Around the Abbey Lake
From the tourist office, go up Rue de Genève then Rue Delezay towards the West, cross the level crossing and reach Chemin des Buissonnets on the right.
Follow this then turn right onto the Salave road.
At the next intersection, leave Saint-Laurent en Grandvaux via the Route de l'Alouette on the left and reach the village of La Chamusse.
At the intersection with the Route de Saint-Pierre, turn left and go up the village to the hamlet Les Dadonins.
Carefully cross the D678 then continue on the same secondary road which runs through the village of Saint-Pierre.
Arriving at the hamlet Les Chauvins, turn right onto the D437, pass the horse-drawn carriages and take a small tarmac road below to the right as an alternative to the main road, to arrive at the hamlet Les Guillons.
Turn right again on the main road to cross the hamlet.
After passing the town hall, take a secondary tarmac road on the right towards the image silo which can be seen high up on the left.
At the intersection with the forest road, stay left until you reach the hamlet Les Bouviers.
Turn right, cross the hamlet and find the main road which you should quickly leave to go right and cross the hamlet Les Farrods.
At the exit of the hamlet, return to the D146 and approach the lake by the first tarmac road on the left. The route continues for a few dozen meters on a stabilized secondary road.
Find a paved road that runs along the edge of the lake to the lagoon. Take the road which goes up to the right to enjoy the view then go back down to the water pumping station.
Continue to follow the lake to pass the hotel-restaurant then reach the hamlet of Abbaye-en-Grandvaux.
Interpretation panels, a picnic area and bicycle racks are at your disposal to fully enjoy the site. Take the road again to leave the hamlet and turn directly right onto a secondary tarmac road indicating the direction of Mussillons. Continue straight ahead to the hamlet of Les Jeannez.
Go around the barn bridge covered with tavaillons (spruce planks traditionally used in Haut-Jura to protect facades exposed to bad weather) and go up to the top of the hamlet.
At the last house, take an unsealed secondary road on the right. Go past the quarry and the wash house then keep the left path at the next two intersections. The route leads to Saint-Laurent-en-Grandvaux through valleys and pastures.
Arriving near the first houses, head left towards the village center, cross the level crossing and go up Rue des Rochats to the stadium.
