Paris Day Trips: Follow the Morbras River Around Sucy-en-Brie

The great attraction of this little-known walk around Sucy-en-Brie is that it combines some unexpected glimpses of wildlife with buildings of historic interest, just 29 minutes from Châtelet les Halles with trains every 10 minutes.

Sucy-en-Brie is situated between the River Marne and the edge of the Forêt de Notre Dame, partly encircled by two streams which flow into the Marne. The canons of Notre-Dame de Paris were the seigneurs of Sucy and the surrounding land from the seventh century until the Revolution and until the late 19th century it remained an agricultural village with a small population. In the 17th century a few Parisian families built châteaux de plaisance there, attracted by this bucolic spot only 22 kilometers from the capital. Madame de Sévigné spent part of a happy childhood in one of them. It was the coming of the railway in the 1870s which led to a population explosion and eventually transformed Sucy-en-Brie a century later into a suburb of Paris on the RER A train line.

But the old village with its narrow streets clustered around the 12th-century church is the heart of the modern town and there is a new appreciation of its historic value, visible in its recent restoration and partial pedestrianization. Four of the original six châteaux are still standing, although put to other uses, and many green spaces have been preserved as public parks. The 19th-century fort on the edge of town is accessible to anyone who cares to wander inside. When normal times return I will be trying out the Bistrot du Fort nearby. This restaurant and the café next to the station are open on Sundays, which is a big plus as far as I am concerned.

8½ km walk around Sucy-en-Brie

This walk mostly follows the GR route.

On leaving the train take ‘Sortie 1, Place de la Gare’. Cross the road diagonally to the left towards the pharmacy with its green cross, on the corner of Rue Montaleau. A baker and a small grocery store in between the café and the pharmacy are useful sources for picnic supplies, open on Sundays.

Follow Rue Montaleau uphill and take the third left into the Rue de Sévigné, past a distinctive house with a cupola.

Madame de Sévigné, who was orphaned at the age of seven, spent part of her childhood in the Château de Montaleau, the home of her grandfather, Philippe de Coulanges. The château is on the hill at the end of Rue Montaleau and you will pass it on the way back. It now houses the Tribunal d’Instance, the magistrate’s court.

Turn left into the Rue de Sévigné and then right into the Rue des Fontaines. Take the first left onto a rustic little GR footpath, the Sentier du Vieux Val, which winds around people’s back gardens, one of them containing a few inquisitive hens.

At the end of the path turn right onto the Rue Maurice Berteaux and continue uphill to the traffic lights. Cross at the pedestrian crossing and take the first left into the Rue Raspail. At the end of this street cross the Rue Thiers onto another little GR footpath straight ahead and continue to the Rue Chevreuil. Turn right and keep straight on down the Rue Pasteur until you see a pond with a bench, overlooking an islet accessed by a footbridge, a favorite place for ducks. The pond is grandly named the Lac du Grand Val and is fed by the Morbras. A bras mort, literally ‘dead arm’, means a backwater.

After a while if you look hard at the islet you will probably spot a coypu or two, camouflaged by their color to blend into the water’s edge. In fact on my recent visit we saw so many that we named the islet Coypu Central. A coypu looks like a cross between a beaver and a large water vole. Originally brought to Europe from South America to be bred for their fur, coypu are now considered an invasive species and have been eliminated in England, although not yet in France where the word for them is ragondin. The ones in Sucy were absolutely fearless and came out of the water to nibble the grass only a few feet away from us and some passersby.

Turn left from the bench and follow the water right round to its end on the opposite bank, where you will see a pedestrian crossing. Cross it and look up to see steps above you. Climb these and turn left, over a small bridge across the Morbras which cascades noisily here over a little weir. The entrance to the Parc du Morbras is a little further, on your right.

The Morbras flows through the bottom of this park, which feels beautifully untamed although it has a children’s playground, two picnic tables and is overlooked by some houses. I first visited it in November, when it was deserted and covered with colchiques, wild autumn crocuses, a rare sight in urban areas.

