The source of the Lison and the Belvédère du Vieux Château

Discover the charm of Nans-sous-Sainte-Anne and its old houses, nestled in the natural setting of the remote valley, its Taillanderie. Then there is the Lison, mystical and wild at the foot of a vertiginous rocky cirque, after a tortuous underground journey, gushing forth in the blue-green plume of its never-ending waterfall, the wild cathedral of the Sarrazine cave, the Creux Billard and finally the belvedere of the Vieux Château.

Description of the walk

Parking is available in Nans-sous-Saint-Anne, opposite or to the left of the town hall. Yellow and blue signposts.

(S/E) Head towards the church, which is worth a visit for its beautiful statues. Turn right up Rue du Château. At the foot of the beautiful turreted house, turn left up Rue Cretin (signposted Le Vernau). At the fountain, turn left towards Source du Verneau (green sign), passing beautiful old houses. After a small bridge, climb up to the waterfall on the right via a small stony path and a few steps. At the metal footbridge, despite the yellow and blue cross, continue with caution along the steep and slippery path on the left.

(1) Then return to the centre of the village, pass the church and the town hall/school and head towards the Sainte-Anne — Crouzet Migette hike. After the bridge over the Lison, follow the signs to the taillanderie.

(2) At the fountain, turn left. After a small stone bridge, follow the signs for Source du Lison — Creux Billard — Grotte Sarrazine on the left.

(3) At the lodge, the path forks; follow the left fork that runs alongside the Lison. If you wish to visit the Taillanderie, take the right fork.

(4) Go past a wooden footbridge and head towards the Grotte Sarrazine, a "wild cathedral" with a large archway 100 metres high and 30 metres wide carved into the limestone rock. Return and cross a footbridge, then a second one, and turn right at the Lison spring. Take the small footbridge opposite the spring and head right. Follow the signs to Creux Billard, then turn back.

(5) At the signpost, head towards Chêne remarquable — Nans-sous-Sainte-Anne along the path that climbs the hillside, following the yellow and blue markings. At the foot of a huge oak tree, turn right towards Crouzet-Migette.

(6) You will reach the D103, which you follow to the right until the first hairpin bend. Along the way, there is a viewpoint over the valley and the village of Nans.

(7) At the wooden cross, turn left onto the road in the bend and follow the GRP®. After 200 metres, the trail turns left onto a path that climbs through the forest.

(8) Join a carriage road that continues along Rue du Derouchou and pass in front of the Chevrie buildings. You will arrive at the D103.

(9) Cross it and catch up with the GRP® trail opposite, which descends to the right and reaches a road.

(10) Take the left-hand track. Be careful! Immediately after crossing the Château Renaud stream, leave the stony road and take a small stony path that climbs up to the right. It quickly becomes a more or less well-maintained and slippery track.

(11) You will reach a gravel path which you follow downhill to the right. Follow the GR® which runs along the edge of the pasture.

(12) The path seems to end in a cul-de-sac. Look for a small trail on the right that winds through the tall grass. You will enter the woods. Look for a sign for Nans-sous-Sainte-Anne on one of the first trees. The path then forks. Take the path uphill towards the viewpoint (sign) and follow the markings and crosses indicating which paths are closed.

(13) You will come to a crossroads marked by three signs. Take the left-hand path towards Vestige du Vieux Château — Belvédère.

(14) Turn back. About 700 m after the viewpoint, after a slight climb and about 20 steps after a sign for Vestige du Vieux Château, look for a small path on the right (a little further on, you will see the sign for Nans-sous-Sainte-Anne, which is not very visible from the path). If you miss it, don't panic, continue to the previous crossroads and go down to the right; the two paths rejoin. Go down to the point where you see the sign for 'Nans-sous-Sainte-Anne' and continue downhill to the left towards Nans.

(15) As you leave the woods, follow the sound of water and you will see the old axe factory and its water wheel through the branches. You will soon reach the lodge and return to the centre of the village and the car park (S/E).

Notes

The route includes unsecured viewpoints and rocky, sometimes slippery paths. Walkers should therefore take care and be cautious, as rock outcrops could cause them to trip. Good footwear is essential and walking sticks are recommended.

Worth a visit

Nans-Sous-Sainte-Anne: Nestled in a green valley in the Doubs, the taillanderie, a farm-workshop producing scythes and cutting tools, was founded in 1798. It continues to operate today, introducing visitors to the traditional methods of making scythes and sickles.

