The Marais des Chassettes

A walk around La Ravoire and Challes-les-Eaux in the Chambéry metropolitan area, passing through the Marais des Chassettes. This is a protected natural site that is home to several species of local flora and fauna. Here you’ll find the biome that once existed here: the marshes of the Alpine valley floors. It’s also an opportunity to explore the Challes-les-Eaux leisure centre, as well as the hill where the church stands and the new quarter of La Ravoire.

Description of the walk

Set off from the free “Le Silo” car park in the centre of La Ravoire.

(S/E) Head south, passing the municipal rugby pitch and the village cemetery. Turn left onto Rue de la Concorde and walk past the entrance to the old cemetery. Carry on straight ahead, then turn right to walk past the new cemetery. Continue straight on past the homes of the Domaine du Parc, then, almost at the end of Rue des Puits d’Ordet, you’ll reach the cycle path that runs between the meadows.

(1) Turn left and carry on straight ahead along the cycle path beside the Mère stream for a good kilometre until you reach the road on the other side. This is the N6 (Italy – Savoie – Rhône). At the roundabout at the entrance to Challes-les-Eaux, cross the road carefully to reach the opposite side, then head for Chambéry Aerodrome.

(2) Once you reach the car park for the aerodrome and the leisure centre, turn right onto the cycle path (Voie Verte des Planeurs), then right again to enter the Challes-les-Eaux leisure centre. Go round the pretty pond, pass the open-air café and head towards the tennis courts. Follow the sports grounds until you reach the car park at one of the entrances.

(3) Return to the N6, then cross it – taking care at all times – to reach the houses opposite. Turn back for about a hundred metres, then head up to the left through the trees along the winding footpath provided for this purpose. At the houses, turn right, then right again at the next junction. In the Chassettes residential area, turn left onto the footpath, then left again until you reach the woods.

(4) Follow the signposted footpath that runs the length of the woodland heading south. On this path, after passing a good dozen houses, you will reach the ‘official’ entrance to the marsh.

(5) Enter the marsh via the main path. Carry on straight ahead through the woodland, following the information boards (three or four, I believe). Keep going straight ahead. After about ten minutes, you’ll come to a junction: do not turn left or right, but carry on straight ahead. After a while, you’ll emerge from the woodland. Carry on straight ahead towards the houses. Follow the path that runs alongside all the houses on your left. After passing about fifteen detached houses, you’ll reach the tarmac road again, near Rue des Puits d’Ordets, where we had taken the cycle path.

(6) Do not take this road but turn immediately left towards the housing estate via Allée de Chassettes. At the far end of the estate, on the right, there is a flight of steps leading up to Champ Clavier: take these (they are not very visible from the entrance to the square, so walk a little further in). Once you reach Rue Richelieu and the green park, head uphill towards the church. Take the service access road through Champ Clavier Park, then take the small flight of steps next to the local youth centre. You will arrive at the forecourt of Saint-Étienne Church.

(7) Visit the church grounds, then turn left, walking alongside the parish hall and the church. Take the path behind the church which leads back to the road. Then walk down Rue de l’Église until you reach the new Valmar neighbourhood on your right at the junction with Rue de la Concorde. Head towards the Valmar neighbourhood, cross the road, then walk through the neighbourhood until you reach the central square in front of the Town Hall. Then continue eastwards along the Promenade Villard Valmar, between the new blocks of flats, until you reach the small square and then the car park where you started (S/E).

Notes

This walk partly follows the ‘Circular Walk of the Marais des Chassettes’ route, which is recommended by the Chambéry Urban Community, various walking blogs and the Savoie department’s website.

This walk takes place in both the municipalities of La Ravoire and Challes-les-Eaux.

There are several possible starting points (the Challes-les-Eaux leisure centre, the car park near the new Domaine du Parc in La Ravoire, Chemin des Teppes, etc.). However, this guide starts from the new ‘Silo’ car park in the centre of La Ravoire, as it is free, close to amenities and completely secure. This also allows you to visit La Ravoire Church and the new Valmar town centre.

The Chassettes Marsh area is a strictly protected site. There are numerous information boards within the marsh explaining the local flora and fauna. It is an important breeding ground for amphibians, particularly common frogs. There are also several birds of prey (harriers, kites) and smaller birds (woodpeckers, nuthatches, etc.). You’ll also come across numerous peat bogs here and there (there was a time when the whole Chambéry valley consisted of marshes, hence the Marais de Boige, the Marais des Noux, the Marais des Crauses and others in the area).

The lovely Le Laurie’s brasserie in the centre of La Ravoire, just before you reach the starting point of the circular walk, is a great way to round off your walk.

Thank you to the author for creating this route. I shared it with a friend from Chambéry by taking her on this walk. The weather was lovely and we saw some beautiful sights, including the Bauges mountains and the gliders at the airfield. We had a picnic by the lake.

In the marshes, however, a section of the path was blocked by fallen trees. We had to turn back about twenty metres, then take a small track trodden by animals to get round the obstacle without any difficulty

Inside the marsh, the path is littered with fallen trees, but you can still get through...
A nice little walk.

I mainly followed the route on the GPS rather than the description. I found it a bit tricky to find my way through the woods. It’s worth noting that, as of 7 July 2024, part of the route is closed because of fallen trees, but this wasn’t clearly signposted, so I had to climb over a few trees to get through; there’s only a sign at the end of the route, just outside the woods. Otherwise, it’s a lovely little walk and easy to do.
