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).
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.
