Description of the walk

Departure from the lower car park at Bassin de la Courance.

(S/E) When you leave the car park, take the road on the right. You will immediately pass the Saint-Sauveur fountain on your left. Then walk alongside the water treatment plant. The tarmac road narrows as it passes through the woods.

(1) Just after the travellers' reception area, below on your left, take the country lane on the left. After a while, just before a grove of trees, you will walk on cobblestones that are believed to be the remains of an ancient Roman road.

(2) Then cross a small wooden bridge and immediately turn right onto the path that runs alongside the Ru de Maurepas. From this path, on a clear day, you have a view (on the left) of the entire Jouars-Pontchartrain plain. Follow this path to the road (D23). Cross it and take the road opposite towards Chennevières and La Richarderie.

(3) Shortly after the first houses in Chennevières, take the first small street on your right (Chemin de la Tuilerie). It turns into a path that you follow to the left, between a hedge and a field, then to the right, turning shortly afterwards into a small tarmac road.

(4) When you reach the large farm (Ferme de Potançon) on your right, take the road (Rue de Potençon) a little further on the left to enter the small village of La Richarderie. At the end of this street, take the cul-de-sac on the right, which turns into a path. Then enter the forest by taking a path on the left that goes uphill and then immediately turns right.

(5) After a while, you will come to a small street that descends to the right (Rue du Moulin Neuf). Take this street and follow it to the small village of Ergal.
Once you reach the main road that crosses Ergal (D23), take this road on the right.

(6) Then turn immediately left onto Rue de la Nouzotte. This road takes you past an apple orchard on the right before turning into a path.

(7) You will come to two barriers. Take the path after the barrier on the right to go alongside the pony club. Follow the path until you find yourself in front of the water treatment plant that you passed at the start of the route. Turn left, then immediately left again onto the path that climbs slightly and takes you back to the Bassin de la Courance, which you will see very quickly.
Turn right onto the path that takes you over the dyke. You will find the car park at the bottom (S/E).

A very pleasant walk, relaxing and a change of scenery.
The countryside is very much in evidence and the hike is ideal for families, novice hikers or dog walkers.
Short but very pleasant

A very pleasant walk combining fields, a small village and forest paths, lasting 2 hours, plus an extra 20 minutes if you walk around the lake to watch the birds.

A very pleasant spring hike, with nature in full bloom, horses, views of Jouars church and its tree-lined driveway... The weather was dry, so there was no mud on the part of the path bordering the fields. We added a short detour to Chennevières and a tour of the Courance basin to make an 8 km hike.

A huge advantage of this route in the current climate is that we were able to set off on foot from our home. A nice little walk. The detour in section 3 is well worth it. There are just a few muddy ruts caused by mountain bikes in places, but nothing too troublesome. The area around the Courance basin is very busy, especially on a beautiful spring Sunday.

We really enjoyed this hike, which we combined with the Petite circular of the Bassin de la Courance. A very pleasant route with holiday-like scenery. Vast meadows with horses.

At number 3, after admiring the pretty red brick castle, continue a little further to discover the picturesque thatched house and walk around it to see the façade along the stream. Only then should you retrace your steps to take the Tuilerie path. However, the pigsty with the pig's head (comment below) no longer exists, as it was demolished by the workers who built the small buildings.

a very pleasant hike despite the heat of the day (bring water... lol At junction 3, it's a shame to cut across rather than go straight on through the village of Chennevières, where you can admire beautiful houses and a magnificent thatched cottage... If you follow a small path, you'll rejoin the route a little further on (the detour is insignificant in terms of kilometres).
we really enjoyed this walk.

A pleasant, varied short walk.
Point 3) Continue straight ahead for 50 metres to admire the beautiful red brick castle, then retrace your steps to take the Tuilerie path
A little further on, on the right, small buildings are being constructed and just next to them, on the left, you will see an old abandoned pigsty (check out the pig's head above the main door, with its tongue hanging out – it's worth a look!).

An interesting walk in an unexpected and very pleasant place! We didn't expect to find such a charming and peaceful spot here. At this time of year, some of the crops are ripe, which, together with the poppies, creates a beautiful mix of colours.
The description and route are good, thank you for this description!
We continued our walk along the 'Petite circular of the Courance Basin' trail.

Thank you for your comments.

It's true that the route isn't particularly interesting, but I was suggesting a short, unpretentious hike.
Thank you for the two "Very good" ratings. I'm trying to do my best as a recent Visorandonneuse.
