Description of the walk

Park in the Loiry car park.

(S/E) Take the path through the Parc du Loiry, pass the canoe club and reach the banks of the Sèvre and theGRP® Sèvre et Maine.

(1) Take it to the left, following the red and yellow markings. Then walk alongside the racecourse until you reach the bridge over the D105 road.

(2) Go under the road, reach the banks of the Sèvre, turn left to reach the village of La Ville Bachelier.

(3) Turn left, then keep to the right on theGRP®. You will reach the junction of the twoGRP® routes: the Sèvre et Maine and the Pays Nantais.

(4) Keep to the right on the Sèvre et MaineGRP® to reach the Institut des Hauts-Thébaudières.

(5) Go round it on the right and continue along the banks of the Sèvre until you reach the D59. Follow it on the right to reach the bridge.

(6) Cross the bridge, then a few metres further on, leave the road and continue left onto the GRP®. Head towards the village of Bourchinière, specifically the La Péraudière district.

(7) Follow the D59 for a few metres, then leave it and turn left into Rue des Ouches. At the end of this road, continue along the path; this is still theGRP®. Heading due south, reach the junction with the D59 just before the Croix de Brosse.

(8) Turn right here; you will immediately come to the Croix de Brosse. Turn left onto the path and continue until you reach the sports grounds at Saint-Fiacre-sur-Maine.

(9) Leave theGRP® here and walk alongside the sports grounds, first on the right then on the left, until you reach the Maine. Cross it via the bridge. Then turn left to cross the tributary of the Maine via a wooden footbridge. Continue along the path to reach the village of Ronzeray.

(10) Turn right towards the hamlet of Le Petit Clos. Cross the D76 and then Rue du Moulinier. Continue straight on along the path through the vineyards. Carry on along this main path until you reach the Ruisseau de l’Aunay.

(11) Cross it, continue on to reach the entrance to the estate, then turn left at the end of the path. Walk alongside the vineyards, then join theGRP® Sèvre et Maine circular tour of the vineyards.

(12) Turn right onto it and head towards the village of Les Avineaux. Stay on theGRP® trail, following the red and yellow markings. Continue on to reach the village of Portillon, then head towards the crossroads where four roads meet.

(13) Take the small road on the left, running parallel to the main road. Leave this to take a small path on the right and walk along the stream. Follow the path as it climbs between the vineyards. You will reach the junction at Impasse des Brianderies.

(14) Turn right here, cross the village of L'Herbray and continue along Rue du Moulin de l'Herbray until you reach the junction with Route de la Frémoire.

(15) Turn left onto this road, running alongside the vineyard, then turn left onto Chemin de la
Mesangère. Then leave this path and turn right onto Chemin des Haies to reach Route de la Frémoire once more.

Hello, the route is fine, but it’s difficult to follow on a phone; it lacks detail. The first 8 km are quite busy. The walk takes about 4½ hours. Best regards, Yves

I wanted to try walking the section between waypoints 13 and 14 (between L'Herblay and Portillon) in the opposite direction, so 14 to 13. It started well, but then the path disappeared and became impassable; it probably needs to be revised, as the detour involves joining the GR du Pays Nantais. In my view, this part of the route needs to be reviewed.
(14 July 2025) My little 6 km walk turned into 10 km...
This countryside, a mix of urban and rural, is actually very disappointing.

A pleasant walk.
The last section is less interesting, with paths that are rutted or littered with branches (Portillon area)

A very pleasant walk along a variety of well-maintained paths, with lovely vegetation and a few sections through vineyards. A lovely surprise in this area, which offers plenty of walking options.
One comment, however: from our point of view, the final section from Portillon is of little interest to those already familiar with the area. Another option to finish this lovely walk could be to cross the bridge on the left-hand side from Portillon, heading towards Vertou. Once you’ve crossed the Sèvres, head towards the racecourse via the steps on the left at the side of the road. Then follow the Sèvres towards the Chaussée des Moines until you rejoin the path taken on the way out near the canoe club and return to the starting point.

There’s a problem with the route at point 9: turn right instead of turning left.
Perhaps also earlier in the route, as I found myself going the wrong way, which ‘cost’ me 1 km before I realised. You need to check the route on your smartphone regularly, otherwise you risk taking a longer route... But perhaps it’s also a question of the hiker’s reliability...

An excellent hike. Lots of lovely paths and varied scenery. There’s a lack of signposting from Le Portillon onwards, but the route map is well drawn.
