La Charvaz - Ontex route

A medium-altitude hike in the Avant Pays Savoyard. Ideal for spring or autumn when there is still or already snow elsewhere.
The yellow markers and directional signs at the main intersections leave very little room for doubt.

Description of the walk

(S/E) From the car park at Billième Town Hall, cross the D44 road, start climbing and you will come to an intersection.

(1) Turn right, then cross Les Jacquins.

(2) At the end of the hamlet, turn right again. Continue along a good path that leads into the countryside. As you climb, leave a route to Gerbaz on your right and reach the La Teissonnière crossroads.

(3) Take the path on the right that enters the forest.

(4) At the next crossroads, ignore the path opposite leading to Col du Chat and continue left. This is a long climb, with some steeper sections.

(5) Leave the path and take a trail that climbs to the left to reach "Sous la Charvaz".

(6) Climb to the left and reach the summit in a few minutes.

(7) La Charvaz (1158m), close by, is another small summit that is worth a detour for the view. Return to the "Sous la Charvaz" crossroads.

(6) Take the path on the left that descends for a long way into the forest. You will reach a forest track.

(8) Turn left onto this track; leave it immediately 50m further on to descend the path on the right. This path gradually leaves the forest and joins an intersection. Turn left onto a good path which leads, 200m further on, to a small road near a chapel.

(9) Turn left onto the road first, then take a good path that forms a circular loop and reaches an intersection with another route option.

(10) Leave the path that leads to Ontex on your left and turn right. Continue left shortly afterwards, on the path that leads to the top of the village.

(11) Cross the village, descending to the left along the road, and continue. At the edge of the village, this road will make a large bend.

(12) 100 metres further on, leave the road and take the path on the left (unmarked), which initially climbs slightly before descending to the road. Follow it to the left for a short distance.

(13) Leave it again and turn left onto the Sentier du Saut de l'Âne. Descend this winding path until you reach a crossroads.

(14) Take the right path on the left towards Jongieux le Haut. A long, gentle descent will take you to the vineyards above the village. Cross the village downhill to reach the main road (D210).

(15) Follow the departmental road, turning left for 200 metres.

(16) Leave the road and take the small road on the left, which quickly turns into a slightly hilly path through the vineyards, leading back to Billième.

(1) Continue straight ahead and follow the same route as on the way out to reach the car park, which is now only 400 metres away (S/E).

The names of several points of passage on the ground do not correspond with the map.
From Ontex, it is very difficult to find your way around. A lot of details are missing.
Apart from that, it's a very beautiful hike with magnificent views of Mont Blanc and Lake Bourget.

This beautiful hike allows you to explore the eastern and western slopes of Mont de la Charvaz. What's more, the summit offers a 360° view of various mountain ranges! Taken in autumn, starting out in thick fog, this route rises above the clouds despite the moderate altitude of the peaks.
Note that it is possible, with a few hundred extra metres, to reach a magnificent viewpoint over Lake Bourget: at point 9, continue straight on the tarmac road towards Ontex until you reach a viewpoint (equipped with tables 😊), then turn around and resume the hike.
Otherwise, apart from the continuous climb at the beginning, the well-described hike is not difficult.
Thanks to the author.

Did this hike in rainy weather, got caught in the first downpour under Charvaz, the second when arriving at Ontex, which was very heavy. The descents were difficult and very slippery. At point 9, I decided to take the alternative route to point 10 to cut the length of the route by two kilometres given the weather, but it was steep and slippery. Fortunately, it wasn't long. Other than that, it was a beautiful hike. From point 8, be careful not to miss the path that branches off to the right, as it is somewhat hidden by tall grass. No comments from other hikers on this route. 15 km for 955 m elevation gain and 4 hours 25 minutes.

Nothing more to add to what has already been said.
As for the number of people on the route, I answered yes, because we encountered about fifty mountain bikers that day. Is this normal? Was it an event? Otherwise, there were six or seven hikers.

Thank you for this post!

It's a beautiful walk, mostly under trees, which is nice when it's very hot.
The view from the summit is well worth the detour...

Starting from Ontex, this round trip takes you to the summit of Charnaz, offering great views and easy access for children, with only 10 km there and back and a 550 m elevation gain. The route is entirely in the woods, with 50% on trails and 50% on tracks.
This part of the route is of average interest in terms of the trail, as it is entirely in the woods with only a few viewpoints, but the summit with its view of Le Chat and L'Epine is worth the effort, as is the panoramic view of the Jongieux vineyards.

A lovely walk with beautiful views from the top of Charvaz, despite a few clouds in the valley above Ontex and the vineyards of Jongieux and Billieme.
Perhaps a little monotonous on the last part, but a good day outdoors.

Route starting from BILLIEME, fairly even elevation, not difficult, but mostly in the woods,
very few views along the route, normally superb views at Mont Charvaz; but not on that day; however, we were above a sea of clouds, which formed a gigantic waterfall from which the Dent du Chat emerged. MAGNIFICENT

The start of the hike is poorly explained. In fact, you just need to walk up the road to the hairpin bend (about 50 metres) and then follow the signs for Mont (yellow sign and yellow and green markings). After a fairly steep climb, you will reach a crossroads where La Chavaz is signposted. The last part of the route is through the trees, following a trail that is sometimes difficult to see. The view from the summit (on the right when you reach the last crossroads) is superb.

There is a steep slope, but it ends well. The descents are much worse. Take plenty of water with you as there is no possibility of replenishing your supplies.

I only did part of the route as I joined the descent at the Col du Chat. Magnificent panoramas.
The part I used was very good in terms of the GPX file.

A very beautiful hike that is not very high in altitude, feasible all year round, done in superb weather.

A superb walk with a magnificent view from the summit of La Charvaz.
We set off from Ontex towards Jongieux to spread out the descent.
A beautiful crossing through the vineyards.

A very good day with beautiful, warm sunshine.
