Coye Forest and Hérivaux Abbey in Luzarches

A very varied walk north-east of Luzarches: peaceful valleys, beautiful trees in the Forest of Coye and the remains of the former Abbey of Hérivaux, where B. Constant lived (after largely destroying it...)
The walk mainly follows marked paths (PR® at the start, thenGR®1andGR® 655).
Very peaceful despite the proximity of Paris.

Description of the walk

Car park at Luzarches church.

(S/E) From the car park, head east and cross the D316 (2 roundabouts).

(1) At the second roundabout, follow theGR®1on the left, along the departmental road. You will soon come to a fork and take the right. TheGR® descends gently into the Ysieux valley (beautiful views of the church of Luzarches when you turn around). It joins a small road which you follow to the left. Shortly afterwards, cross the stream at the Pont de Brassay.

(2) At a right-hand bend, take the path on the left. It runs alongside a wet meadow and quickly reaches a fork. Take the right-hand path (stillGR®1) and climb up through the meadow and into the forest.

(3) At a fork, take the left-hand path (PR® Jaune). The straight line on the map does not correspond to the actual terrain: thePR® actually follows the dotted path along the edge of the hillside on the left.

(4) You will come to another junction: take the fairly steep climb on the left (yellowPR® ).

(5) At the top of the climb, take the Route des Brûlis on the right until you reach the Carrefour de Chaumontel at the bottom of a descent.

(6) Follow thePR® on the right (east): this is the Route de la Verrerie. It climbs and descends several times between small peaks (such as the Pain de Sucre) crowned with a few sandstone rocks. Ignore the paths on the right and left and arrive at the Carrefour de la Verrerie, at the bottom of a descent.

(7) Turn right onto the Route Pavée de la Ménagerie, which is a wide path, and arrive at the Carrefour de la Ménagerie, where you will find theGR®1markers.

(8) Turn left and the path climbs up onto the plateau. Continue straight ahead for about 1.2 km until you come to a wide path at the Carrefour de Luzarches.

(9) Take theGR® on the right. It leads to the edge of the forest.

(10) At the crossroads, turn right onto the path (which quickly becomes a small tarmac road) that descends into the Hérivaux valley and continue past the entrance to the castle. Opposite, behind the building along the road, you will see the roof of a tithe barn. Nothing is open to visitors. The ruins of the abbey can be seen beyond the gate of the property.
Continue along the road that turns west.

(11) At the crossroads, take the road on the left that climbs into the woods. At the next fork, leave the road and take the path on the left (PR® Jaune). At the top of the hill, leave a road on the right and continue to the crossroads with theGR®655.

(12) Follow theGR® on the right down to a road, turn left and enter Thimécourt. Follow this road to the end of the village.

(13) Turn right along the castle. Cross the D922 and continue through the fields until you reach the first crossroads.

(14) Turn right and continue straight ahead to Gascourt. In the street you come to, continue straight ahead (PR® signs). The path makes a detour past the wash house and then joins the road that climbs back up to Luzarches. This part of the path is poorly maintained and is even overgrown after the wash house. Take the road on the left, which climbs back up to the second roundabout from the start and cross over the D316 to reach the car park on the left (S/E).

Notes

Large car park at Luzarches church (just south of the church).
Do not leave the D316 in Luzarches centre (at the bottom of a hill), but take the next exit at the top of the plateau: you will see the church clearly.

Hike done on Sunday, 9 November 2025, with the sun setting on the autumn trees at the end, magnificent, apart from the "hunting in progress" sign. In short, one small detour, otherwise, a beautiful forest with a minimum of tarmac but a view of the castle and pond. In short, a very beautiful hike! Thank you, Visorando!!!

Superb. Spring was in the air, with caterpillars, birds and scents creating a spectacle of a forest in transition, reborn after winter. A few idiots on motocross bikes and others with drones. But nothing could spoil the spectacle of a Silvestre spring. The slopes were ideal for planning other hikes.

a very beautiful hike, most of which takes place in the forest.
The varied landscapes and relief add to the interest of this easy-to-follow walk.
Our GPS showed us that it was over 15 km long.
We really enjoyed it. Thank you to the author.

A lovely hike, pleasant and varied, through woods and countryside. The varied terrain adds to the appeal. Sheltered from the north wind in the woods - 7-8°C during the day with some sunny spells. Keep an eye on your position on the map, as the crossroads are not always marked with signposts. It is possible to cut through the woods and leave the paths. Good for practising map and compass skills!

A very pleasant hike offering varied landscapes
The elevation gain is underestimated given the numerous ascents and descents outside the main ones, which in my opinion are the only ones taken into account

A beautiful and varied hike. The forest is sometimes as beautiful as Fontainebleau.
Same comment as another hiker: point 8 is not really a crossroads. If you're not careful, you'll miss the path on the left.
