Park in the Ragues car park at the small fishing port of Carro.
(S/E) Facing the port, turn right onto Quai Vérandy.
Pass in front of the Croix de Carro, built in tribute to sailors lost at sea. Then follow the coastline to the Voie Verte car park, enter the car park and take the blue marked trail.
(1) At the three-way junction, turn right and cross the burnt area (fire of 26 July 2017). Go straight ahead at the next crossroads to reach the old water treatment plant.
Turn right onto the Bonnieu DFCI track. When you reach a triangular grassy crossroads, turn left, heading north. After about 200 metres, take the small path on the right, lined in places with rutted tracks, then turn right again to reach the Arnettes quarry.
(2) Turn back, turn right for about 30 metres, then left to rejoin the path you left earlier. Follow this path to the right to quickly reach the old semaphore opposite the crossroads.
(3) Return to the crossroads and continue left on the path marked in blue towards the railway line. Before you reach it, turn right onto the path and then take the second path on the left. This path makes a U-turn to run alongside the railway line, allowing you to see the faces of the old Soubrats quarries and the drystone shelters. The Arqueirons quarry is located to the south-east.
(4) At this T-junction, turn left to cross the small bridge over the railway line towards Vallon de la Marrane. Follow the dead-end road to the right, then turn right again before the next "dead-end" sign and continue straight ahead to reach the Auffans quarry.
Then retrace your steps, turn left onto Chemin des Carrières and rejoin the D9e.
(5) Carefully cross the departmental road (no protected crossing) then climb up the Vallon de l'Eurré opposite until you reach the junction with the Route de Martigues.
(6) Turn right towards La Couronne, go around the roundabout on the right and continue along Rue Olivier Griscelli. Further on, on the left, you can admire the Church of Saint-Jean-Baptiste, built in 1859. Immediately after, keep left onto Chemin du Sémaphore.
(7) Turn left onto Chemin du Petit Mas, then follow Allée Bernard Nicolas on your left, upstream from the multi-purpose hall. Continue along the path, then, once at the top, turn right and cross the road to take the Voie Verte on the right, which runs alongside Chemin de la Batterie.
(8) Take Impasse de la Batterie on the left and you will arrive at a D.F.C.I. barrier. Take the path near the German blockhouse, then turn right and continue towards the Beaumaderie plateau. Head towards the sea, taking care not to get too close to the edge of the cliff due to the risk of rockfalls. Take the coastal path towards the 6th-century Gallic village of L'Arquet.
(9) Take the path on your right that runs along Arquet beach. Climb up to Pointe de l'Arquet, continue towards Couronne Vieille beach and walk along it.
(10) Turn left to discover the submerged quarry of Couronne-Vieille and its rutted tracks. Follow the path along Estanié beach towards the Couronne lighthouse, built in 1960. Cross the car park, head towards the cliff and walk along it, making a circular turn to the right.
(11) Take the steps on your left down to the ancient Verdon quarry. Continue towards Couronne beach. Walk along the dune and the esplanade.
(12) Take the stairs to Chemin de la Douane. Continue straight on towards Chemin de Baou Tailla, which runs alongside the ancient quarry of the same name. Continue towards Carro beach, then take the footpath on your left that runs alongside Esplanade Rabeton. Continue towards Quai du Vent Large, walk along the harbour to the Ragues car park (S/E).
