Description of the walk

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).

Worth a visit

(S/E) The main activity in the Port of Carro is fishing. Mussel farming and sea urchin fishing contribute to making this small port a veritable seafood market.

The Pointe de Carro quarry dates back to Roman times and is reminiscent of the blocks used to build the Pont du Gard. On the Carro plain, in Les Arnettes, the semaphore tower dates from 1808.

The Soubrats quarry may be a westward extension of the Arqueirons quarry, but it was exploited later. A north-south rutted track crosses this quarry. Mainly exploited from 1664 to 1686 and covering an area of 170,000 m², the site contains traces of in situ dwellings: drystone shelters, stone huts and galleries.

Saint-Jean-Baptiste Church was built in 1859. The bell tower bears the signature of the master stonemasons. The bell tower was built with stones from La Couronne in 1666. Each cornerstone of the bell tower was donated by a stonemason who engraved his mark on it. Inside the church, stonemason's tools are on display.

German blockhouse dating from the Second World War.

The potential of the quarry has been known since the 5th century BC due to the presence of the Gallic village of L'Arquet just above it. It was the first stone quarry opened in La Couronne by the Massaliotes during the Hellenistic period. It was used as a shipping port in the 18th century.

(10) The quarry is currently preserved over an area of 1,200 m². The sea penetrates very deeply into the quarry and sometimes covers it up to the quarry face. The current lighthouse was erected in 1960. From its height of 30 m, it projects a red beam of light to signal its position.

(12) Since ancient times, coastal quarries have been extensively exploited to build the main monuments of the Phocaean city. The Baou Tailla quarry, clearly established above sea level, is one of the best-preserved coastal quarries. It is characterised by three large extraction units, separated from each other by vertical quarry faces.

A lovely, varied walk with plenty to see, combining wartime ruins at the start with quarries in the second half.
A few tricky bits on the trail, but we managed to get back on track eventually, so no complaints – a lovely afternoon, and sunny too!

Thanks

Very beautiful trail, but quite a few obstacles at the start due to overgrown vegetation.
Superb route through unusual and spectacular quarries.

Hello Manon Denis, thank you for leaving a review about this hike. To our knowledge, this is the only trail with this name starting from Carro and officially marked as part of the "Le grand sentier de la Côte Bleue" project. However, it is true that several routes may overlap at times, as the trails already exist.
We hope you enjoyed the scenery along this route
Have a lovely day.

To the editor: The start of the route is unclear; the municipality of Carry has marked out a route with the same name in blue. The route does not always follow this route, which is a source of uncertainty, especially as this route sometimes crosses through thorny bushes. Fortunately, the route is well cleared, otherwise you would have to go back and forth.
Why make it so complicated? From the railway, the route is fine and merges with the blue one, phew!
The first part is uninteresting; only the detour around the peninsula is worthwhile.
I would recommend the route marked by the tourist office instead.
Another point: the PDF route gives coordinates in degrees rather than UTM-UPS:
not usable with top25! (I have already pointed this out, but Visorando has not yet understood my comment).

A very pleasant coastal walk with a gentle climb inland, except for the ascent from CARRO. Soon, the refinery chimneys will disappear, giving this site, steeped in history from the Gauls to the present day, a more authentic feel.

We had a great day on a very pleasant route. We were lucky to have beautiful sunny weather and the sea was magnificent. It was a bit windy at the start of the hike, but it quickly calmed down and we were able to have a picnic by the water. MAGNIFICENT!

Very, very good along the coastline and through some wooded areas. Disappointing for the rest. The route on the map is somewhat spoiled by poorly placed markers, which cause errors. The blue route is "fantastical" in some parts. Avoid the detour to the Auffans quarry, as there are dogs and a frightening man. Not very busy inland, much busier on the coast. Thanks anyway. Variation towards Sainte-Croix chapel to be done.

Hello,

Apart from rock enthusiasts, this hike is not particularly interesting. Only the coastal path section is enjoyable.
It should be noted that the blue markings are illogical, and of course, we got lost two or three times.

Thanks anyway...

With our club, we did the route starting from the Couronne lighthouse and pushed on to the chapel above Sainte Croix beach, which is well worth a visit.
The inland part of the coast, which crosses the village and numerous roads, is not particularly interesting, to say the least...
The blue route is very poorly marked, a bit haphazard.
Fortunately, there is the seaside with the Ponteau chimneys behind you...
All in all, I would recommend doing a round trip along the coast from Tamaris beach to the beach before the Ponteau chimneys.
