La Roche Thiébaut, La Facle and Les Blocs Erratiques

Three viewpoints allow you to discover the Ornans mountains from the left bank of the Loue, Mont d'Ornans, Roche Thiébaut and Grand Barmaud, before returning to the valley by winding your way through La Facle, a narrow and picturesque fault that cuts into the cliff, and ending at the erratic boulders, geological curiosities, masses of stone weighing over 130 tonnes, transported by glaciers 600,000 years ago.

Description of the walk

(S/E) Swimming pool car park, Rue de Lonege in Ornans. Yellow-blue and yellow-red signposts.

Leave Ornans on the D.241, with your back to the swimming pool. Go past the roundabout, leaving the signposted Chauveroche path on your left. At the Passage de Sevirey sign, turn left towards Monts d'Ornans - Grand Barmaud. Take the Chassagne road.

(1) At the last house, turn left onto the gravel path. You will soon pass some beautiful rocks. After the third hairpin bend, at the top, where there are numerous signs, look out for the red cross of a mountain bike signpost in front of you and climb up a path on the left, up the wooded hillside towards Chassagne-Saint-Denis.

(2) When the path reaches a plateau and turns 90° to the right, a path branches off to the left towards the small opening of the unsecured Mont d'Ornans viewpoint (altitude 509 m). Head back towards the VTT28 circuit. Like a wolf, you will emerge from the woods and cross a meadow.

(3) When the path becomes stony at a signpost, leave the trail and head into the field on the right towards the edge of the woods, following the power line. At the edge, the path becomes stony and you will find the mountain bike trail again. You will quickly rejoin the path you left earlier to climb Mont d'Ornans. Turn left, still following the MTB28 route.

(4) One kilometre further on, at two mountain bike markers, the path splits, forming an oval shape. Keep right towards the edge of the cliffs and the Belvédère de Barmaud. Leave the viewpoint via the small tarmac road which quickly joins the D.241. Follow this road to the left for about ten metres, then turn right onto the stony path.

(5) When the path turns 90° to the left, look for a small trail on the right (ONF sign no. 6, direction La Facle) that enters the woods and leads you to the third viewpoint, the most beautiful, overlooking Notre-Dame du Chêne, La Roche du Grand, the old Tacot viaduct and the Brême valley. At the first viewpoint, turn left, carefully skirting the edge to reach the second viewpoint, then continue along the cliffs. The sharp limestone pavement trail is treacherous for ankles.

(6) At the ONF signpost no. 10, you will arrive at La Facle, a narrow, picturesque fault that cuts into the cliff and allows you to descend back into the valley. Leave the signposts behind. About fifty steps after this beautiful path merges with a stream bed, take a path climbing up to the right. You will soon arrive at a pleasant, quiet paved road where you will turn right and continue for 300 metres.

(7) When the road begins to descend slightly, look for a large green sign on the right marking the start of the path that will lead you to the erratic blocks, enormous masses of stone weighing over 130 tonnes carried by the glacier. Go through a fence using a log ladder and climb up to the right to reach the first boulder. I must admit that I couldn't find the second one, even though 145 tonnes of rock shouldn't be that easy to miss. If you find it, please let us know here. Return to the ladder and head towards the pasture, then follow the upper edge on your right to enjoy a beautiful view of the Roche du Grand. Then descend towards the passage at the end of the meadow to find the road that will take you back to Ornans.

(8) You will pass the campsite. While the small road that took us back to Ornans was pleasant, Rue du Chanet is endless, but it does offer some nice views of the mountains and the castle. You will join the D.241 and descend to the left towards the roundabout and the car park (S/E)

hello, to find the path to the fault, once you arrive at the pretty little wood, you will see a sign pointing towards Château St Denis, I think, and the path to the fault is just before this sign on the right... you will see it going down between the rocks

Walk followed with GPX track, beautiful views of the valley, lack of attention to the fault, but we turned back. Only one erratic block found, covered by vegetation. Pleasant hike in the forest.

Hike followed with GPX route, only one problem finding our way at the fault line, we went round in circles a bit! Beautiful views, not too difficult, be careful after the descent from the fault line, at the stream, take the path on the right, we went down a little too far but it was easy to get back on the path... as for the erratic boulders at the end of the route, they're not very interesting, they're not very accessible and there are lots of brambles....
Overall, it was a nice walk, and with the snow it was even more beautiful....
I would still give this hike an average rating.
Thanks for suggesting this walk.

