Petit Morin Valley - Orly and the Moulin de Coton

A circular route on both banks of the Petit Morin. On the way there, you climb up to the plateau on the right bank and walk through meadows, woods and cultivated fields. On the way back, you follow the Petit Morin on its left bank, often along the edge of the woods. Two churches, a wash house and an old mill are worth seeing along the way.

Description of the walk

Parking on the Place de l'Église in Orly-sur-Morin (on the D31, 12km south-west of La-Ferté-sous-Jouarre and 20km north-east of Coulommiers). For access by public transport, see the practical information.

Yellow markings

(S/E) Take Rue de l'Hêtre (sic) towards Sablonnières. Cross Ru de la Fonderie and walk along a triangular square on your right. Before leaving the village, turn left onto Rue du Chêne Madame. At the end of the street, continue north-east on a grassy path that climbs gently, winding between the meadows. Enter a wood, where the path becomes wider. Ignore a smaller path that branches off to the left and, after a bend to the right, you will come to a small road.

No markings

(1) Leave thePR® on your right and take the road on the left. As you leave the woods, you will see a large farmhouse to the north-east. Leave the farmhouse on your right and continue along the tarmac road. At the fork, turn right and you will immediately come out onto the D55.

Yellow markings

(2) Turn sharply right and follow the road to the village of Boitron.

No markings

(3) At the entrance to Boitron, ignore the yellow cross, walk past the cemetery and enter the village. Continue along the main road (due south).

(4) Turn left onto Rue des Moines. After a few metres, take the street on the left and then immediately turn right onto a narrow tarmac road heading due east. Follow this road across fields for about 1.2 km, ignoring a road that branches off to the right at elevation 182.

(5) When the tarmac ends, turn right onto a grassy path between two plots (there is a clump of trees in the middle of the left-hand plot). Walk along a meadow, descend slightly and you will come to a small road.

Yellow markings

(6) Take the road on the left. Cross a small wood and then the hamlet of Marlande.

(7) On leaving Marlande, just before the road sign, take a street on the right and walk alongside a house with a well. Continue along the path that runs alongside a meadow on the left. At the next fork, do not take the path opposite that goes down into the woods, but turn left and continue along the meadow. You will reach the hamlet of Jariel.

(8) Take the road on the right. After a few metres, when the road bends to the left, continue straight ahead, slightly to the right, into a street with a house with bright blue woodwork and ironwork. Pass the house: the village of Sablonnière appears lower down on the left. Continue south, descending between the meadows. Pass a yellow arrow on a fence post (the indicated turn is further down) and come out onto a perpendicular path.

(9) Turn left and walk towards the houses. Take the road on the right that descends towards Sablonnières. At the junction with the D31, turn left. Walk past the war memorial and cross the bridge over a river (wash house on the left).

No signposts

(10) Turn right onto the D222 towards Rebais and cross the Petit Morin.

(11) Opposite the cemetery, just before the sign for "La Chenée", turn right onto a path that heads west along a field. Pass the fenced-off buildings and then a small house at the crossroads. Continue along the same path, which curves north-west and runs alongside a circular section of the Petit Morin. This leads to a wider path.

Yellow markings

(12) From this point onwards, the path is none other than the platform of the old railway line in the Petit Morin valley: it is therefore wide and fairly flat. Take this path on the right. Ignore a smaller path that branches off to the right and then runs alongside the main path, which you should stay on.

(13) At the hamlet of La Forge, cross the road and continue straight ahead on the wide path. You will arrive at Coton, on the banks of the Petit Morin.

(14) Just after passing the old mill on the opposite bank, take the road on the right. Follow this road for about 250 metres (note the old small station on your left). When the road bends to the right to cross a bridge over the Petit Morin, take the wide path opposite, which starts just to the left of the "St-Georges" sign. Continue along the wide path, heading north-west, along the edge of the woods.

(15) At Moulin du Pont, at the fork near the houses with fences, take the right-hand path (signposted "Orly" on a fence post). After a few metres, leave the wide path and take a path on the right leading to a footbridge. Cross the Petit Morin river on the footbridge. At the end of the footbridge, turn left onto a grassy path.

