Pic d'Oliferne from Coisia

This hike begins with a steep climb, rewarded by numerous panoramic views of Lake Coiselet. It continues along a pleasant ridge with beautiful views and ends with a visit to the ruins of the medieval castle of Oliferne, which offers a 360° view, before descending back to the starting point.

Description of the walk

Park in the car park at the top of the main street in Coisia, where there are a few spaces available.
You can also park further south in the village

(S/E). Walk back down and take Rue du Centre on the left. At the next crossroads, turn left onto Chemin de la Chandelette.

(1) At the first three-way junction, turn right.

(2) At the next intersection, take the path on the left. Stay on this path heading north.

(3) At a fork, go left and continue north. Pass a spring and continue north (path not shown on the IGN map but present on the OSM map).

(4) At the crossroads, turn left and head west-southwest, then southwest.

(5) At the crossroads, at a place called Au-dessus des Puits, turn right (north) onto a good path.

(6) At the next crossroads, take a recent path on the right, marked in yellow. Wind your way through the woods for a long time, heading generally north-east (beautiful views of Lake Coiselet). The path makes a big turn to the left, then one to the right, finally leading to a wide white path.

(7) Follow this white path to the right and you will reach the Pic d'Oliferne car park.

(8) Climb up to the left (signpost indicating the direction of Molard de Justice). When the path turns right, leave it and take a path that climbs straight ahead. At the next fork, turn left and climb up to the ridge.

(9) Then turn left (south-southwest) and follow the gentler uphill ridge. Pass by a few viewpoints.

(10) At the last viewpoint, leave the ridge by heading left. Shortly afterwards, take the dirt track on the right and follow it to the next intersection.

(11) Turn left onto a path and continue east, ignoring the paths branching off to the sides.

(5) Back at Au-dessus-des-Puits, turn right (south) to climb up to Oliferne Castle.

(12) Walk around the site (the route is clockwise). There are numerous information panels along the castle route. Climb up the low wall to reach the platform with the castle ruins. Go to the end to admire the view of the Ain, read the information panels and discover the legends. Return via the ruins. Gradually descend.

(12) Retrace your steps to the Au-dessus-des-Puits crossroads.

(5) Then turn right and retrace your steps to return to the Coisia car park (A/D).

Notes

Map 3228OT is very useful.

Worth a visit

- Between (5) and (6), in good weather, you can see the Vouglans dam in the distance.

- Along the way, discover the partially restored Château d'Oliferne. There are many information panels about the château, its reconstruction, legends and the dams on the Ain.

- To see after the hike: dinosaur footprints on the rock face (marked by a sign). You can get there on foot from Coisia by taking the road to Thoirette, or by car. Limited parking available on site.
- By car, you can visit the two viewpoints on the Vouglans dam (one on each side of the Ain).
- The Romanesque church of St Hymetière is a short drive away. One of the most famous in the Jura.

A very good hike to avoid the heat, generally pleasant paths, well worth the detour.
You can avoid taking the same route downhill by heading straight down from the peak towards Coisia; there are several paths.
Thank you.

Pleasant walk through the woods. Beautiful view from the summit (and only at this point). Beautiful site of Oliferne Castle.

Despite a lot of undergrowth (which is normal given the altitude), this is an interesting hike because it is varied and offers views of Pic d'Oliferne and the Mollard de la Justice ridges.

The return journey can be made via a very passable path without retracing the same route as on the way there. At point 12, head slightly back towards point 11 and take a path that leads directly to point 1. The path is clear, but be careful as some sections are steep on the way down, although there are no particular difficulties.

E very beautiful hike... taken backwards: after parking at the cemetery (no spaces available in the village), we took thecircular option, via the RD60E1 and Les Fours à Chaux, before joining the yellow-marked route (and the steep climb up the forest road in the Coisia national forest). Admittedly a little monotonous, but allowing for a little morning introspection, it enabled us to avoid the climb between points 3 and 4, which was very slippery after the recent rains.
And then... we prefer circulars, in the opposite direction to our fellow hikers.

Thank you, I have corrected point 10.
I had also previously descended via Les Fours à Chaux, but did not choose this option. I prefer to view the dinosaur tracks by car from Coisia.

Today's hike included a slight variation on the return leg after the point (11) via Fours à Chaux (the motivation being to complete a circular loop while passing directly in front of the dinosaur footprints).
Some parts of the route were familiar to me (Château d'Oliferne and the Molard de la Justice ridges), but I had never had the opportunity to do the sections between Coisia and Château d'Oliferne, or the eastern ridges towards Boutavant, until today.

Overall, the route was a positive experience: I particularly enjoyed the section with its many views of Lake Coiselet after the point (6).
The decision to return via Fours à Chaux was not the best idea: the route was certainly very easy, but it was rather monotonous and a little too road-based (unlikely to choose this option again).

Many thanks to the author of the route.

NB: a small detail: after the point (10) (last viewpoint), the route follows a dirt track rather than a tarmac road.

A very pleasant hike with beautiful views. The panoramic view from Oliferne Castle is a must-see, not to be missed. The view is breathtaking: valleys, rivers, forest-covered mountains, lots of relief, which is what makes the Jura so enjoyable. The route along the ridges towards Boutavent is very pleasant, with views of Lake Coiselet, the Vouglans dam in the distance, Chancia, Moncusel, etc. The paths are very easy to walk on. We took a few liberties with the route, taking a few shortcuts, without going as far as Boutavent, which we already knew. Our legs were a little tired at the end of the route, but there were no technical difficulties.
Thanks to whoever suggested this route, we highly recommend it.

A very pleasant hike, alternating between woodland and ridges, ascents and descents – in short, we thoroughly enjoyed ourselves! From the site of Oliferne Castle, there is a beautiful view of the lake and the Vouglans dam. A lovely area to explore.
