The lower Jura mountains between Sergy and Crozet

Hiking on the lower Jura mountains, on wide paths through fields and forests, connecting the heart of two villages in the Pays de Gex, partly following an ancient Roman road. Throughout the hike, you will see old buildings (Gex farms, castle, churches), views of the Pays de Gex plain, and further afield, the Salève, the Alps and Mont Blanc in particular.
This route can also be done by mountain bike.

Description of the walk

Large car park next to the "La Calame" village hall, located behind the cemetery and opposite the primary school.

(S/E) Opposite the school, turn left onto Rue des Prêles. After the first bend, turn left onto Chemin de la Charrière and join the D89A, Rue du Crêt de la Neige (restaurant on your right). Cross over, turn left and climb up to Sergy Castle.

(1) Turn right onto Chemin des Granges, which is paved at first, then gravel (passable by vehicle). Cross the bridge over the Fion stream and pass a water collection station.

(2) Take the path on the left which climbs straight up towards the Jura mountain range. Cross the D89 and continue climbing straight ahead. You will soon leave the cultivated fields behind and enter a strip of trees separating the large meadows from the lower mountain. Go straight ahead at the fork and shortly afterwards you will reach Chemin de l'Etraz, marked by wooden posts and yellow arrows.

(3) Turn right towards Crozet onto the path, which becomes a tarmac road. After passing the first houses, leave the road that descends and take a wide stony path on the left that passes above the hamlet of Villeneuve. Continue straight ahead until you reach a tarmac road.

(4) At the first crossroads, turn left onto the road that climbs steeply straight towards the Jura mountain range. Keep to the right at the junction. The road quickly becomes a stony track again and climbs through the forest.

(5) As you approach the houses, turn right at the fork. Join the Route de la Télécabine and descend to the right.

(6) At the four-way intersection, turn right onto Rue du Jura (no vehicle access). Walk past the cemetery and Crozet church (on your left), the old houses in the village and finally the town hall (on your right), before coming out onto the D89 (Rue de la Mairie). Turn right, then cross the road using the pedestrian crossing near the school car park.

(7) Cross the car park diagonally to take Chemin des Croux, a tarmac road that slopes slightly downwards. At an isolated house, turn right and continue along Chemin des Croux.

(8) At the first crossroads, turn right onto Chemin des Curtils, which runs alongside the fence of the Jiva Hill golf course (on your left). Cross a main road and continue straight ahead. At the crossroads on a small hill, continue straight ahead, then, in the left-hand bend, leave the tarmac road and continue straight ahead on the stony path.

(9) At the first crossroads, at the edge of the forest, turn left onto Chemin de la Paillaz. When you reach the main road at the entrance to Sergy, take the pavement on the right.

(10) At the church, continue straight ahead, taking the pavement which changes sides of the road at the town hall. Continue to the entrance of the Peupliers housing estate, turn right to return to the car park and the starting point (S/E).

Worth a visit

Sergy Castle
Private castle dating from the 13th century and remodelled after the Revolution. It comprises a main building flanked by two towers, one with spiral staircases and the other with 19th-century balconies, as well as outbuildings and a large park.

Chemin de l'Etraz
An ancient road at the foot of the Jura mountain range that existed in Roman times. It runs above the villages and was marked by the Pays de Gex Tourist Office (wooden posts and yellow arrows), but unfortunately many of the markers have disappeared.
It seems that the Chemin de l'Etraz follows an older route, corresponding to the path taken by the Helvetii during their flight.

Crozet Church
This is a modest building: a simple nave with a semi-circular vault and two side aisles. It was completely rebuilt in 1827. Worth seeing: the traditional organ built for the church.

Sergy Church
In 1779, Pierre Pictet became Lord of Sergy until the Revolution. The most significant event of the period was the construction of the Church of Saint-Nicolas, which can still be seen today.

Other things to do nearby:
Crozet cable car (skiing in winter, mountain biking in summer).
Depending on the season: wild garlic and mushroom picking.
Geocaching: 9 caches along the way or in the immediate vicinity.
Jiva Hill: golf and horse riding.

Between points 3 and 4, it was impossible to follow either the description or the GPS. I found the GPS track very easily by taking the main path and then a small trail that climbs steeply to the left.
A magnificent walk, alternating between woodland and open countryside, with spectacular scenery. Thank you very much for this description.

Interesting hike on the way there, very beautiful trails, but more monotonous on the way back with some tarmac. Please note that the car park in front of the Crozet school is closed for renovation work at the moment.

For me, there is a lot of tarmac on the route. But it was a pleasant walk on a cold day.

A lovely walk through a beautiful forest with occasional views of the Jura and the Alps. Recommended when it is very hot as 80% of the route is in the shade.
