From Tréambert to Sorloc via the marshes and coastline

Between Mesquer and Quimiac, the marsh cuts deep between two rocky mounds. The slopes here form a grid-like pattern in which the old shellfish beds are set, and, further back, salt pans that are still in use.
This bird paradise has benefited from extensive restoration work, the results of which are maintained by sheep as they graze on the vegetation.
A stroll through the streets of Quimiac takes you to the coast, opening up the view onto the Bay of Vilaine.

Description of the walk

The walk starts at the side of the D452, as you approach the marshes, downstream from the Tréambert holiday village.

(S/E) Cross the salt marshes, following the edge of the road. The road is very busy, but a central reservation separates the traffic from the footpath.

(1) At the end of this safety barrier, take the path branching off to the right. For over a kilometre, it winds its way through woods and marshes: to the left, a dense oak forest; to the right, salt pans where numerous birds frolic and, occasionally, a few salt workers are at work.

(2) Pass the path on your right which runs along a bank between the ‘étier’ (the watercourse that feeds the salt marshes according to the tide) and a salt pan. Continue to the left for about a hundred metres, skirting the woodland, before coming out onto a housing estate road (Impasse Saint-Pierre). Follow it until you reach a crossroad. Continue along the small Rue des la Rangée directly opposite, then turn right to reach the Place du Marché. Cross the square diagonally to reach the Tourist Office.

(3) Turn left onto Avenue de la Plage, which leads to the beach.
Once you reach the beautiful Lanséria Beach, follow the coastal path that runs between the boundaries of the plots and the top of the beach. Just before reaching Pointe de Beaulieu, turn right onto a lane that takes you back onto Boulevard de l’Océan. Turn left twice to rejoin the coast and walk round Pointe de Beaulieu. The path then heads back towards Rue du Fort and passes by an old mill.

(4) Turn left to return to the coast. Reach Pointe du Toul Ru by following the small road that leads there.

(5) As you pass this headland, a landscape bathed in red unfolds before your eyes. This well-sheltered cove owes its name to the red cliffs that surround it.
At the end of the harbour’s embankment, head right along the path built at the foot of the cliff. The boats moored against the rock form a multicoloured garland just above this footpath.
At low tide, continue along the beach to the far end of Baie du Carbonnais. Climb back up onto the cliff via the slipway at the end of the beach, and follow the coastal path until you have passed Pointe de Sorloc.

(6) Once you reach Sorloc Point, head back down onto the foreshore to reach the access path to the beach in front of Le Petit Caboullot (beach bar).
At high tide, all you need to do is make your way from Toul Ru to Sorloc by following the streets behind the beach and the D352. This is far less charming, which is why it’s worth checking the tide times before setting off.
In Sorloc, cross the departmental road opposite the main beach access and follow the road to the left until you reach the marshes.

(7) Just as you reach the first ponds, take the path branching off to the right, running alongside the marsh. It winds its way initially below the houses, then moves away from them as it heads deeper into the marsh.
After crossing a footbridge, the path goes round a final pond before joining a track suitable for vehicles. Turn left and head towards the road that crosses the marsh. Turn left again when you reach it.

(8) After crossing the wetland, turn right onto the track towards La Saline au Duc. Leave this track when it turns left, and follow the path that runs along the edge of the marsh. On the left, a few fine properties precede the Tréambert estate and its holiday village.
Once you have passed the last camping pitches at the holiday village, the path rejoins the D452 and the starting point (S/E).

Notes

Between (7) and (8) Here, there are no salt marshes, but rather former oyster beds. Major restoration work has been carried out here in recent years, particularly to eradicate baccharis, an invasive shrub that was taking over the whole area. Sheep are now responsible for keeping the site free of this plant. Please respect the fences running alongside the path.

Between (8) and (S/E) On the right, the first active salt pans reveal their intricate water channels. In the centre are the ‘œillets’ – basins where the salt will be harvested once the evaporation process is complete.

To make the most of the seaside, you should set out on this route when the tide level allows you to walk along the coast. Unless you plan to walk along the streets and roads through Quimiac, it is best to check the tide times before setting off on this walk.
Tide times for Mesquer

Refreshments available in Quimiac and Mesquer.

Alternative route: At Sorloc, you can extend the route by heading up to Pointe Merquel. To do this, walk along the beach and continue along the coastal path. Once you reach the Merquel jetty, return via the other side of the headland, pass by the foot of the small white chapel and walk along the beach to the Baule de Merquel car park. Then cross this car park to return to (6) and resume the route described.

Worth a visit

Right next to the car park at the start of the route, there is a salt marsh that is open to visitors. Opening hours vary depending on the season and weather conditions.

A few hundred metres from the centre of Quimiac stands the Saint-Louis Chapel. This modern building offers a particularly peaceful atmosphere when the light filters through its stained-glass windows.

A lovely little walk; thanks to the low tide, we were able to walk most of the way along the beach, which was very quiet at the end of April! Thanks to the author.

A beautiful hike, best done at low tide, which allowed us to follow the beach.
An easy walk with a very good description.

A very pleasant walk. Our only regret was that high tide prevented us from following the beach along the coast.
Thank you for introducing us to a very pretty walk that is very easy to access and has beautiful shaded sections.

A very pleasant walk with alternating countryside and coastal scenery.
A quick note about the confusing directions at the start: it would be much simpler to specify that you should take the D52, Route de Kerlagadec, towards Kerrallement. Follow the signs for the "Le château du petit bois" campsite, which will take you past the starting point car park on your left.

A very beautiful hike with our family of three children, the youngest of whom is five years old. It took us three and a half hours, including a picnic break. There were many muddy sections in the marshes in December, but we had a great time and enjoyed the sunshine.
Thank you.

Be mindful of the tide times, otherwise it's a lovely compromise between the seaside and the marshes!

I went on this short hike with a group of 20 fellow walkers.
We took advantage of the low tide to walk along the beach.
We returned via the marshes.
We enjoyed the variety of landscapes.
Thank you for this route.
