a tree).
Near a small rock to the right that looks like a helmet, turn left. Reach the top of a mass of rocks giving a view point towards the north. Go back to the left (south). After what looks like a large step, head right going past a rock shelter marked with an L then past the rock marked K. Cross a rock maze, pass under a rock then through a narrow passageway. Head along the left-hand side rock shelters G, F and E. Go through another narrow passage, leaving rock D to the right-hand side and once out, locate the D marking on the left-hand side. Cross a maze and another narrow passage, C. Once out, continue opposite then turn right. Head down a few minor bends reaching a path (Route Raymond, forest plot n°762).
(2) Follow the path on the left (south). At the next crossing, turn right onto a large path (Route des Gorges de Franchard, Red and White waymarks). After around 50 metres, leave the path, heading right up towards a mound. At the top (rock marked with a Blue star), go left (west) across a flat landscape. A bit further, head left again leaving rock V to the right-hand side. After a flat area, perform a dogleg right, then a dogleg left onto a narrow passageway. Once you get to exit U, turn right. Go past shelter T reaching " l'Antre des Druides", a vast rock shelter (on the left).
Keep heading west climbing a few sandstone steps then head down slightly. After a flat area you'll reach viewpoint P. Keep heading west (don't try to go through the "holes" on the right), then turn left (south) downhill reaching Route des Gorges de Franchard. There, turn right onto a large path. At a crossing after roughly 150 m, turn off to the right (north-west) onto Route du Carnage which heads off behind a tree bearing a sign (ignore the footpath - which isn't on the map - at the foot of the tree heading off at a right-angle to the right). The path is windy and loses in altitude.
No Waymarks
(3) At the crossing, turn left onto Route Amédée, leaving the Blue waymarked path head uphill, opposite. Move through the gorges, within a pine forest filled with beautiful fern undergrowth ignoring faint trailheads to either side. At a fork, steer right onto Route des Buttes de Fontainebleau leading to the GR11 (sign). Head down slightly, due north, ignoring trailheads on both sides, reaching Route du Renardeau (old forest car park, now sealed off).
Red and White Waymarks
(4) Take a right-angle turn onto Route du Renardeau on the right and follow the GR11. At Renardeau crossing, turn right onto Route de l'Ermitage (ignore the 1st footpath heading up).
No Waymarks
At the next crossing, take the first path to the left, Route du Carnage, which starts with a climb up a wooden staircase. At the top of the staircase, climb another few metres then take a sharp turn right (don't follow the path heading north uphill). You'll come across another wooden staircase and reach a pass (signpost "Promenade de Franchard").
Yellow "Hikers" Plaques
(5) Turn right towards the viewpoint. Zigzag between the trees and the rocks keeping to a western direction. Next, turn right (north) reaching the top of a large rock "terrace" giving you a huge panoramic view to the north. Then backtrack (the plaques are there for both directions).
Blue Waymarks + Yellow "Hikers" Plaques
"Here, the Yellow waymarks are on one side only, arrows pointing in the opposite direction".
(5) Back at the pass, cross Route du Carnage, regaining Denecourt-Colinet n°7 trail and head due east through a pine forest. Go past a viewpoint over the south and remain at the edge of the mound (right-hand side).
From here, it's no longer possible to give a precise description: the route is tortuous and faint footpaths sway within direct passages on the rock. Basically, keeping to an eastern direction, shift between passages on the southern edge of the mound and left-right hooks which take you further from the edge. Follow the waymarks and keep to an overall flat landscape.
After about a kilometre, you'll start to see Franchard observation tower above the forest. You'll quickly come across a sandy crossing ("La Roche qui Pleure" information signpost).
(6) Turn right in order to get a glimpse of the nearby rock shelters. Backtrack.
(6) Keep heading east along some sandstone steps. Cross a flat area, then a lawn with trees leading to "l'ermitage" already in sight. Turn right leaving l'ermitage to the left-hand side and reach Fontaine de l'Ermite.
No Waymarks
(1) Keep heading east, follow the lane from the beginning and regain the car park (S/F).