Salins-Les-Bains: The large saltworks and the salt museum. The saltworks of Salins-les-Bains have played a key role in the history of the town and the region. This major site of Franche-Comté's industrial heritage has received several national and international awards.

This route is only used at the source of the Lison, the cave and the Billard hollow. The rest of the route is very quiet.
940 metres of elevation gain and 13.3 km. A beautiful hike accessible to everyone. No difficulty.

A beautiful hike, especially when there is no foliage to hide the views.
I started from Crouzet Migette town hall (PKG) and didn't do the route from the start to point 3. I just missed the Verneau waterfall. Done clockwise, it avoids the very steep climb. Thanks for the suggestion

very beautiful route, a few minor observations
access to the source of the Verneau is prohibited, as indicated by a notice from the town hall (dangerous road!)
point 10 (the park): the signs seem to be poorly positioned and Nans sous Ste Anne is not indicated. Just go straight down; we turned left and arrived at point 11. The climb was difficult and slippery, so we went back down to point 10 and returned to Nans.
have a good day's exercise!

A very beautiful hike, without any difficulties. With stunning views and magnificent spots such as the Varneau waterfall, the Sarrazine cave, the Creux Billard and the source of the Lison.
Very few people in February, and a superb sunny day.

A really nice trail, enhanced by the source of the Lison, the Creux Billard and the Sarrazine cave... magnificent natural sites. You walk alongside the Lison for a while in incredible surroundings. There are some steep climbs and descents, but they are manageable. Beautiful spots in the forest, with a pine forest to walk through...i started my walk with a temperature of -2, so some parts of the forest were completely frozen, but it was really beautiful! I didn't make it to the castle viewpoint, but I'll save that for next time. I recommend this walk. The signposting is easy to follow.

I followed this hike from start to finish. It was a wonderful discovery of the village of Nans sous St Anne. The hike is very pleasant, with the Varneau waterfall, Crotte Sarrasine and the source of the Lison to discover. With a few detours, the hike is 17 km long with a 600 m elevation gain. You need to be in good physical condition. I completed it in 4 hours.

Far from the persistent November fog in the plains, this hike in the foothills of the Jura offers a varied route with beautiful views of the Nans-sous-Sainte-Anne valley. Regarding point 12, "Belvédère du Vieux Château", don't hesitate to make the round trip, it's worth the detour! The view is magnificent and the climb is good for your legs and your cardio!
In wet weather, such as in November, wear shoes with good treaded soles.

A beautiful hike, especially in the first part at the source of the Vernau and Lison rivers in June when there is plenty of water.
The second part is less interesting: there are no ruins, only the belvedere is worth the effort.

Beautiful route and well signposted. Very beautiful landscape in a bucolic setting. Mainly shaded and pleasant in hot weather. Source of the Lison (beautiful waterfall), then on to La Grotte Sarrazine (superb) and further on to Creux Billard, which is worth the detour. No interest in the castle ruins and its belvedere (which I didn't want to visit)
Points 10 to 13 (without going through 11 & 12) are steep descents with lots of stones, quite wet and slippery in rainy weather!
This hike requires good footwear.

With the current abundance of rain, the spring is impressive and the bubbling flow and Creux Billard are definitely worth a few extra steps, but be careful as it can be very slippery and there is no protection for children.

A very beautiful hike, with some fairly busy sections (the source of the Lison, of course, but also the Sarrazine cave: magnificent!!!), and very few people or no one at all on the rest of the route.
For the source of the Verneau, don't be afraid to get your feet wet, it's worth it, but the rocks are very slippery.
i then combined this with the Pont du Diable and Montmahoux hike, starting from point 12.

A beautiful, shaded hike with several detours along the way to see interesting sites. Only the last stretch to the castle ruins and viewpoint is an additional 2 km of difficult uphill and downhill walking with little of interest.

A very picturesque hike with lots of points of interest.
Despite the high temperatures, the hike was mostly in the shade and along streams, which was very much appreciated.

Magnificent hike with spectacular natural sites: Sarrazine cave, source of the Lison river, Creux Billard.
At point 9: there is no point in "opening the gate, crossing the meadow and then closing it again" = a well-marked path at the edge of the woods follows this route.
Did not do points 11 and 12 at the viewpoint.
Point 13: guided tour of the Taillanderie de Nans, an extraordinary place with buildings, water wheels, forges, tools and, of course, very informative explanations from our guide, who was happy to show us how some things work and how they are done! A must-see factory museum in a lush green setting surrounded by water.
