Description of the walk

Park in the car park at the church in Perriers-sur-Andelle.

(S/E) With your back to the church, turn left onto Rue de l’Église. Cross a wooden bridge over the Andelle and continue along Rue de La Forêt until you reach the junction with Rue de la Hétraie.

(1) Turn right onto this street, continue, passing a sports ground on your right and then a factory.
Pass a bus shelter on your left just before the junction.

(2) At the fork, head left then turn right onto thefirst track between plots 688 and 689; this is the Route Forestière (RF) des Châteaux. Follow the track until you reach another RF, the Colmont route.

(3) Follow it to the right; it also forms part of theGRP® desForêts de Haute-Normandie, marked in red and yellow. Continue to the junction at the De Colmont forest house.

(4) Turn left, leaving theGRP® which continues straight ahead. Follow this small road, which becomes a path after the farm on the right-hand side. Enter the forest, then at thefirst crossroads, head right to a picnic table and a brick building situated at the corner of a road.

(5) Take the path to the left at the signpost: Sentier de La Fontaine Bulant, marked in yellow. Leave this road atthe first path on the right. Follow it uphill for a few metres, then turn right again.
Continue along the path, then at the crossroads, head right onto the yellow-marked path that descends.

(6) At the bottom of the descent, stop following the yellow markings and turn left onto the Route Forestière du Chêne Varin. Continue until you approach some buildings.

(7) Turn onto the path that veers left between plots 748 and 749, then join a road. Follow it to the left until you reach the forest at the Maison Forestière de la Villenaise.

(8) Head right at the sign for Route Forestière de la Pierre Fortelle and take this road. Pass through a gate and follow this forest track until you reach plot 711 on the left.

(9) Turn left onto the small winding path and continue until you reach a wider forest track. Cross it to the opposite side.

(10) Follow the forest track to the left, go uphill and cross the road to continue along the track opposite. Continue to the junction of several paths at the end of a bend.

(11) Head straight ahead (do not head towards plots 702/704) then follow the path on the right. Walk to the bottom of a descent.

(12) Turn left, continue for about thirty metres and then turn left onto the Route Forestière Beaunay, which follows theGRP®. Follow this for a few hundred metres. You will come to a crossroads of paths.

(13) Turn right at a 90° angle and follow theGRP® to the edge of the woodland, which you should follow to the right. Join the Route Forestière de Colmont at the junction you passed earlier.

(3) Ignore theGRP® which heads off to the left. Turn right onto the De Colmont forest track. Reach afirst road, cross it and continue along the path opposite. Reach asecond road. Cross this as well.

(14) Go through the forest gate and continue to the crossroads.

(15) Follow the path on the left downhill. Wide at the start, it narrows further on and leads to a clearing. Then turn left onto a dirt track until you reach a road. Take it to the right to reach Rue De La Forêt.

(1) Go straight on, cross the Andelle via the wooden bridge, then turn into thefirst street on the right, keeping the church on your left. Pass between the two pillars on the left after the church to enter the grounds of the Manoir De Colmont. Proceed to the church and the starting car park (S/E)

A lovely walk, mostly through the woods.
A variety of plantations. Suitable for all seasons, but particularly pleasant in warm weather.
You can shorten the walk by a few kilometres by parking on Rue de la Hêtraie near point 2.
You can then visit Perrier/Andelle from the church car park... or not.
In any case, follow the description and/or the GPS track on your smartphone, as there are virtually no signposts on site.
Highly recommended

Hello, It would be advisable to note in point 5) that the first path on the right is also signposted as the ‘Sentier de la Fontaine Bulant’, as there could be some confusion with paths created by forestry work.