On my February visit it was full of planted spring crocuses and local people enjoying the sunshine but the parts near the river still felt more like the countryside than like a park. Take the lower path close to the Morbras and follow it for the length of the park and through the inevitable car park to the exit.

Turn right and follow the road downhill, cross at the pedestrian crossing on the left and turn right into a busy road, the Avenue Maurice Schumann. Follow it across the Morbras and left into the Rue de Noiseau. Cross the road here and take the GR footpath on your right into a wood bordering a little stream, the Rû de la Fontaine Villiers. Follow the stream on your left for just over a kilometer, through a kind of straggling park, frequented by locals. The footpath forks at the end, from where you can see the D136 ahead.

Take the righthand fork and follow the path until it ends at a small road, the Avenue de la Fontaine de Villiers. Continue along the road for a few meters to a pedestrian crossing. Cross and follow the footpath straight ahead under pine trees, parallel to the busy main road, Avenue Charles de Gaulle. You will eventually come to a roundabout and a restaurant on your right, Le Bistrot du Fort. I have never tried this restaurant which is of course closed at the moment but its terrace and traditional French menu look promising.

Continue along the main road and take the first right, an unmarked footpath which follows the moat around the Fort de Sucy on your right and leads straight to the entrance. The fort was one of a series constructed to defend the capital between 1879 and 1881 after the disastrous siege of Paris by the Prussians in 1870. It did not play an active part in the First World War and was occupied by the Germans for most of the Second World War.

They blew up their munitions and part of the fort before their retreat in August 1944, but enough is left to give you an interesting glimpse into late 19th-century French defensive architecture. It is managed by a voluntary association who dress up in period military uniforms for the free guided tour at 3 pm on the first Sunday of each month. I happened to arrive at the right time on my first visit and found the little museum inside rather touching. It is closed at the moment but you can always wander round the fort on your own. On my recent visit, one of the courtyards was being used for practice by a local archery association, which seemed fitting.

Turn left from the fort entrance and return along the Allée des Douves towards the main road, Rue Ludovic Halévy. Take the GR woodland footpath on your right which parallels the main road and continues past some attractive old buildings. This walk is used by local people walking their dogs and astonishingly, given the busy road close by, we saw an even noisier woodpecker which was attracting everyone’s attention above our heads.

The footpath leads to a car park and passes a handsome 17th-century building now used as the salle de mariage for civic weddings. It was formerly the Château de Haute Maison. After 1893 it was the home of Ludovic Halévy, the librettist of Carmen, and his family who entertained many distinguished visitors there.

Cross the main road ahead of you, the Avenue Winston Churchill, at the pedestrian crossing into a quiet little street straight ahead, still the Rue Ludovic Halévy, into the heart of the old village. Turn left into the Rue Guy Mocquet, follow it round to the right into Rue de la Porte, whose name recalls the town’s former ramparts, and turn left into the Rue de Boissy. The Eglise St Martin is on your right. Go round it to your right to find the entrance.

I have always found this church open and it has a very peaceful atmosphere, perhaps because it has stood here for so many centuries. There seems to have been a church dedicated to St Martin on this spot since 811 although the earliest parts of the present church date from the 12th and 13th centuries. In 1793 three of its four bells were melted down by the revolutionaries to make cannon but they left the biggest one, called Martine, which dates from 1658. Three more have been added since 1997.

Turn right from the church into the Rue du Moutier. At the end turn left downhill into the busy Rue Pierre Semard. Continue downhill past the Tribunal de Proximité on the right, the former Château de Montaleau owned by Madame de Sévigné’s grandfather, which dominates the hill.

Cross at the pedestrian crossing and take a path straight ahead, indicated by a sign for the car park reading ‘P Montaleau (sous-sol)’. Follow it past the château on your right and turn left to go through the park along a straight path leading downhill. You will eventually pass a stretch of water on your right and soon afterwards the path becomes the Rue Montaleau. Continue downhill, past the house with the cupola on the corner of Rue de Sévigné which you passed earlier, to return to the station.

RER A trains to Boissy St Léger run every 10 minutes from Châtelet les Halles, taking 29 minutes to Sucy-Bonneuil. Details here.
