The walk starts from the small car park opposite the little church in Jacob-Bellecombette.
(S/E) Walk up Rue du Presbytère and Rue du Cimetière, then continue along the path opposite and onto Rue de l’Église. Turn right, head towards the Town Hall, pass the school and its fountain, then continue along the pretty path that runs alongside Route de Bellecombette. At the next junction in front of the houses on Rue Anne de Chypre, head towards the houses.
(1) Turn left onto Rue Anne de Chypre, walking between the houses to the end, then take the path leading into the Bois de la Culaz. Continue along the path through the woods heading east until you reach the new Roches Blanches housing estate. Walk alongside the communal allotments, then continue along the small path that leads down to Rue du Granier. Follow it downhill to Route des Entremonts.
(2) When you reach the road as you leave the Casson neighbourhood, cross it and take the road opposite, the Chemin des Rendez-Vous. A few metres past the entrance to the Résidence du Bois Joli, take the small path on the right that leads uphill. This leads to the Parc de l’Étincelle and is signposted. Once near the park, continue along the main path indicated, which leads to the Maison des Charmettes. After about ten minutes through woods that rise and fall, you will reach the Chemin des Charmettes.
(3) Turn left onto this road and follow it to Jean-Jacques Rousseau’s house, passing the tight bend for cars in the shade.
(4) After exploring this remarkable site, retrace your steps for a few minutes.
(3) Before the bend, take the small path on the left leading to Buisson Rond Park. This path heads back into the woods. Follow Chemin des Rochères, then turn right towards the south at the main signposted junction. This is theGR® trail known as the Sentier des Hauts de Chanaz. Follow this path through woods and meadows to Les Hauts de Chanaz, at a place called Les Grandes Teppes, which is near the Fontaine du Diez.
(5) Once you have passed the Ranch des Gentianes and reached the few houses in the hamlet, take the road on the right at the main crossroads, then the path that follows on from it. You will then arrive at Maisolée, then Combe Boutet and finally Les Charolinières, until you return to Bellecombette. Everything is signposted on the yellow hiking signs; it’s pretty much straight on until you reach the houses and then the Route des Entremonts.
(6) Back on the Route des Entremonts, head back towards the houses on the Route de Bellecombette opposite. Then turn left twice between the farms on the Chemin du Moulin. Cross the Ruisseau du Pontet via the pretty little bridge, then take the path on the right which runs alongside the river. Keep going straight on along the entire Chemin de la Grobelle, which runs alongside the river. After a while, the path climbs slightly towards the meadows and eventually reaches the pretty houses of the Sècheron district. Pass between the houses along the designated path until you reach the road leading up to Montagnole and Saint-Cassin via Cesoler.
(7) Turn right towards Chambéry and the centre of Jacob until you reach the first waterfall of the Nant du Pontet by the roadside.
(8) Once you reach the waterfall, take the path on the left, known as Le Sentier des Cascades. Follow the path as it winds its way through the woods, past the river and the waterfalls. Continue downwards without turning right onto the paths leading to the Corbelet buildings or the Eau Vive houses. Carry on straight through the woods until you reach the road to Saint-Cassin.
(9) Turn right onto the road, walk up through the neighbourhoods of central Jacob on either side of the Souris, keeping straight ahead past the Grand Pré Multi-Sport area. Once at Grand Pré, before reaching Chambéry, cross it via the informal path to return to the forecourt of the Church of Jacob-Bellecombette (S/E).
