(S/E) Set off from the chapel and take, on the other side of the D154 road, the street known as Chemin du Fourchet d’Orival, a tarmac road that climbs towards the forest (north-east), with houses on the right. Tarmac road uphill then flat dirt track.
Follow the Chemin du Fourchet d'Orival to the Orival fork.
(1) At the Orival fork, there is a signpost. Leave the Route Forestière de la Loge on your right – this will be your return route – and turn left and downhill onto the Route Forestière du Fourchet d'Orival (north-east).
(2) Caution! The Route forestière du Fourchet d'Orival crosses the Route forestière du Grand Maître. At this point, the track changes character and becomes less passable. To stay on the Route forestière du Fourchet d'Orival, you need to make a sort of double bend, right then left (north-east). Tip: you must head into the high forest between plot no. 151 on the left and plot no. 177 on the right. Do not take the Route forestière du Grand Maître, which is very passable. You will arrive at the Route des Limousins, a tarmac road.
(3) Turn right (south-east) along the pond. Take a moment to look at the Saint-Paterne pond. Follow the Route des Limousins to the Châtelet crossroads with five lovely roads.
(4) The Route des Limousins continues straight ahead through the forest. At this crossroads, it changes from tarmac to a dirt track. Take the forest road on the right at a right angle, the Route du Châtelet (south-west). Do not take the Route du Grand Maître.
(5) At the start of the Route Forestière de la Loge, about 900m from the Châtelet crossroads, leave the Route Forestière du Châtelet by turning right to head down towards the Orival fork via the Route Forestière de la Loge (West).
(1) At the Orival fork, the end of the circular path. Continue straight ahead, slightly to the left, to head back towards the Orival chapel via the same path as on the way out, the Chemin du Fourchet d’Orival.
At the end of the path, leave the forest, come out onto the small tarmac road, then onto the D154 and finally back to the starting chapel (S/E).
