Circular route between Sillon and Marais in Saint-Etienne-de-Montluc

This hike takes place mainly on roads, but these are fairly quiet to very quiet. It follows sections ofthe GR®3and a few farm tracks. The hike offers some clear views from the heights of the Sillon de Bretagne (you can even see the Loire). There are also some interesting buildings to see along the way...

Description of the walk

The suggested starting point is the car park of the restaurant "Le Chêne Creux", located on the D17 between Saint-Etienne-de-Montluc and Couëron.

(S/E) At the far end of the car park, on the level crossing side, cross the D17 and take the small road marked as a dead end at the Lila bus stop. Cross the hamlet of Le Chêne Creux to reach a road, then turn left.

(1) After about 500 metres, at the cross, follow the road to the right (towards ZAC Clair de Lune).
After 1 km, at the crossroads, continue straight ahead. A little further on, on the left, is the Moulin de Bel-Air.

(2). Continue for 300 metres, the road curves to the right, and shortly afterwards, theGR®3turns onto the path on the left. Take this path. Follow theGR®.

(3) Cross La Petite Juliennais. At the end of the hamlet, take the path that descends to the left (offthe GR®). At the bottom, follow the road to the right. After 400 metres, rejoin theGR®3on the right on the path that climbs alongside the houses to the Berliquet stream.

(4) It is usually necessary to walk through the woods above the stream for about 100 metres to cross it and continue on theGR® on the path that climbs uphill. After about 400 metres, at the crossroads, take the path on the right to reach the hamlet of La Roulerais and continue to the stop sign. Follow theGR®3on the left on this road for 300 metres.

(5) Just before the reservoir, theGR® trail branches off to the right. The hike includes a short 500-metre detour (plus return) along this path to reach the "La Grande Juliennais" pond and enjoy a beautiful view of the castle. This is optional.

(6) Return to the reservoir.

(5) Continue down the road to the roundabout. Continue straight ahead on Route de la Clunais, then after 50 metres, turn left onto the path between the farm buildings and continue along this path for about 1 kilometre until you reach the road. Turn right. At the stop sign, cross the road.

(7) Cross the level crossing and immediately take the path that runs alongside the railway line on the left. After about 600 metres, take the path on the right and follow it to the road. Follow the road to the right, then after 50 metres, at the fork, turn left to the hamlet of "La Guillaumière".

(8) Continue straight ahead towards "Les Ouches", then continue to the crossroads towards Le Carrefour.

(9) Follow this direction to the left.

(10) After about 1 km, you will see a beautiful old mansion (15th century) on your right, which is said to have been a hunting lodge for the abbots of Buzay.
Continue to the next crossroads.

(11) Turn left. Follow the winding road.

(12) At the give way sign, continue straight ahead until you reach the level crossing and then the car park (S/E).

This route has the merit of existing in this area, even if there is far too much road for my liking, especially since there seem to be alternatives according to DOMYRANDO. It might also be useful to add information about the percentage of trail and tarmac in the route description.

Beautiful hike
Best done in good weather, as part of the route can be very wet in rainy conditions (stream to cross + subsequent climb up a sunken path)
Storks can be seen on all the electricity pylons at the end of the hike in the lower part.

A very beautiful hike through the countryside, woods and hamlets. At this time of year, we saw lots of daffodils blooming in the woods. Despite the lack of rain, some paths were practically flooded. The village is also very pleasant to walk around, with its old streets and alleys and beautiful houses. I did this hike using alternatives from another site, so there was little tarmac. View of the Loire in the distance. I would do this again in the summer as I think most of the paths are in the shade.

A fairly classic route with quite a few roads. It seems to me that the road/path ratio could be improved depending on the map and the paths encountered. I will suggest some changes once I have tried out my variations.

A very pleasant hike, despite the sections of tarmac road. It alternates between open and covered passages. As indicated in the description, there is little traffic, and it is possible to adapt the walk with other existing circular routes.