(16) Cross a small road and continue straight ahead (north-west) on a grassy path. You will come out onto a small street that climbs for a few dozen metres. At the intersection, turn right. Immediately afterwards, at a small triangular square, take the left-hand lane. Then turn left onto Rue de l'Hêtre (D31) and continue to Place de l'Église (S/E).

Notes

To reach the starting point by public transport:
Take the train to La Ferté-sous-Jouarre station (Transilien line P), then take the Pays Fertois bus, line 34, and get off at the "Orly-sur-Morin Mairie" stop. For information and timetables, visit the Transilien website and the Transdev Marne-Morin website.

Bakery in Orly-sur-Morin, between the church and the Ru de la Fonderie.
A 1:25,000 map is required (at least the one accompanying this description).

During the hunting season (approximately from late September to late February), the area must be shared with hunters.

In wet weather, the ground is very muddy and, between and (12), the path may be flooded (the place known as "La Bourbière" is aptly named). For these two reasons, this hike is best done in spring or summer.

Alternative route in wet weather:
After the bridge over the Petit Morin, pass the "La Chenée" sign. Immediately after this sign, before the road turns left, turn right onto a wide, stabilised path that runs alongside the old Sablonnières railway station on the left. Go around the fenced-off installations on the left and head towards the woods. At the crossroads at the entrance to the woods, turn right (yellow cross). Walk down a few metres and take the first path on the left, which is the old railway embankment. Follow this path west then north-west and rejoin the route at the point (12).

Worth a visit

In Orly-sur-Morin (S/E):
Saint-Pierre and Saint-Paul Church (13th-19th centuries).

In Sablonnières:
- Wash house at the junction between the D31 and D222 (10).
- Off the trail, Saint-Martin Church (12th-20th century), featuring a bas-relief depicting the scene where Saint Martin shares his cloak. At the point (10), continue on the D31 towards the village of Sablonnières, until you reach the church located on a square set back from the road, on the right. Then retrace your steps and, at the crossroads (10), turn left.

At La Forge (13):
Information panels on the Battle of Petit Morin (6-9 September 1914), before crossing the road and arriving at Coton, near the old mill.

Old Coton mill on the right bank of the Petit Morin (14).

Information panels on the wildlife of the Petit Morin between (15) and (S/E).

Within the Île-de-France region, the Petit Morin valley is a preserved area with a strong rural and agricultural character. This hike is part of a series of routes lasting between 3 and 4 hours, covering the small roads of this charming valley and the communal paths where motorised vehicles such as quads and 4x4s are prohibited (see below for the URLs of the other hikes).

The first part, which leaves the Bois de Boitron and crosses Petitvilliers to Marlande, is, in my opinion, of little interest and uses too much tarmac road. Perhaps it is better to take the PR to Marlande...

Start the route from the end, walk back the last 5 km through the woods to the road, then turn around: you will have covered the most interesting part of this otherwise uninteresting hiking route.
Yet the Morin Valley is so beautiful in the spring sunshine. Bad luck for this route...

As most of the route is on roads (approximately 5 km).

A pleasant walk in fine weather.
A bit too much tarmac road.
On the other hand, the paths are clean.

The first part north of Orly is not very pleasant: tarmac roads with no shade.
But the second part in the Morin valley is excellent!

Hello Netra.
Thank you for these clarifications.
I realise that writing about a hike is a delicate task and, above all, subject to possible changes. Especially since Seine-et-Marne is constantly changing!
If the next Visiorandonneur could confirm or deny what I've said, that would be helpful.
Kind regards
Alain

Hello Penmarch77,

Thank you for your feedback and comments!

For the description in points (3), (4) and (11), I probably need to simplify the sentences: I'll take a look at that.

For the section after point (1), at the farmyard, I chose this path because it allowed me to route around a stretch of tarmac road. At the time (December 2014), there were no barriers, no fencing and no indication that it was a private road. I even passed through when there were a number of people in the farmyard (a gathering of hunters) and no one said anything to me.

