The Viosne Valley around Chars

A pleasant and varied hike in the heart of the French Vexin. The route begins with a circular route north of Chars, between fields, meadows and small woods. After the beautiful church of Chars, there are alternating ascents and descents on the slopes of the south bank of the Viosne. The church and old mill in Brignancourt are a heritage stop before heading up the right bank of the Viosne along the edge of a wetland.

Description of the walk

Starting point and access: Chars railway station .
- Transilien - Line J, on the section between Paris-Saint-Lazare and Gisors.
Take the only exit, on the platform in the direction of Paris to Gisors (if arriving in the opposite direction, take the footbridge).

Yellow + red and white markings

(S/E) With your back to the station, turn left and walk past the simple war memorial. Continue straight ahead until you reach the intersection with Rue de Gisors (D915).

Yellow markings

(1) Cross the D915 and follow it to the right. Cross Rue de la Groue on the left-hand side. About 50 metres further on, turn left onto a slightly downhill path. Walk along a wall on your right and, on your left, gardens and then a meadow. At an intersection, continue straight ahead and walk along a fenced meadow on your left. The path narrows and becomes surrounded by vegetation. Come out onto the D188.

(2) Follow the road to the left, immediately cross the VC2 on the left-hand side and follow the main road due west. Please note that after the Chars exit sign, the hard shoulder is narrow and unmaintained (as of June 2021): remain very cautious; you can walk along the edge of the field on the left-hand side, taking care not to tread on the crops.

(3) At a left-hand bend in the road (pond), turn right towards a farmhouse. Pass between the buildings (attractive gate on the right-hand side) and continue along a farm track. Further on, turn right along the track and ignore the grassy path opposite, which is not shown on the map. Walk along a small wood on your right, join the D915 (forest barrier) and follow it to the right, protected by a guardrail.

(4) At the end of the guardrail, turn left to cross the road (good visibility). Continue along a path on the edge of the woods on the left. When this wide path turns left, continue straight ahead (east) on a grassy, downhill, shaded path. At a crossroads (elevation 87), continue straight ahead and descend into a wood. Return to the tarmac (damaged stone cross on the left-hand side) and turn right.

(5) At thefirst intersection, turn left towards the Étangs de Chars. Cross the Viosne. At the next three-way junction, at the corner of a pumping station, turn right uphill. After a hundred metres, at a fork, take the right-hand path into a shaded cul-de-sac. Further on, ignore a turning on the left. Then walk alongside some gardens and a railing on the right-hand side. At a T-junction, turn left and climb a staircase. At the top, turn right and walk down a street. Enter Chars and you will come to an intersection at the foot of the church.

(6) Then follow Rue de la Gloriette to the left. Further on, cross Rue de Marines at the pedestrian crossing on the right. First turn left then right to continue along Rue de la Gloriette, going downhill. At the bottom, follow Rue André Baleydrier to the left. At number 33, turn left and go uphill along Sente de la Maladrie.

At the top, go through a chicane and ignore a turn-off on the left. Then turn right onto Chemin de la Maladrerie and walk along a housing estate on your left. Further on, ignore the access to a private property on the left and descend slightly onto a grassy path. Continue along a staircase. At the bottom, follow a road on the left that immediately turns right.

(7) After about 100 metres, leave the road and take a path on the left that climbs into a wood. At the top, continue south-east between the fields. At an intersection (elevation 93), turn right and walk alongside a fenced wood on your left. Enter the wood, descend and note a troglodyte cave on your right. Go through a forest gate and you will come out onto the road you left earlier.

(8) Follow the road to the left (south). Further on, enter Brignacourt. At a fork, keep right and arrive at the foot of the church.

No markings

(9) Turn right (ignore the signpost on the left) and pass the church entrance. Note a large building opposite (an old water mill) and turn left into a street with a 30 km/h speed limit. Walk along a small square on your left and you will come to a stop sign.

Red and white + yellow markings

Turn right onto Rue de la Viosne, pass a wash house on your right and cross the river. Then cross the railway line and turn right with the road, staying on the right-hand side (better visibility). Ignore the access to a meadow on your right.

(10) Shortly afterwards, turn right onto a path that starts after a forest barrier and descends gently. Then walk along flat ground, keeping to the right of a marshy area (note the specific vegetation of wetlands). At the T-junction at the corner of an isolated house (elevation 62), turn right. You will soon reach the Moulin de Noisemont.

(11) Continue straight ahead (north). After about 200 m, take a wooden walkway on the right that leads to a wooden footbridge over the Viosne (a good place to stop for a break).

(12) From the footbridge, take the right-hand branch of the wooden walkway to rejoin the main path. Continue north-north-east through a beech forest. You will rejoin the tarmac road at a place called Panama.

Red and white markings

(13) Between No.64bis and No. 64, turn right and walk along a water treatment plant on your left. Pass a chicane, continue on a path and cross the Viosne. Then turn left and follow a path between gardens on the left and the railway line on the right. Pass the agricultural silos and, at a stop sign, go straight ahead.

Red and white + yellow markings

At the next crossroads (level crossing on the right), turn left.

(1) After about 50 metres, turn right onto Rue du Général Leclerc. Continue straight ahead to Chars station (S/E).

To return home:
- Transilien - Line J, towards Gisors (direct access) or Paris-Saint-Lazare (take the footbridge).

For motorists: park in the car park at Chars station, at the end of Rue du Général Leclerc.

Hiking boots are recommended. The route crosses several wetlands.

No water sources identified along the route. Bars, restaurants and small shops in Chars (1).

A 1:25,000 map is useful (at least the one accompanying this description).

Hike completed in August 2025.
On leaving Brignancourt, after the wash house, there is a picnic area on the left.

At point 10, in the woods in a marshy area, the path was impassable due to mud. Climbing up the embankment on the left, you quickly come across a parallel path to avoid the muddy areas, but you have to be able to pass under branches, over trees, and hold on here and there. It's a bit of an adventure.

A varied, easy and enjoyable hike. Surprisingly, there was no mud near the Viosne. Passing through the north of Chars offers a beautiful view of its church. There are a few benches on the church square and two slightly further back near an old well for a more peaceful spot.
Thanks to Netra for this perfect description.

Hello and thank you for this map.
The only downside, for which you are not responsible, is that the beautiful church in Chars is closed.

Varied route, many sections of road (with little traffic)
Recommended hike
It's a shame that the description is sometimes too long and confusing.
Example:6 Just say
Follow Rue de la Gloriette to the left (be careful when crossing Rue de Marines) until you reach Rue André Baleydrier
