Note: much of this walk follows a route marked by wooden signs bearing a green dot.
Start: Salle des Fêtes car park.
(S/E) Head off to the right: Rue de la Mairie; in the village, at the junction, turn left then immediately right.
(1) After the cemetery, at the bend, take the path on the left. It descends to the hamlet of Camarel. On the road, turn left. Follow this road to the bottom of a hill and take a path on the right.
When the path veers sharply to the right, about twenty metres further on, in a field, there is a beautiful menhir. Continue along this path.
(2) Turn left to head down towards the stream Le Théoulas. Continue to reach the road and the hamlet of Camarel. Return to the road by turning left.
At the end of this road, turn left onto Rue Bellevue.
(3) Carry straight on at the junction with Rue Croaz Naval towards Locmaria. At the next junction, turn right.
(4) At a left-hand bend, take the path that continues from the road. Follow this path alongside a field to reach the Théoulas stream below. The path climbs through a wooded area, winding its way up in a series of small bends. It ends at the Kervéziou road.
(5) Turn left onto it to reach a wayside cross. Cross the road and take the path that continues from it. When you reach a new road, turn right onto it and continue through the hamlet of Kerbiquet.
(6) As you pass, admire the small chapel on your right. Join the D20 and follow it to the left. Take the first road on the right, then follow a right-hand bend.
(7) Take the path on the left, then after 80m, continue onto another path on the right. It continues through the forest, running more or less parallel to the Jaudy. Near the D15, it branches off to the right, followed by an uphill section, a U-turn and then a descent. After a few slightly tricky sections, continue along the path that runs alongside the D15 below.
(8) Cross the D15 and continue along the path which rejoins the Jaudy.
(9) The path leads onto a road; take it on the left and continue along it.
(10) At a crossroads, take the path signposted for the hotel and the restaurant "Aux délices de Margot".
Follow this path and, before entering the castle courtyard, turn right towards the car park. Following this route, go through the entrance opposite the castle then turn right.
At the "Sacré-Coeur" statue, follow the path to the left towards the oppidum.
(11) Walk around the upper part of the oppidum to enjoy a 360° view of the landscape, then at the bottom of the descent take the path on the right which circles the first line of defence of the oppidum (the ditches are over five metres deep in some places).
Leave the oppidum via the arrival path. Turn right at the statue and cross the castle courtyard to reach the road.
(10) Turn left. Walk past the underground sewage treatment plant on your left and enter Brélidy via Rue de Kergouriou.
(12) In the village centre, take Place du Bourg to walk past the church and cemetery on your left. Head south along Rue Bellevue to the crossroads.
(3) Turn right, then after 50m take the path on the right to return to the car park at the start (S/E)
