Description of the route

Set off from the small car park on the right, Rue du Port Jacquet, at the junction with Rue de la Feuillade.

(S/E) Follow Rue de la Feuillade, then turn left onto Rue Lepesant. Continue left onto Rue des Vallets.

(1) At the junction, turn right onto Rue du Port Jacquet, continuing along Rue de L’Isle and then along the cycle path running alongside Boulevard de la Côte d’Émeraude and Boulevard de Penthièvre. After about 3 km, you’ll reach a star-shaped junction on a right-hand bend.

(2) Carry on straight ahead along Rue des Rochettes. Pass the supermarket on your right and, at the junction, continue straight on along the old narrow-gauge railway line (cycle path; closed to all motorised vehicles). Follow it to the end (entrance to Matignon).

(3) At the roundabout, enter the shopping centre car park, cross it and exit onto the D786. Follow it to the left for 500 metres, then turn right (towards the recycling centre and the industrial estate).

(4) At the junction, on the corner by the recycling centre, turn left (following the ‘Voie Europe 4’ cycle route signs). Cross a T-junction with a traffic island, then cross the Pont Quinteux stream. At the next ‘Stop’ sign, continue straight ahead and cross Rue de la Croix Chauvel to follow Rue de la Halte and join Rue du Guébriant (D19).

(5) Carry on straight ahead towards the nurseries on Rue Harrel de la Noë. At the next junction (no entry, except for residents), carry on straight ahead until you reach the D786.

(6) Cross the René Pléven Bridge and head towards the Guildo. Turn left onto Rue du Vieux Château and continue straight on until you reach Baie de Beaussais (D26).

(7) Turn left and follow this road until you reach a junction with a fishing boat on the left.

(8) Turn right onto Boulevard du Rougeret, then take Boulevard du Chevet to reach Pointe du Chevet.

(9) Return from the headland and take Chemin Saint-Christophe, the second right after the car park. After the cemetery, turn right onto Rue de l’Abbaye and follow it to the beachfront. Continue left onto Rue des Hass, then right onto Rue des Écluses. Carry on along Boulevard de la Banche and return to the junction with the fishing boat.

(8) Turn right onto the D62, Boulevard des Dunes, and continue until you reach a roundabout.

(10) Carry on straight ahead and, a few metres further on, turn right onto Boulevard du Vieux Château (a dead-end road). Pass Rue du Vieux Château and reach a three-way junction about a hundred metres further on.

(11) Turn left onto Chemin du Petit Train, rejoin Rue du Vieux Château (which you took on the way there) and follow the road back to the junction after the René Pléven Bridge.

(6) Continue along the D786. At the left-hand bend, turn right onto Rue du Val towards Château du Val. Follow this road, ignoring the turnings to the right and left, until you reach Quatre Vaux Beach.

(12) Carry on along the road; at the next junction, turn right to reach a four-way junction with a chapel on your left.

(13) Turn right onto Rue Sainte-Brigitte, leave the hamlet and, just past the next few houses, turn left towards the water tower. Near the water tower, turn right towards Saint-Cast and join the D19.

(14) Follow it to the right, passing Pen Guen Beach on your right, and continue to the next roundabout.

(15) Turn right onto Boulevard de la Garde, heading towards Pointe de la Garde, and continue to the Oratory of Notre-Dame de la Garde.

(16) Continue along the Grande Plage, the Boulevard de la Mer and the Rue de la Corniche.

(1) Turn right onto Rue du Port Jacquet and head for the small car park (S/E).

A lovely little walk that will take you through some beautiful spots.
That said, a few notes and alternative routes:

  1. You can avoid Matignon ((3)) by following a cycle route (might as well make the most of it). After the point (2), don’t carry on straight ahead as you leave the village, but first turn right then left to go past the riding centre. It’s a cycle path through the forest, so it’s very pleasant. You’ll rejoin the ‘official’ route after the hospital, towards Clos Girard
  2. Between (9) and (10) In Saint Jacut, at ‘La Blanche’, you can follow the coastline without going through the village and therefore without rejoining the outbound route (thus avoiding the point (8)).
  3. At point (11) on the return leg of the circular route, you can take the road branching off to the right. However, please note that this joins the GR at the Château du Guildo, where you must dismount from your bike. But you’ll be rewarded with a magnificent view of the château.
  4. At point (16), the route also crosses the GR; you must dismount from your bike for safety reasons (the descent is steep) and out of respect for walkers.

Please do feel free to let us know if you’ve completed a route that was circular but you feel it’s incomplete.

I found the outward journey enjoyable, although it was a bit too fast-paced for my liking when it comes to mountain biking.
On the other hand, the return journey is all on the road and the signposting isn’t precise enough.

So is the average rating based on how difficult it is?

A hike we did as a couple.
The description said it was suitable for families, but in our opinion it’s too difficult to do with children or teenagers.
We came across a 15 per cent gradient which we had to cycle up and down – you’ll need good brakes.
We completed the circular ride in 4 hours.
Otherwise, the scenery is magnificent, and the roads are quiet and pleasant.
A ride worth doing, but not with children.

I went for a walk along one of the trails around Châteaubourg – it was really nice, and what’s more, everything is signposted, so it’s absolutely lovely.
