Mont de la Charvaz, loop from Billième

Among the many access routes to Mont de la Charvaz, this loop takes the most direct route to the summit, via its steep western face, and descends via gentler forest paths. The view from the summit over the Avant Pays Savoyard and the surrounding mountains is extensive.

Description of the walk

From Billième, reached from Yenne or Saint Jean-de-Chevelu, climb to the hamlet of Les Jacquins, cross it and park at the end of the tarmac road.

(S/E) Take the gravel road that continues on from there. After a wide bend, it turns south-east and gradually climbs. At the edge of the forest, it turns left and reaches the Mollairon crossroads.

(1) Take a forest path on the left, heading north-west. It climbs above the fields of Santourin. At the first bend, take the marked path on the right, which leads to a second crossroads 200 metres further on.

Alternative: at the first bend, you can also continue straight ahead on an old mule track: be sure to continue climbing to the right when you reach the first path to join the route described above, before the (3).
.
(2) Leave the marked path to the right towards Sur le Crêtet and climb to the left towards the north-west, under a rocky outcrop visible through the trees. At the next junction, leave the path that descends slightly to the left and turn right to continue climbing.

After a short flat section, the path veers right to climb a little more directly up the slope to a crossroads.

(3) The main trail turns left to descend towards Ontex. However, you must take the steep path opposite that climbs straight up the slope, marked by a cairn and two blue dots (this fairly discreet marking accompanies the rest of the climb).

After climbing up a couloir, the trail veers to the right and then winds its way up to pass over a first rocky outcrop. It climbs up the slope to the right to pass over a second outcrop before veering east to reach a pass between the two peaks.

(4) From this pass, where the trails cross, first climb to the left for a round trip to the geographical summit, then climb to the right for a round trip to the "natural viewing platform".

Descend eastwards to a valley where you leave the path to Ontex on the left and descend on the right into the forest. The bottom of the descent becomes steeper, but a new path has been laid out to make a few hairpin bends before arriving at a forest track at a place called Le Poulailler.

(5) Turn right and descend this track, which veers left along a small valley on the ridge, at the end of which it winds right and then left.

(6) Take the right path, which descends under the rocky ridge, turns right and reaches a crossroads at Sur le Crêtet.

Alternative route: in the bend (6) on the left, a discreet cairn marks the start of a shortcut that descends straight down the slope towards Sur le Crêtet (wear sturdy footwear to avoid twisting your ankle).

(7) Turn left to continue down the forest track, which winds around and reaches the crossroads at Chapieu.

Alternative: at (7), you can also continue straight ahead to join the ascent route at (2)

(8) Turn right to descend to the junction on the way out.

(1) Follow the gravel road in the opposite direction to the starting point (S/E).

Notes

This is a half-day hike that is pleasant in all seasons as the snow melts fairly quickly.

Almost the entire route is in wooded terrain. However, its western exposure beneath rocky outcrops means that the climb can be very hot in the afternoon, especially when the trees are still bare.

The section between (3) and (4) requires sturdy footwear to prevent slipping on the steep trail.

Worth a visit

The geographical summit offers views mainly to the east: Mont Blanc, Bauges, Lac du Bourget, etc.
The "natural viewing platform" offers the best views to the west: Avant-Pays Savoyard with Yenne, the Rhône valley and the Lagneux marshes, the vineyards of Jongieux and Billième, Mont Pilat, Grand Colombier and Bugey, Dent du Chat and Lacs de Chevelu, Chartreuse, Belledonne/Sept Laux, etc.

There are no difficulties on this route, which is sheltered from the crowds and features plenty of woodland, so it must be particularly pleasant in summer. Indeed, there’s a steep climb lasting just under an hour (if you take a few breaks and adopt a leisurely pace). The view from the summit is relaxing and magnificent; several groups can picnic without getting in each other’s way… and the descent is very gentle, following the route marked out by the trail marker. (Thanks to him.) We completed this walk in just over four hours, including a picnic: a wonderful memory!

A lovely loop above the hills of Marestel. Follow the directions indicated, as the last kilometre of the climb is extremely steep. Beautiful views at the top and an easy return.

I took the route in the opposite direction... and I wouldn't recommend it! The return trip was really tough with my weak knees. I had walking sticks, but I regretted it! Otherwise, it's a very simple and enjoyable trail. The only difficulty is the downhill slope on the way back.

A very beautiful loop, and we appreciated the shaded sections. Some lovely views on the way up and a beautiful viewpoint at the summit. The uphill section is challenging but can be completed without any technical difficulties.
We did it in the suggested direction and really enjoyed it.
Took 3 hours with breaks. There were only 5 hikers, which was very pleasant.

Do it as described, starting from the town hall car park +1km and 100m elevation gain, but parking spaces are guaranteed.
Very steep climb and walking poles are essential, especially on the last section, as already mentioned in previous comments. Good warm-up for the start of the season. Climb in less than 2 hours at a leisurely pace with breaks.
The route is peaceful, the only sounds being woodpeckers pecking at trees and, from time to time, aeroplanes landing at Le Bourget during the ski season.
Very beautiful view from the summit overlooking the sea of clouds on the Bugey side that day.

This route is very well marked; the Visorando trail is sufficient. We completed the ascent in 1 hour; it is true that it is quite steep in places, and the descent took 40 minutes on the trail. The ascent is through the woods, and the two viewpoints are magnificent.

Hello,

Very nice hike, but I agree with other comments that it should be done in the opposite direction. Be careful, there is a tricky section with cables on the side of the cliff!

From point (1) to point (4), the climb is steep, but with a few breaks it is manageable and well worth the effort. At point (4) you will have a beautiful view of Lac du Bourget, among other things. The descent is very gradual, and you are protected from the sun for a long time, with very little exposure in the vineyards. A pleasant walk, thank you.

A beautiful hike, the view is well worth the effort, and the last part of the climb on a single track is a detour worth taking.

Great hike done in the recommended direction, and I much prefer having a very steep but not very long climb, and especially not having to do this part downhill, which must be really tricky. If you take your time, it's fine! Magnificent view at the summit, thank you for this trail.

It is indeed preferable to do so in a clockwise direction.

There is no parking available at Les Jacquins or at the end of the tarmac road. You must start from the village of Billième.

A beautiful walk that is well worth it for the two superb viewpoints.
Between 3 and 4, the climb is a little steep but it's easy enough with the right footwear and, above all, walking sticks.
Overall, the route is shaded and fairly easy to follow.

Nice walk,
advice for keen hikers: do it in the opposite direction, as the climb on the west side
is very, very steep.
two beautiful viewpoints on the two peaks.
Start from the Billième car park.
