Departure from the Saint-Blaise car park.
(S/E) With your back to the road, take the path that climbs to the left, following the sign for Boucle de la forêt de Castillon, marked in yellow and yellow/red.
The path leads to the Saint-Blaise archaeological site on the right, then to the Saint-Blaise chapel on the left. Go through the gate and follow the track that goes around the site on the left.
(1) At the first crossroads, turn left, following the yellow markings and the Castillon Forest Loop. 400 metres further on, at a T-junction, continue left and follow the wide path.
Leave the first path on the left (not marked on the map) and take the next one on the left.
(2) When the yellow/red markings turn right, continue straight ahead. The path curves into an S shape and turns left 300 metres further on onto a trail. Turn right twice to rejoin the path you left earlier.
(3) Continue left for almost 400m, then at the crossroads, turn left, go 50m and turn left again. Leave the next path on the right, join a track coming from the left further on and continue straight ahead. Enjoy the views of the Étang du Pourra.
(4) When you reach a crossroads on an esplanade, ignore the two paths on the right and turn left. Once on Chemin de Castillon, turn left and follow the equestrian centre.
(5) At the end of this road, turn right and cross the car park. Go through the gate and continue along the track that descends to another gate.
(6) Leave the signposts on your left and take the path on the right. From here, there are no more signposts, but continue along the path that runs alongside the Martigues canal. Admire the Étang d'Engrenier and Étang de Lavalduc along the way.
After 2 kilometres along the canal, a path climbs up to the right towards the car park where you started (S/E).