Is this actually a private road? If so, does the owner want to make it clear that he does not want people to use it? I am not going to use it again in the near future, and I am not going to take the time to check with the local council. I will probably change the route: it will mean a little more tarmac, sorry...

A pleasant hike, but one that doesn't allow us to enjoy the little Morin enough. Too much tarmac for my liking: I think more than 3 km in total. The hiking time of 4 hours 25 minutes is very generous, as it all depends on each person's pace! I think 3 hours 50 minutes is more realistic.
Three clarifications on the description:
"(1) Leave the PR on the right and take the road on the left. As you leave the woods, you will see a large farmhouse to the north-east. Just after passing the farmhouse, turn right onto a path between cultivated plots (do not take the first path on the right that leads into the farmyard and ignore a yellow marker on an electricity pole that invites you to continue on the road to the village)." The path is blocked by an electric wire, which you will need to cross.

"(3) At the entrance to Boitron, ignore the yellow cross and walk along the cemetery, turn right and enter the village. Continue along the main road (due south).
(4) Turn left onto Rue des Moines. We were confused by the instruction to turn right, as this is the natural direction of the road, i.e. a bend. In fact, after the cemetery, you should continue until you reach Rue des Moines on the left.

"(11) Pass through the hamlet of La Forge. At the exit of the hamlet, cross the road and continue straight ahead on the wide path. Arrive at Coton, on the edge of Petit Morin." You don't pass through the hamlet of La Forge, and it's not really clear that you're at the exit. In fact, you just need to cross the road! And follow the signs.

Enjoy your hike!

Thank you, odduck, for these detailed comments!

Thank you for the information about the blocked communal road. I imagine it's in front of the farmhouse just before the point (2).

As for the mosquitoes, they are everywhere in the forests of Ile-de-France this July, after the exceptional rainfall in May and June.

The route is very good, divided between countryside and forest, with very few tarmac roads. For me, it's one of the best in the area.
However, here are a few things to note about two points on the route:
- Bring mosquito repellent for the Boitron forest...
- At the farmhouse, the owner of the field has put up a cable to "block" access to the path. According to information from the town hall, the VC still belongs to the town hall, so don't hesitate to go over the cable.
- At Jariel, be careful not to take the small path on the right. Instead, take the road with the "Attention chevaux" (Beware of horses) sign. It looks like you're entering a property, but the path actually goes right past it.

Here are my journey times:
- Departure 10:47 a.m.
- 1: 11:08
- 2: 11:19
- 3: 11:30 (2-minute break)
- 4: not taken
- 5: 11:53
- 6: 12:00
- 7: 12:10
- 8: 12:22
- 9: 12:47 p.m. (5-minute break)
- 10: not taken
- 11: 1:15 p.m. - Lives up to its name
- 12: 1:37 p.m. (Break: 2 min) - Mill not accessible - access closed by gate
- 13: 14:00
- Arrival: 14:13

Total approx.: 3 hours 30 minutes

Monday, 18 April 2016 - a beautiful hike in two circular loops in sunny weather:
in the morning, Orly sur Morin/St-Ouen, the castle and the lock, Moulin des Brus/Orly sur Morin, 8.8 km
In the afternoon, Orly sur Morin, the Boitron woods, the vineyard and return via the Coton mill, 9.5 km
Easy route except between 2 and 3 steep descents with rocky and wet terrain, but not impossible
Very beautiful scenery. We will do it again with a group on 17 June.

Good evening, sandrine77,

Thank you for your reply. First of all, I would like to point out that these are wet areas, not muddy ones. This is important because we are talking about a hike taken at the end of August...

As for the location, hunting dogs move around, but a house with a well does not, and on this hike, it is located after the hamlet of Marlande, between WP (7) and (8): is that correct?

If so, I can see what it might be. In winter (when I did the hike), the path that descends from elevation 143 (which we don't take) was dripping wet. You turn left at this point, but in winter it was very wet. And it's possible that the passage of agricultural or forestry machinery doesn't help matters.
