Circular around Lhuis, between Milieu and Ansolin

This 15 km circular route around Lhuis will take you along an old tramway, overlooking a beautiful pond, following typical streams, observing a resurgence and crossing a scree slope. Several viewpoints over the Rhône and its valley, the Creys nuclear power plant and the Tentanet mountain make this hike very attractive.

Description of the walk

Starting point: Place de la Gare, at the site of the old railway station.

(S/E) Head west and take the small bridge over the stream. Cross Rue des Moulins and follow the old tram line.

(1) Leave the path on the left and continue along the old tram line. Stay on this path, heading north-west, which offers several views of the Rhône valley and the Creys-Malville nuclear power plant. Pass between the rocks that were specially cut for the tram to pass through. Leave the access to a quarry on the right.

(2) Don't miss the path on the right that leads to Millieu. It is steep and quite difficult if the ground is wet. At a grassy clearing, turn right uphill (do not continue straight ahead).

(3) At the next intersection, take the wide path to the right at an acute angle. Stay on this path for about 1 km, heading south-southeast then east-southeast.

(4) Take a path on the left (east) marked in yellow (markings will continue until the end). The start of the path is not very visible, so pay attention. The path descends slightly and turns left. Continue downhill and pass the viewpoint overlooking Tentanet Mountain, the hamlet of Millieu and its pond. Join a wide path and turn right. The path then turns left.

(5) At the junction with the D79, continue straight on along Montée du Ponton, following the stream (noteworthy wash house). After about 50 metres, leave the road and take the path straight ahead that runs alongside the stream for 200 metres (remarkable and relaxing landscape). After 200 metres, leave the banks of the stream, leave the path on the left and take the yellow marked trail in the centre. Join a path that you take to the right, crossing the stream, then stay on the right until you reach the D41. Follow the road to the left for 50 metres.

(6) Take the path on the right towards Saint-Martin. Then, keeping in the same direction, cross the meadow, keeping to the left.

(7) A small stream crosses your path: if you follow this stream upstream for a few metres, you can see the hole in the mountain where it springs from. Continue along the main path and, a little further on, cross a scree slope.

(8) Pass an arboretum (where you can take shelter and have a snack). At the next crossroads, turn left and go uphill. Then join a path and follow it downhill to the right until you reach Saint-Martin. Turn left in front of a pottery shop and continue along the path (Sentier de la Chèvre) which goes uphill and passes behind a water tower. Continue on level ground.

(9) Turn right (south) downhill. At the next crossroads, turn right again towards Lhuis, then immediately left. Take a very steep path downhill towards Ansolin. Take the Ansolin road on the left (east).

(10) At the cross, take the road that descends to the right. Cross the hamlet of Le Golet, following the wall on your right. At the end of the wall, take the path on the right. Continue to the Groslée bridge road.

(11) At the crossroads, cross straight ahead onto the dirt track and, after about 20 metres, take the path on the right towards Lhuis. At the next crossroads, take the path on the left. Then turn left again 400 metres further on and finally right towards Lhuis (north-west).

(12) The path is on the left, not very visible at first, marked by a large oak tree on the left of the road. Cross the grassy clearing; further on, a very visible yellow mark helps you find your way. Reach the Rix road and turn left (south-west). The road forms an S-shape. At the end of the bend, leave the road and take the wide path on the right towards the west. After 700 metres of easy walking, and after passing a large house on the left, you will reach a crossroads with a cross and a fountain.

(13) Then follow the road on the left. Cross the hamlet of Le Connand. At the end of the road, first turn right then left. Shortly afterwards, turn left again to reach Place de la Gare (S/E).

Notes

The quality of the springs encountered along the way cannot be guaranteed, except for the fountain near the crossroads at the end of the trail.
Some slopes are steep, the ground can be slippery and the path is sometimes narrow, so it is advisable to be well equipped (good shoes, walking sticks).
If you are planning a day hike, the meadow after point (6) or the arboretum at point (8) are ideal. In this case, plan to set off at around 9.30am.
The hike can easily be done in two stages, returning to the starting point at Lhuis a few hundred metres before the point (8).

