Parking and start: coming from Les Essarts, just after the police academy, second car park on the left. Coming from Oissel, park 400 m to the right before the police academy, on Route Forestière du Fond du Catelier.
(S/E) Take the Route Forestière du Fond du Catelier to the second turn-off on the right.
(1) Turn right, continue for about 350 m and turn left. At the T-junction ahead, turn left and head down this path to the dip at the crossroads. Continue straight ahead (or, for those who find it a bit more challenging, first turn left then right: the slope is slightly less steep). Carry on straight ahead, ignore the first crossroads and at the second crossroads, turn left towards a roundabout.
(2) Turn right onto Route du Fond du Catelier towards Champs de Saint-Étienne. Pass under the power lines, ignore the first junction and continue to the Carrefour de Oissel. Turn left and carry on to the Carrefour du Chapeau à Trois Cornes.
(3) Turn left and immediately left again, onto Route du Fond de l'Essart towards Madrillet. Continue for approximately 430 m (until 50 m before the fence on the left), then veer right – be careful, the path is narrow. Keep going straight on until you reach the tarmac, Route de Belbeuf.
(4) Turn left, following the power lines; at the T-junction, turn left. Turn right onto the first path and immediately left; at the T-junction, continue straight ahead until you reach the road, Route du Fond de l'Essart au Madrillet.
(5) Cross the road and continue along the track opposite; ignore the turn-offs to the left and carry on until you reach the fence of the police academy. Follow the fence as it turns right, then for approximately 1,490 m. Then leave the fence, which turns right, and follow the track until you reach the circular bend in the road, Route du Fond du Catelier aux Champs de Saint-Étienne.
(6) Turn right and follow this road to the car park (S/E).
