Description of the walk

The triangular crossroads at the entrance to La Baudrière is the starting point for groups arriving by bus. Individuals arriving by car can go directly to the car park on the left-hand side of the road before the bridge near the (1).

(S/E) Take the Chateaulong road and descend towards Lac du Jaunay.

(1) Before the bridge, turn left onto the path leading to the car park. Shortly afterwards, take the path on the left and immediately after that, ignore the path on the right which descends to the lake (dead end). The path follows the southern shore of the lake. Further on, it runs along the edge of a forest and overlooks the lake slightly.
Near a point of land, take the path straight ahead, leaving the one that branches off to the left and goes around a cove below Roche Guillaume. Cross the bridge, which avoids having to walk along both banks of the cove in question.

(2) At the end of the bridge, take the path on the right. This path follows the shores of the lake and emerges a little further on from the wooded area. It then goes around a point of land, winds its way and passes below Roche Baudouin to rejoin the water's edge a little further on. A bridge allows you to cut across a small cove below the Servantière campsite.
After the bridge, the path winds through a wooded area and finally arrives at the end of a road coming from La Servantière.

(3) Follow the road for a few metres and immediately turn right onto the path that runs alongside the lake to reach the Lac du Jaunay dam next to the drinking water plant near La Savarière.

(4) Cross the dam and take the path that follows the northern shore of the lake, which is steeper in this section, to a place called Le Pré.
Once you are near the Bellevue campsite, ignore the first path on the left that leads to the campsite and, a little further on, the path on the right that descends to the lake and runs along the shore. Continue along the hillside towards Le Pré.
Continue straight ahead at the next junction and join a slightly larger path. Turn right towards Le Pré, which is only a few hundred metres away. Once you reach the road, turn right and cross Le Pré to come out at a T-junction.

(5) Continue right towards the lake shore. Shortly after a building on the left side of the road, the road gives way to a path that runs along the north shore. Continue straight ahead, staying as close as possible to the lake, until you reach the Chateaulong road at La Baudrière.

(6) Cross the road and take the path opposite. At the entrance to the bridge over Lac du Jaunay towards La Baudrière, leave the path on your left that goes all the way around the lake (see practical information) and take the bridge.

(1) At the end of the bridge, individual walkers will find themselves back at the car park they started from. Walkers in groups and those travelling by bus should walk back up the road to the triangular crossroads, which marks the end of the route for groups (S/E).

Notes

The starting point for this route is located at the crossroads at the entrance to La Baudrière, where groups can be dropped off by bus.
For individuals, there is a car park on the left just before the bridge near the (1) (right bank of Lac du Jaunay) and another, a little after the bridge, on the left bank of the lake (200 metres after the bridge, just after the bend in the road).

This hike requires sturdy footwear, especially for the section between point (4) and point (5), which is steeper. Some sections of this hike are quite steep, either uphill or downhill, and can be slippery due to the presence of stones.

It is possible to walk all the way around Lac de Jaunay by continuing along the same shore after Chateaulong and crossing the Jaunay via the upstream dam located below the Moulin des Rochelles. This route is just over 13km long.

Lac du Jaunay is a drinking water reserve: swimming and motorboats are prohibited.
The flora and fauna are a delight for nature lovers. The observation footbridge at Moulin des Rochelles, in Chapelle Hermier, is a strategic spot for observing wildlife.

Lac du Jaunay is a popular stopping place for certain species of birds. It is also home to some very photogenic animals: green tree frogs, grey herons, kingfishers, mallards, otters, genets and tawny owls.
Educational panels explain the lake life of many diurnal and nocturnal species.

Worth a visit

Le Jaunay
Le Jaunay (originally La Jaunaye) is a river in the Vendée department and a tributary of the coastal river La Vie.
The length of its watercourse is 45.4 km.

Le Jaunay rises in the commune of Venansault at an altitude of 50 metres. It then crosses or forms the boundary of the various communes it encounters on its way to the sea: Landeronde, Beaulieu-sous-la-Roche, Aizenay, Martinet, La Chapelle-Hermier, Saint-Julien-des-Landes, Landevieille, L'Aiguillon-sur-Vie, La Chaize-Giraud, Bretignolles-sur-Mer, Givrand, and joins the Vie at Saint-Gilles-Croix-de-Vie at an altitude of 6 metres.

Its final course has not always been the one we know today. Two or three centuries ago, the Jaunay was a small river that flowed directly into the Atlantic, along its land course, towards the part of the coast known as "Roche-Biron", north of Bretignolles-sur-Mer.

A storm filled its mouth with a new dune, flooding the hinterland and thus changing its course through the marshes behind the dune cordon, until it reached the Vie, into which it now flows, in the port of Saint-Gilles-Croix-de-Vie.

Lac du Jaunay
Lac du Jaunay is a 3,700,000 m3 drinking water reservoir covering 114 hectares and stretching over 8 km. It was created by the construction of a 200-metre-long dam at La Savarière, in the commune of Landevieille.

This lake is very popular for fishing, which is open all year round, except for pike and zander (closed from the last Sunday in January to the second Saturday in May).

Left bank of the Jaunay: Bretignolles-sur-Mer, La Chaize-Giraud, Landevieille.
Right bank of the Jaunay: L'Aiguillon-sur-Vie, Givrand.
Both banks of the Gué-Gorand: Coëx, Saint-Révérend.

A pleasant walk on a sunny day. The start is very easy with flat terrain, but after crossing the lake, the path becomes hilly with steep ascents and descents, some of which are via large, uneven steps. The second part is not suitable for pushchairs. Walking sticks are recommended for some people.
It's a shame that swimming isn't allowed in the lake.

A very pleasant walk with beautiful views. Not very busy. It was chestnut and mushroom season, so there were quite a few gatherers but few hikers. However, you do need to be well-shod and fit, as it is physically demanding in places, difficult to access and muddy. I arrived via La Chapelle Hermier, so I parked in one of the car parks after Câlins Ca-ânes, and the trail is well signposted.

The course is divided into two sections, one for walking and the other a little more challenging.
Very pleasant in good weather as there is plenty of shade along the route.

A bit tricky to find the start of the hike.
Not recommended if it has rained heavily in the previous days as it is very muddy, especially on the first part of the route.

A very beautiful hike, though a little difficult on the way back with my wife having a muscle problem that day. There were a fair number of people out, but it was a public holiday, the weather was fine, and the regulars were out (walking their dogs and riding a bicycle that thought it was all alone).
There was some uncertainty at the start about which path to take on the left. We followed the wide path that climbed up to the left and found what I think was the normal path a little further on, with no consequences other than a beautiful view at the top.

Hello,
Very interesting hike around the lake.
The problem is identifying the car park for the starting point, as there are three car parks very close
before and after the road bridge at La Baudrière.
We weren't in the right car park and set off in the wrong direction.
No matter. It will be an opportunity to do it again.
Well done for your work.

A very beautiful hike around this lovely lake, which offers a change from the ocean environment without straying too far from the sea (about 30 minutes).
Thank you for discovering and sharing this with us

A very beautiful walk around the lake, a bit steep in places but nothing too challenging. Halfway along the route there is a small bench with a view of the lake...magnificent.

Hello,

Thank you for this information, which does not affect the hike as there is a path that goes around the cove.

A lovely, peaceful walk.
The bridge that cuts across a small cove below the Servantière campsite is no longer passable.
