Assérac walks

This hike is located in Mesquer, in the hamlet of Rostu. The Bassin du Mès is an area where salt marshes have been created for centuries and were once highly developed. They are fed with seawater by channels leading from the "Merquel - Rostu - Pen-Bé" traicts, which are an enclave of the sea between the Pointe de Pen-Bé and the Pointe de Merquel. Oyster and mussel farming have also developed in this area. There are some beautiful views to be discovered.

The Mès, a small coastal river in the north of the Guérande peninsula, flows through a low, wide valley consisting mainly of marshes, draining the water into the ocean. The proposed route allows you to discover the upper part of these marshes and cross them via the Gras bridge, an ancient stone footbridge. This route should only be attempted when the water level in the marshes allows the paths surrounding them to be used.

The Pointe de Pen Bé juts out like a ship between Pont Mahé Bay and the Pen Bé and Rostu straits. While its maritime location is undeniable at high tide, it changes completely at low tide, as the sea then deserted the coastal areas. Whether at high or low tide, this is a route that is worth exploring at any time, as the landscape is so changeable.

To the west of the Brière Regional Nature Park, the Brière coast stretches from Pont Mahé beach to the Pen Bé strait. It offers a varied landscape of beaches, shorelines, wild coastlines, moors and salt marshes. A return trip connects to this route for a foray into Morbihan to Pointe du Bile.

Pénestin is just a stone's throw away from being an island. Although its ocean side faces the Atlantic, it is only connected to the hinterland by a strip of land wedged between two marshes. The suggested route takes you through the southern part of the area, formerly known as Larmor, between the Pont Mahé marshes and the cliffs of Lanchale and Le Bile.

Mesquer has a coastline opening onto the Bay of Vilaine and the open sea, but around Kercabellec, a small port between the village and Quimiac, there is a much more secret route between the marshes and the Merquel and Rostu tidal flats. Immerse yourself in this unique landscape where salt and shellfish farming are closely intertwined.

A lovely walk through the salt marshes and Mesquer Bay.

This route connects the three main areas of the municipality: Mesquer, Quimiac and Kercabellec. It allows you to discover the diversity of the area, first the marshes, then the countryside and the sea, which is particularly present around the Pointe de Mesquer.

The Château de Ranrouët is a medieval gem nestled on the edge of the marshes. Here, there is no fortified rock, but a slight elevation in the greenery. The marshes that surround it provided protection, and the proposed route winds through the surrounding countryside where land and water constantly mix.

Running along the left bank of the Vilaine, this path follows the riverbank closely, linking the two ports of Arzal and La Roche-Bernard, and offering a multitude of landscapes and views of the Basse-Vilaine. In summer, you can also return by boat or canoe.

One-third salt marsh, one-third countryside and one-third sea: a superb recipe for a salty cocktail!

This is a hike to undertake when other trails are impassable in winter.

The hike begins with three beaches and ends at Pointe de Merquel, which marks the entrance to the Bassin du Mès, famous for its salt marshes, mussels and oysters. The landscapes are magical, whether on the sea or marsh side.

Between Mesquer and Quimiac, the marsh sinks deep between two rocky hills. The embankments form a canvas in which the old shellfish beds are set and, further back, the salt marshes that are still in use. This bird paradise has undergone extensive restoration work, which the sheep help to maintain by grazing on the vegetation. A walk through the streets of Quimiac takes you to the coast, opening up the landscape to the Bay of Vilaine.

This hike allows you to discover the different faces of Brière: its marshes, its thatched cottages, its flora and fauna. Lots of paths, a few roads, all lined with oak trees, pines, gorse, willows and chestnut trees. Superb!

This hike starts at the car park of the Mine d’Or beach, along the coast north to Haut-Pénestin, to return by internal paths to reach the sea at Maresclé beach and then the starting point.

A country walk between Cosca, a stone's throw from the Arzal dam, and the Templar village of Lantiern.This walk along beautiful tree-lined paths and a few small roads connects the banks of the Vilaine estuary to the beautiful Saint-Jean-Baptiste Chapel, through pleasantly rolling countryside.The end of the route follows the botanical trail.The trail has been modified after the point (1), following the clear-cutting of the wooded area it used to cross, which made the trail disappear.

La Brière, France's second largest freshwater marsh, is a secret land hidden behind the surrounding hedgerows. The suggested route allows you to explore it from the land bordering it to the west and even catch a glimpse of it from the Sandun hill, which rises to a height of 28 metres. A real mountain in this flat country!But be careful, marshes are best explored when the water level allows it.Circuit temporarily closed

The Pointe du Halguen marks the southern limit of the Vilaine estuary. This promontory overlooking the ocean is also the northern end of the ochre cliffs that line the ocean front of Pénestin. A lovely walk is available around the village of Haut Pénestin, where long stretches of sandy beach precede secluded coves and abandoned salt marshes.

A very pretty route which starts in the countryside and forest and then follows the course of the Vilaine river. The start and finish are at the very pretty port of La Roche-Bernard.

An hour-and-a-half circuit with a few tricky sections. This pleasant walk alternates seamlessly between passages at water's edge and ridge-climbing, and also spans two bridges some 50 m above the Vilaine. The bridge circuit allows you to discover a small section of the river as it crosses the Sillon de Bretagne. Get your calves ready!

As you approach La Roche-Bernard, the Vilaine river winds its way through the geological folds of southern Armorica. The result is a rugged, wooded landscape that is very pleasant to walk through.
