Starting point: Chemin de la Chapelle in Rennmoulin.
Access and parking: Rennemoulin is located on the D161 road between Villepreux and Noisy-le-Roy. Once you enter the village, there is a three-way junction with a wash house that can only be seen from behind: turn right if you are coming from Villepreux, left if you are coming from Noisy-le-Roy (signposted "Mairie"). Follow the road downhill to the end and park in the car park signposted along Chemin de la Chapelle.
No signposts
(S/E) With your back to the "Parking" sign, follow Chemin de la Chapelle on the left with Ru de Gally on your right. Continue to Chapelle Saint-Nicolas (not open to visitors). Retrace your steps.
(S/E) Turn left, cross the Ru de Gally and go up Rue du Moulin.
(1) Opposite the wash house, turn left, cross the D161 road at the pedestrian crossing (take care) and follow it on the left. Note the old fountain after number 4 on the street. Go up the stairs on the right and continue along the path. Pass under an arbour and immediately turn right into a slightly downhill street (Chemin de Chaponnal).
Orange markings are rare due to lack of support.
(2) Cross the D161 road (take care) and continue opposite on the path that starts after a forest barrier. Walk along the wall of a property on your right, then descend between the fields. Cross a stream and ignore the path on the right (not shown on the map). Pass a yellow two-sided sign, enter a small wood and climb uphill. At the top of the hill, continue east on a farm track, ignoring a path coming from the left.
(3) At the crossroads (yellow two-sided sign), go straight ahead along a path between the fields. At the next crossroads, continue straight ahead along a gravel path. Further on, cross a small road and continue along the gravel path.
(4) As you approach a row of trees some distance to the right, note a path coming from the right (which you will take later) and continue straight ahead to a T-junction. The Maltoute Fountain is located below on the right, at the foot of a weeping willow.
No markings
(5) Retrace your steps for about a hundred metres.
(4) At the fork, take the path on the left (the one you noted earlier). Walk between the Ru de Maltoute on your left and a reed bed on your right. Just before a system of sluice gates on the stream, turn right, go down a few metres and then continue along the stream on your left. N.B. The path is not shown on the map, which indicates a path on the other bank, but this is inaccessible as it is located on private property.
(6) Come out onto a small road and follow it to the left after crossing the stream. Ignore a turn-off on the left and take the access road on the right to the Moulineaux equestrian centre. Just before the bridge over the Ru de Chèvreloup, turn left onto a farm track with a horse pasture on your left. Follow the track in a right-left zigzag to cross the Ru de Chèvreloup just before it joins the Ru de Gally (much wider).
(7) Continue westwards along the Ru de Gally on your left. At the bridge on the left, turn right onto the track. Go uphill, head north and rejoin the crossroads you took on the way out.
Orange markings are scarce due to lack of support.
(3) Turn left, descend into a small wood, climb slightly, follow the wall of a property on your left and reach a forest barrier.
(2) Turn left onto the D161 road.
(1) At the fork, veer left and pass in front of the wash house. Continue along Rue du Moulin to quickly return to the starting point (S/E).
, we brought back a lot of TICKS, and as this small section was the only one that was off the beaten track and fields, it is surely the part responsible.