The first part of the route is very pleasant and the description is accurate.
Once we reach La Facle, we easily find the narrow fault line and have to descend quite a long way to find the path that climbs up to the right. Unfortunately, this path is difficult in places, as there are many trees blocking the way.
The path could do with some clearing.
The small tarmac road is reached after at least 30 minutes of walking along the path.
The views would benefit from being cleared.
A beautiful walk in the forest to be enjoyed in dry weather.

The description needs to be updated.
S/E. The swimming pool is no longer on Rue de Lonège (and this is not a recent change!). The car park (unpaved) is still there, of course.
Between points 3 and 4, the presence of a tree-top adventure park should be mentioned.

No. 4. "Leave the viewpoint via the small tarmac road..." There are only a few traces of tarmac left! (But this does not prevent you from walking!).
When you reach the D.241, the start of the gravel path is almost opposite the arrival point.

No. 6. This paragraph needs to be reworded to make it clearer and more precise. Where do the "fifty steps" start and where does the "beautiful path merge..."?

The same applies to No. 7. Access to the two erratic boulders is possible, but they are still very overgrown (brambles, etc.). However, this is probably the responsibility of Ornans Town Hall.

The name "La Roche Thiébaut" is mentioned in the title of the hike, but there is no mention of it in the description.

three very pretty parish-specific gazebos offering a general view of the outskirts of Ornans. A very pleasant walk for the first 7 km, unfortunately followed by a descent completely blocked by a multitude of uprooted trees, making the path invisible in several places. We therefore got lost
fortunately, with the app, we were able to find our way back
after returning to the road and seeing the comments telling me that the end of the route was a bit long, I preferred to go down immediately along the Loue and return via the mountain bike trail to the start. The trail was a parish specific to Brittany. Thank you for this beautiful walk

A pleasant, shaded hike with some lovely views of the Loue Valley and an interesting descent into the Facle fault.
It's true that the end of the trail, which ends on a road in a housing estate, is less interesting. The erratic boulders appear to be in the process of being cleared of vegetation.

A very pretty hike in dry weather, but after a day of continuous rain, the ground was a little slippery in places... The hike runs alongside the tree-top adventure park where tables are available for walkers to picnic if necessary. After the clearing, a multitude of streams gushed out of the rock, making progress a little difficult. Be careful, the path on the right at point 6 just after the clearing is blocked by fallen trees. It's not easy to get past them, but there's no choice if you want to continue the hike. Then, as the path is no longer marked, simply follow the trail left by other hikers until you reach the small tarmac road, which takes a while to appear! The erratic boulders are a little further on, about fifty metres apart. The one on the left is covered with vegetation and probably not very visible in summer. Note that at this time of year, the route is mostly in the shade, as the sun is too low to be visible. Dress accordingly!

This hike is good, with varied landscapes and superb viewpoints that you never tire of
however, point 6 is difficult to spot for hikers who aren't paying attention
overall, a beautiful hike

Access to the blocks has been completely disrupted by earthworks and road widening. The first block remains clearly visible, while the second, about fifty metres below, in a recently fenced-off field, is partially covered with vegetation but difficult to reach unless you climb over the wire fence.
It is a pity that this site is not better promoted for tourism!

Be careful at the start of the hike, which is not near the current swimming pool, but near the old swimming pool (out of service) not far from the public secondary school! It is not in the same area of Ornans at all...
It's best to do this hike in dry weather, otherwise the ground and stones are slippery in many places (you have to cross a stream)
A lovely walk, mostly in the shade! The views of Ornans aren't spectacular... but it's nice

A beautiful hike with no particular difficulties, accessible to all, offering superb views of Ornans and its valley.
The paths are pleasant. We even continued our walk to the Château St. Denis, above Scey en Varais. Once we reached La Facle, we continued to the Château St. Denis by simply following the signs. We descended from the castle ruins on the right and followed the marked path to find the small paved road that took us back to Ornans.

A total of 15.2 km of pleasure.

Best regards.

Be careful not to miss the descent through the fault. Otherwise, continue to the hunting hut, have a picnic, and turn back. Similarly, in the riverbed, a few metres before turning right and heading uphill. Thank you.
