Description of the walk

(S) Starting out from the Biathlon stadium at Plans d’Hotonnes.

(1) Take the path to the south towards l’Oreille, go past the farm and carry on due east until you reach the "Tour du Valromey" which takes you under the power lines.

(2) Continue northeast for 300m then turn left and head due north until you reach the "Croix des Terments."

(3) Take the GR9 to the north until you reach the "Ferme du Tumet", making a short detour on your way (return trip) to the "Crêt du Nu" viewpoint (4). Be careful as this little path on the right is not very well marked.

(5) In "Tumet" turn left and continue southwest along the footpath which takes you within 200m of the “Grange à Lucien.” Carry straight on until you reach the crossing where you will need to head due east to reach the "Gouffre de le Bauche" (6), a site that is not very impressive and that is hard to find.

(7) Carry on southwest again towards "Granges Charpy" and then carry on down the path until you reach the tarmacked road, then cross the D396 to reach the biathlon stadium.

Beautiful walk, forests, plateau, viewpoints.
Be careful on the plateau, in the second part of the walk, to follow the GPS, uncertain landmarks, poorly marked paths.
Deserves a very good rating.

A beautiful, wild route with very few roads.
Use of the app is essential, particularly for the start of the route.

Nice walk with no particular difficulties, and a magnificent view of the Alps, Bugey and Sorgia.
A little difficulty finding the way at point 7, but the app's guidance makes it easy to get around.

It would be useful to specify that the start car park is the biathlon car park, next to the biathlon stadium. A large car park on the right as you arrive at the Plans d'Hotonnes resort could be misleading and lead you to look for the starting point.

We'll do this walk again in fine weather. Not always easy to follow the route if you don't have GPS

trail completed at the end of november 2023: forestry work, logging making the return journey difficult (mud stream to cross!)
easy and very pleasant circuit, beautiful view of mont blanc

We did this walk in May in search of spring flora, the daffodils were a bit late but we discovered other species identified thanks to Plan Net. The route is very pleasant and easy to follow, except at the start after the bend towards the farm, where there are a number of different routes. We found the chasm, which is well hidden and allowed us to leave the wide path. You come across some beautiful trees and it's a great route for the whole family.

It's a shame not to make the diversions to Beauregard from the Croix des Terments: follow a VERY nice path lined with beech trees, then climb to the orientation table. Continue along the path to the summit, then rejoin the track towards the Cha. It's obvious on the ground.
Crêt du Nu: signposted summit, then take the path on the right to see the panorama. Nice spot for a picnic. The view is clear.

A very pretty route, whether on foot, mountain bike or horseback. Very pleasant forest route. To be repeated on snowshoes this winter.
