Description of the walk

Car park on Rue de la Mairie in Bourg-des-Comptes

(S/E) Exit the car park on the left via the north (town hall on your right), Rue de la Mairie, then turn left into Passage du Tertre, then take thefirst right into Rue de Rondines. Continue to the roundabout.

(1) Turn left onto Rue de la Courbe. Go through the next roundabout, then take thefirst left onto Rue du Moulin de la Courbe. Take the path on the right before reaching the Vilaine and follow it to the footbridge that crosses the Vilaine and lock No. 9.

(2) Turn right onto the towpath, then take thefirst left leading to Château du Gai Lieu. Retrace your steps and take the towpath, keeping the Vilaine on your left, until you reach a small bridge.

(3) Continue along the towpath (with the Vilaine on your left) until you reach lock No. 10, Écluse de la Molière.

(4) Take the small path on the right, just after the lock keeper's house, which turns left, then right to pass under the railway line. Follow this path which climbs through the woods to reach the Château de la Molière.

(5) At a right-hand bend, a small path on the left offers a view of the château (private property).
Turn left into the driveway, then take thefirst driveway on the right a few metres further on. When you see the road opposite (barbed wire), turn left (the ditch is very easy to cross) to reach the small road leading to the château. Turn right onto this road, then left at the next road. Continue straight ahead on the path opposite.

(6) At the building on the left (the path opposite is blocked and impassable), turn right into the field and follow the hedge on the left. At the end of the field, join the wide path via a passage on the left.
Turn left (GR®39) and follow the small road that passes over the railway line. Turn right after the bridge and continue until you reach the D84.

(7) Turn left then follow the road to the right to cross the Vilaine river via the road bridge. Take thefirst road on the right above the leisure area, then take thefirst path on the left (yellow line): avoid the small wooden bridge and take the path entrance in front of it instead. Follow this path with the road on your right.

(8) When you reach a path on the right, go up the stairs on the left that lead to the cave and oratory route. At the top, turn left and follow this path to the Oratory of Sainte-Anne. Turn right twice
and return via the upper lane. Follow the main path to a white metal gate.

If you do not wish to take the cave route (approximately 350 metres shorter), do not take the stairs on the left and continue along the path that leads to the Lavoir du Prieuré. Take the path on the left that goes up after the wash house, and at the end turn right to reach the white metal gate.

(9) Go through the gate and continue straight on to the cemetery lane and continue along Rue des Grottes, which turns right. Cross Rue des Manoirs (pedestrian crossing) and turn left, then take thefirst right onto Allée des Vignes. Continue to the end of this lane.

(10) At the end, follow the path on the right which turns left between two fields to join Rue de Bourg-des-Comptes (D77). Turn left and follow this road for about 1 km. Pass Val de Bas.

(11) Cross the Semmon and turn onto thefirst path on the left, opposite Grand Moulin.
Follow the path slightly uphill, along the edge ofthe second field and alongside the hedge on your left. After crossing a small stream, continue along the path furthest to the right and continue until you reach the small road.

(12) At the small road, you have two options:
- Follow the route: turn left, then take the path on the right atthe first houses (for the cross at the crossroads: a wooden cross, half fallen down and behind a car when I passed by!
Follow this path straight ahead, ignore the path on the left and then the one on the right at the edge of the woods, and at the concrete electricity pole, turn right to join a small road. Turn right at the next road. Turn left onto Le Boschet.
- Or, to save 800 metres: turn right (stone cross on the left of the road to follow). Continue straight ahead until you reach the T-junction, turn left then right towards Le Boschet.

(13) Continue along the small road that passes in front of the Château du Bosche. Follow it to the right in front of the Ferme du Boschet (ignore the path on the left) then follow this wide path to the road. (path that turns left after a pond on the right, view of the back of the château).
Cross the road and continue along the path opposite into the wooded lane.