Worth a visit

In each hamlet, you will find ovens and wash houses. The hamlet of Saint-Martin is very pretty in the summer and is well worth a visit.
It is sometimes possible to visit the Saint-Martin pottery. Please enquire before setting off.
There is a restaurant in the centre of the village.
The Naray farm sells directly to the public.
The Lhuis town hall also serves as a tourist office.

A wonderful hike – we didn’t see a soul.
The route was clearly marked. Stunning views from the cross-marked points.

A very beautiful circular route, the tram route is very pleasant, the slightly steep climb adds a little difficulty to this route but it is still a beautiful walk.
There are some beautiful views, we only met three people along the way, and the streams and waterfalls were magnificent.
We took our time, stopping to take photos and let our dog run around and swim, and it took us 4½ hours.
The route is very well marked.
The break on the way back at the Lhuis inn was very pleasant and welcoming.
A wonderful day.

Route completed on 7 October 2024.
In the route description, the climb between points 2 and 3 is described as "steep and quite difficult if the ground is wet". The slope is indeed particularly steep and difficult to access, especially in rainy weather, or even in any weather, given the very steep slope, for inexperienced hikers.
This section can be bypassed by going directly from the start to point 4.
I haven't tried it, but it's worth a shot.
The arboretum is indeed a great place for a picnic, with a covered shelter in case of rain.

Route to be taken in dry weather
Trail not very clear, especially in the first part
Otherwise very interesting
The arboretum is the perfect place for a picnic!
But be careful at point 8, where the path turns left before the arboretum hut

A beautiful, well-marked trail.
Some paths are disappearing in the forest, overgrown with vegetation (40% incline).
You have to search a little, but the GPS was a great help in terms of reliability.
The pretty village of St Martin is very pleasant, and walking through it is more interesting than the view from the 'water hole'.
It's a shame there are no open terraces to cool off at LHUIS.
I recommend this beautiful hike.

A very beautiful hike, we thoroughly enjoyed it. I highly recommend it. After the heavy rains we had, the water levels in the rivers were quite high.

The number of kilometres is correct in the description, as is the elevation gain. You need to pay attention to the markings at the start of the route (not always clearly visible), but the second part is well signposted (from Millieu onwards). A very pretty hike with beautiful views. The picnic spot at point 8 (arboretum) is great, with a wooden hut for picnics and a lovely view. Beautiful view of the hamlet of Millieu and its pond. The path along the stream (point 5) is very pretty. The tramway that passes between the carved rocks is pretty. This hike is really relaxing. At the end of the route, visit the village of Lhuis. I recommend doing this hike in good weather because the climb to Millieu (steep path, 40% gradient over 600 metres) would be very slippery if it rains. To conclude, this beautiful route is a feast for the eyes.

Hike done during the week and in winter, so very quiet. Beautiful scenery. Takes less than 4 hours to complete.

Halfway through the circular (return to LHUIS without passing through ANSOLIN). Description: very good, except perhaps above MILLIEU where the distances are not entirely accurate.
Waypoints with kilometre indications are welcome in the few disputed areas (provided you have a GPS meter yourself).
The area is absolutely peaceful (except for the area overlooking a motocross route!), and LHUIS is a village that is well worth a visit.

A beautiful hike with some steep climbs. Most of the route is under trees, but we got very hot because we set off a little late. I'm not sure about the length of the route. We stopped at St-Martin to get some water from a beautiful fountain with very fresh water. My altimeter showed that we had covered 12 km, so we decided to take the road back to Lhuis. It was too hot and a little late to do the circular route. In my opinion, it must be at least 17 km.

A beautiful, varied circular loop with no difficulty. We cut across at the Ansolin descent at point 10 (path on the right) to reach Lhuis directly. The description and route are perfect.

Hello,
Beautiful route, very varied with lovely views.
The natural surroundings are beautiful, but it's a shame that some locals use it as a rubbish tip (along the tram route, for example).
We took the shortened circular before point 8.
Thank you for introducing us to this route, which we will do in its entirety next time.
