The Devil's Breach

Legend has it that the devil split the plateau to allow access to the church of Saint-Quentin. The Laizon gorge has become a beautiful hiking trail, passing through steep, narrow gorges to the plateaus of the Falaise plain, near the tomb of the actress Marie Joly, the former site of the iron mine, manor houses, castles and traces of prehistoric occupation. The site has been listed since 1974

Description of the walk

Access: Saint-Quentin car park (limited to around ten cars). It can be reached from Soumont Saint-Quentin by taking the D261B, which leaves from the village church and descends towards the Laizon gorge. The car park is on the left just after crossing the Laizon.

(S/E) Take the path opposite the car park on the other side of the D261B towards the Brèche au Diable. Walk 300 metres along the Laizon river and, at the waterfall, keep left, following the yellow signs for the Brèche au Diable trail. The path runs alongside the woods for 300 metres, then crosses them, turning sharply right to arrive at the Saint Quentin chapel.

(1) Take the tarmac road on the left for 50 metres, then take the path that descends to the right to join another path. Continue downhill to the right to reach the Laizon and cross it via a wooden bridge, the Pont du Lavoir.

(2) After the sign for the site, climb the path on the left that winds through the gorge. At the crossroads, turn left to the edge of the forest and follow it on the right for 200 metres, then turn left and right and head towards the farms.

(3) At the crossroads, turn right, then continue straight ahead towards the woods. In the woods, continue straight ahead, leaving the paths on your right and left, until you reach the D261, near an old wood drying building.

(4) Go down to the right for 100m on the D261B, then follow the path opposite which climbs gently towards Ouilly-le-Tesson, following the yellow markings. Pass a water treatment plant.

(5) At the first houses in Ouilly-le-Tesson, turn left and then immediately right to go up towards the church.

(6) At the church in Ouilly-le-Tesson, follow the D261 for 1 km, passing the calvary.

(7) Before a Y-junction, take the road on the right. Go down the road that crosses the Laizon. Continue to follow the yellow signs on the right at the crossroads.

(8) After the farm building, turn left onto the path that climbs alongside the fields, then take the first path on the right that joins the Chemin du Bois des Plaids and leads to the D261A.

(9) Follow the D261A to the left for 100 m, then turn right onto the path leading down to Saint-Quentin. Access is restricted to pedestrians. This path leads to the top of the Chemin du Mont Robert, which winds around the houses of Saint-Quentin and descends to the Saint Quentin road (D261B). Turn right and descend gently to reach the car park (S/E).

Worth a visit

Brèche au Diable sensitive natural area
As part of its policy to preserve and enhance sensitive natural areas, the departmental council has acquired various plots of land to develop the site and welcome the public while protecting the environment. Now a listed site, it is of archaeological interest due to the presence of traces of prehistoric occupation. There are 220 known plant species on the site, including rare and even very rare species such as Moenchia erecta. To protect it, the paths are fenced off. A belvedere is under construction.

Tomb of Marie Joly
Marie-Elisabeth Joly was a member of the Comédie Française, born in 1761 and died at the age of 37. Her tomb can be visited at weekends and is located at the highest point of the site.

Assy Castle
An original façade with four Corinthian columns upstream of the central entrance to the building. "A major work of neoclassical civil architecture in Lower Normandy, the château was built by the architect Gondois in 1788. The architect incorporated the former 16th-century manor house into his design." (Source: Historic Monuments).

Ouilly le Tesson Manor
The manor house is the size of a 15th-century house and has been converted into a farm. However, "two turrets of the entrance building used for residential purposes" remain (Source: Historic Monuments), including a stair tower attached to the building, which bears witness to the wealth of the Ouilly family (15th and 16th centuries, architect Victor Petit).

Sumont Saint Quentin Mine
The largest iron mine in the west. It operated from 1902 to 1989.

Beautiful hike; three-quarters of it in the woods; some fairly steep slopes; very poor signage on site, crossing with other hiking trails which can be confusing
impossible to follow the hike without the GPS track from Visorando

It is essential to follow this route via Maps, otherwise there is a high risk of getting lost.
The part of the route that passes through the forest is interesting and relaxing until you reach the Devil's Gap.
However, the majority of the route runs alongside roads, a few blocks of houses and fields, and offers nothing of interest other than walking, as there is nothing remarkable to see.
Contrary to what can be seen on the internet, there are no signs describing the history of the area.

A very pleasant and beautiful route. Not easy to do without the GPX track, in my opinion. I hike a lot with Visorando and I think this hike should be classified as moderate rather than easy.

A very pleasant route, particularly at the start up to the Brèche au Diable. Parking has been prohibited since a municipal decree was issued in 2023. You therefore have to park in Soumont-Saint-Quentin, at the foot of the church, which adds about 1 km to the walk.
Shortly after waypoint 2, the path you need to take is blocked with a "no access" sign, with no further explanation. We therefore continued along the Laizon on a slightly rough but very pleasant path at the foot of the stream and cliffs, to return to the "start" and then complete the loop in the opposite direction. We therefore did not complete the section between 2 and 4.
It should be noted that a torn barrier tape at the start bears a municipal decree prohibiting access to the area due to a recent fire. However, there was no sign of a fire and on the Mont Joly side, at the exit of the path onto the road, there was no information or signage. Apart from these surprising and sometimes disturbing "prohibitions", the hike is very pleasant, peaceful and offers a variety of landscapes, but a map and GPS tracking are recommended.

A very varied and enjoyable hike
Beautiful scenery. The start along the river is peaceful and magnificent.
Hike with quite a few elevation changes, alternating between woods, small roads and paths
Definitely worth doing

We were alone on the path in sunny weather. At the chapel, you have to enter the meadow to see Mary Joly's grave. It's not far, and the route is very pleasant

A beautiful and pleasant hike with varied landscapes. You might expect flat terrain, but fortunately that's not the case at all.

Hello, I went hiking on 3 November after a rather wet period.
The hike is well marked and accessible to a large number of people. A few spots were a bit damp with some mud, but nothing impassable.
Quite pleasant and bucolic, we enjoyed this beautiful Normandy countryside.

For your information, be very careful with dogs, as my wife and I were attacked. Otherwise, the hike is very nice

A beautiful route with no difficulties and a variety of landscapes: woodland, orchards, rivers and cultivated plateaus. There are few paved roads, and access to Mary Joly's tomb is only possible on Sunday afternoons.

We completed the route from the start at point 4.
A very beautiful hike.
We made a few small changes, then retraced our steps to get back on the route:
- Tour of Saint Quentin Chapel
- After the wash house bridge, descent of the Laizon to the waterfalls
We didn't go to Marie Joly's tomb because we couldn't see where it was. We probably should have continued along the path after the Saint Quentin Chapel