(14) At the T-junction, turn right, then take the path on the left that passes in front of Château de Mont Rive. At the bottom of the path, turn left, pass in front of the castle entrance gate, then turn left at thefirst house and continue on the road to the right between the houses of La Mussais (sign saying "Give way at 150m"). Continue to the D77. Turn left.

(15) Cross the D77 at the bus stop and, on the left, take the protected path to the footbridge over the Ruisseau de la Chalouzais. Continue along this tarmac path uphill and around a bend to the right. Take thefirst path on the right (wooden barriers), then thefirst on the left. Follow this path to a crossroads (bench on the right and wooden cross opposite).

(16) Turn left to leave the woods and follow a tree-lined lane. Continue straight ahead, with the Château de le Hamonay on your right (barely visible, except for part of the roof, even when walking around it via the Allée du Calvaire) and follow the path on the left when you reach the houses. On the right, head for the Town Hall car park (S/E).

Notes

At least one picnic table can be seen next to the car park below "La Levée".

There are numerous stone benches and small "alcoves" at the bottom of the route, at "la Levée" (after point 7a), which are ideal for enjoying the view and picnicking with two or three people.

With two alternatives at (8) and (12), you can shorten the walk by 1.15 km.

Worth a visit

At point (8), the history of the site is recounted on information panels, and there are benches for resting or picnicking, making it well worth the extra 350 m.

Always be cautious and plan ahead when you're outdoors. Visorando and the author of this route cannot be held responsible for any accidents occurring on this route.

The most interesting part of the route is mainly in the first third.
Luckily we had a GPS, because from stage 5 or 6 onwards, I can't remember which, the explanations were very confusing! We took a wrong turn and ended up on someone's property, where we were given a very hostile reception.
Otherwise, it's an easy route with no particular difficulties, apart from the unclear explanations.

We occasionally used GPS to check that we were on the right route.
The "Levée" in Pléchatel was very original, a beautiful route.

This route would be very interesting, but unfortunately has one major drawback: to cross the Semnon, like the GR 39, it uses the D 77 for about 1 km between Pléchâtel and Bourg-des-Comptes. This section is very dangerous because traffic is very heavy at certain times of day, while the road and hard shoulder are extremely narrow. This route is strongly discouraged, especially for groups.

A very beautiful hike with four castles along the route. Reaching La Molière Castle was not straightforward, but we solved the problem with the help of a compass. We missed an exit at La Chopinais and walked along the railway line to the Pont de Cambré railway bridge and back to Pléchatel along the Vilaine. Be careful on the climb after La Plage, as it is steep. A superb walk.

A beautiful route without any major difficulties.

The option to shorten or extend the distance is very welcome, depending on your fitness level.
The Château du Bouchet looks magnificent in the winter sunshine.

Some sections are moderately interesting (the towpath, from 2 to 4 and the section from 8 to 13). The castles, apart from Boschet Castle, can only be seen from a distance. The distance, approximately 18 km, is a good outing, not too difficult.
There is a pleasant break by the Semnon river, after the Grand Moulin (a large open meadow, shaded by trees).

Hello,
Thank you for your comment. The route was mapped out on site just before lockdown.
I agree that the road section is long and uninteresting, so I'm thinking of finding a solution by joining (if possible!) two sections of path (on the map, to be seen on site) that branch off to the left via "Le Val de Bas".
Otherwise, there is a detour via a smaller road that is certainly less busy, via "la Guesdonnière", and a path that joins the D77 before the "Grand Moulin", but this adds more kilometres!
To be continued when the weather improves.
Serge.

A very beautiful hike completed on 1 May 2021.

However, we were a little disappointed by one section between stages 8 and 11.

First of all, the path passes through uninteresting residential areas. The biggest problem comes next: the route (which follows the GR at this point) crosses the road without any pedestrian facilities. Cars speed past us dangerously, and the enjoyment is gone for a good portion of the way.

Fortunately, a nice hiking trail resumes just after the big mill (stage 11 of the description).

Thank you for this very pleasant route full of discoveries.
