The Jacob-Bellecombette Waterfalls

On the outskirts of Chambéry, the Nant du Ruisseau du Pontet retains a wild course, hemmed in by urban development, with its waterfalls and gorges offering an interesting hike that continues up the Grobelle hillside for views over the Chambéry Basin. The return route naturally involves some sections along roads that are fairly unavoidable given the layout of the area.

Description of the walk

Start from Jacob-Bellecombette, Écoles car park (trail information board), reached from Chambéry via the Quartier du Biollay. Heading up towards Jacob church via the CD6, turn right into Rue du Corbelet, continue through the neighbourhood and turn right down Rue des Écoles.

(S/E) Walk down to the end of Rue des Écoles; at the bottom, turn left onto Route de Saint-Cassin, pass a roundabout and, just before a small bridge, turn left to reach the actual start of the Cascades trail, at a place called l’Eau Vive.

(1) Follow the right bank of the Ruisseau du Pontet, which meanders slightly. The slope becomes steeper as you approach the large waterfall. Turn right at Île aux Nymphes to reach its base, via the footbridge resting on two boulders (as of early 2025, the footbridge is closed due to damage).

(2) Retrace your steps and take the path uphill to the right. Further up, turn right again to reach the middle waterfall. Stop in front of it, but it is possible to climb over a few rocks to pass underneath the waterfall.

(3) Retrace your steps to the uphill path, take it to the right, with a few steps. The path runs parallel to the Route de la Cascade, which it joins just before the bridge over the stream: the upper waterfall is directly opposite.

(4) You can walk a little way up the left bank of the Ruisseau du Pontet to admire the potholes and the canyon. Retrace your steps and take the Route de Sécheron southwards, which leads up into the housing estate. Pass two dead-end roads on the left and continue up to the junction with the Chemin du Bois (private).

(5) Turn left onto the path running parallel to the track, which continues straight on and levels out. Pass a path leading uphill to the right and, shortly afterwards, take the path leading downhill to the left, which has wooden steps. It approaches the Ruisseau du Pontet, which it follows at the same level on the left bank, until it emerges from the forest just before an old ford.

(6) Turn back to climb up alongside a meadow, turn left to join a path coming from Tire-Poil and descend between the houses. Cross the bridge over the Ruisseau du Pontet and climb up the Chemin du Moulin opposite, turn right and reach the Croisement de Bellecombette on the CD 912 – Route des Entremonts.

(7) Cross carefully at the pedestrian crossings and head up the path opposite, which has steps, to the La Bergerie sign. Walk down a few metres to the right, then turn left onto a path that climbs through the forest to the Route de la Basinière. Turn right and cross directly south. At the next junction, turn left to climb to the junction with the La Basinière sign (altitude 480m – highest point of the route)

(8) Turn left to descend slowly through the forest, rejoin the Route de la Basinière and continue straight on to the Grobelle junction.

(9) Turn left and head down the road to the sign for La Bergerie. Head down to the right to the Route des Entremonts, which you cross with the same caution at the Bellecombette junction.

(7) Continue straight on along Route de Bellecombette, which climbs slightly. Shortly after the top, turn left to descend Chemin de Bellecombette. Further down, it rejoins the road, cutting across a bend, then passes between the road and Les Hauts de Jacob. At the end of a bend, turn right onto Rue de la Mairie, between the Town Hall and the Salle de la Jacobelle.

(10) Continue downhill to Rue de la Cascade, turn right onto it for 30 metres and turn left down Rue Jean-Baptiste Richard, which leads to the university campus. Leave it on the left to go down a path alongside the cemetery to the church.

(11) Walk down either the street or the steps to the start of Rue du Corbelet. Then walk down into the meadow to follow the footpaths, veering left onto the one that passes between the tennis courts and the schools, in front of which you will find the car park (S/E).

Notes

There are no difficulties if you stay on the path, which is marked in yellow from start to finish.
In wet weather, some sections may be slippery but remain passable.

Caution: the waterfall area is steep: there is a risk of falling if you stray from the paths.

Worth a visit

An amazing site: almost untouched wilderness in the heart of the urban area.

Like all waterfall sites, it is most interesting when the stream is flowing well.

The Grobelle area offers views of the Chambéry Basin, Lake Bourget and the surrounding Bauges and Jura mountains, after passing close to the industrial site of a cement works that operated for many years in Montagnole.

We did it on 18 March 2026; it was a very pleasant walk, with stunning vegetation and lots of flowers. We really enjoyed it.

We did this hike one afternoon after Christmas in the sunshine, which was great for working off all that food... The sign for the dead wood trail that tells you when to turn left is no longer there, but we found it anyway. The water was flowing nicely at the three waterfalls. It's true that you walk a lot on tarmac, but it did allow us to clean the mud off our shoes.

Hike completed in the time indicated, very enjoyable in good weather (risk of slipping in rainy conditions on the fairly steep climbs). Very busy.
Fortunately, there is a description as the route is not well signposted.

The first waterfall to see is the largest, but unfortunately the footbridge that offers the best view is out of order and access is limited. The route is very nice with beautiful panoramic views.

Hello, in some places, the signage leaves something to be desired. In fact, we met a lady who noticed the same thing.

This hike is a bit overrated. While the route along the riverbed is very interesting and well shaded, it only makes up a small part of the walk. The majority of the hike takes place in residential areas and on asphalt.

Very average hike, more than half of the walk is on the road in direct sunlight, waterfall with very little water.
Not recommended in the height of summer, perhaps better in spring or autumn
