Description of the walk

Park on the ridge road above the junction with the road leading to Mont Thou.

(S/E) Start the ascent of Mont Thou via the tarmac road (watch out for cars, bikes, motorbikes... this coexistence will not last long...)
Reach the orientation table and enjoy the view stretching from Lyon to the Alps in good weather.

(1) Then set off again on the path that descends through the field just below the orientation table.

(2) At the crossroads, take the path that goes through the bushes and into the undergrowth, and follow this single track until you reach the road at a crossroads and car park. Take the road opposite that descends towards the hamlet of Mont Thou.

(3) Take the path on the left to reach a field. Follow the path on the right to reach a wide track that will take you to the entrance to the hamlet of Mont Thou. Walk up through the hamlet towards the road, which you will follow to the bend.

(4) Take the path down towards Clos de la Rosette. Follow this path and admire the stone drystone shelters that line it. They have been restored by local associations. You will come to a wider path. At this point, go up to the right until you reach the ridge road.

(5) Turn right to follow the ridge road for about a hundred metres and take the road on the left. Immediately turn right to cross a small hamlet and rejoin the ridge road. Then turn left.

(6) In the bend, climb up the hard shoulder to rejoin the poorly surfaced road known as 'de Saint-Cyr à Poleymieux'. Then continue straight ahead until you reach the starting point (S/E).

A superb, easy walk, discovering drystone shelters and stone-walled paths near Lyon.

A beautifully shaded route to remember for warmer periods.
Completed in 1½ hours, with a few muddy and slippery sections following the previous night's rain.
There are many paths crossing the route.
Beautiful view of Lyon and very accessible route.

the paths leading from the summit of Mont Thou are not very visible. Some pretty drystone shelters. Do not attempt this in January: very muddy and slippery.
there's a big, somewhat gruelling climb at the end: be prepared!

A pleasant route... but extremely muddy and slippery on this thawing Sunday... The return journey is in the shade, so recommended in hot weather. Recommended route for a Sunday afternoon with the family...

A very pleasant, easy walk that takes about an hour and a half to complete.
Please note that it can be difficult to park at the designated spot because a bus stops there in summer. I recommend continuing 300 metres further down Route du Mont Thou, where you can park on the side of the road.

A beautiful walk to discover superb restored drystone shelters.
The route is very accessible but still hilly for those who have a little difficulty walking.
The route crosses many hiking trails, so it is easy to take the wrong path. However, the description is extremely well written and the map is perfect, so be sure to follow them step by step

A lovely mix of meadows, woodlands and heritage sites. No difficulties whatsoever. A pleasant experience. However, even though it's hidden from the roads, you're never far away from them and their noise is (very) omnipresent. Perhaps it's best to choose a day other than a sunny Sunday, when motorbikes and other fast vehicles are out in force, to take this walk...

Great with beautiful drystone shelters. Be sure to follow the app's route carefully, as there are also yellow markings. Otherwise, the directions are correct
impossible to get lost. Start at the wash house, small car park, arrive at the table and no worries about leaving, it's very clear

nice little walk. The path is quite difficult to find after the orientation table, but after that there's no problem. Quite crowded, though

A beautiful, easy and quick walk. However, the directions could be more detailed, especially from the orientation table onwards. There are lots of paths and we took a wrong turn (a 3 km detour). Make sure you take the path in the middle of the field all the way down! The GPX file is very useful for finding your way around.
