Description of the walk

First of all, please have an IGN map or GPS with you before taking this trail. Indeed, this trail is made up of paths marked Red and Blue, then unmarked, then Yellow...

(S/E) Start from the Arcenant village hall car park, Rue de Beaune. Follow this street up to the village, turn left at the junction, then left into Chemin de la Source. Follow this quiet path alongside the Raccordon stream.

(1) Take the path on your right between the trees, marked Blue and Pink and called "Sentier Voituret". Be careful not to take the wrong path here, as there are many possible paths leading from this clearing to a small "clearing" where the Doua fountain is located.

(2) After about 500m, you'll climb up a path on your right (marked Blue and Pink), you'll arrive above the cliffs, continue to the Trou du Duc, still following the signs. The entrance to the Trou du Duc is not clearly visible; as you approach the cliffs, you'll see the small platform which, by lifting the plate, will allow you to descend into the Trou du Duc cave (optional). The hole is on your left, just before you leave the cliffs. The view is magnificent.

(3) Then follow the blue and pink path down into the valley to a crossroads.

(4) Leave the markings and take the left-hand path (where there's a cross).
The path then climbs a little for about 500m, follow the main path, you'll come to a junction - you should always be taking the main path (the one that goes off slightly to the left). Pass a bend to the left, then one to the right, and follow along the forest and a clearing.

(5) At the end of this clearing, turn right, then immediately after, at the crossroads where you'll find the GR®, take the left-hand path (be very careful here, don't follow the GR®). You then continue on the main path, taking neither the right nor the left-hand paths at the next junctions (look carefully on your map at this point for the right path). The Gallo-Roman site will be signposted after a while (approx. 1km).

(6) Follow the signs to the left. Take a break at this archaeological site.

(7) Then take the path at the bottom of the Gallo-Roman site on the right, and follow it in the direction of the Maquis, which is signposted at the beginning. Even if the Maquis is no longer signposted (damaged sign?), follow the path back down into the valley to the foot of the Maquis.
Then continue on the same path up the valley.

(8) At the top, take the first well-marked path on your left. At the next crossroads, several paths are indicated. Take the one on the right and follow it.

(9) At the next crossroads, turn left and you'll come to the viewpoint indicator. Follow this white path back to the village on Rue du Vieux Puits. At the end, turn right and then right again to reach the car park. (S/E)

Yes, it really is a lovely walk with stunning views, points of interest along the way and… some steep climbs.
We found the ‘Tru du Duc’ easily, but, given our age and our fear of heights, we didn’t go down into it.
Thanks for the warning: the GPS was very useful, and above all, thank you for this lovely route

This route offers some interesting sights at the start and end of the walk, as well as beautiful views. The section leading to the trapdoor and ladder that takes you down the cliff to see the rock cavity is not immediately visible. Don't miss the viewpoint at the top of the cliffs.
Thank you for this wonderful discovery.

A very beautiful hike with stunning views of the forest and its autumn colours. Quite steep but short climbs at the start and after the maquis site. I had to use the app at one point because the description was insufficient.
In any case, thank you for this hike suggestion 😃

A very beautiful hike with no difficulty, except perhaps the very steep slope at point 2 over approximately 300 metres. There is a second, less steep slope at point 7, which can be bypassed. At the fork, instead of turning left to descend to point 7, continue straight ahead. This hike should not be attempted in wet weather or if it has rained the day before, as it will be extremely slippery. Lots of viewpoints and interesting things to see! Trou du Duc (cave), Gallo-Roman site, maquis...
A must-do hike in this area

A beautiful hike with superb views. Accessible to all. The only difficulty is from point 2 onwards, with a very steep climb of around 300 metres. After that, it's relatively flat and pleasant. Because of this steep slope, the hike is not recommended in wet weather or if it has rained the day before, as it will be extremely slippery. The hike is very interesting (the cave - the Duke's Hole), the Gallo-Roman site, the scrubland and its history. At point 7, there is a second slope that is less steep and shorter, which can be bypassed. Just go straight ahead at the fork instead of going down to the left towards point 7. The second part of the hike is mainly in the forest. Very pleasant.
A must-do hike in the area ☺️

Very nice walk,
Lots of shady areas on this route, punctuated by remarkable points to discover. The water stops added a touch of freshness and the refreshment points were much appreciated by our 🐕‍🦺.
We did this walk as a family with our 12-year-old daughter without any problems.
I'd recommend it (GPS tracking of the route on the app is essential, in my opinion).

A fine route I completed on Sunday 12 March with my 10-year-old son.
A few technical sections (uneven + slippery ground) but still manageable.
There were quite a few trees in the way, which you had to pass over, under or around whenever possible.
The duke's hole is just impossible to miss! Impressive and ... vertiginous.
The other points of interest (Gallo-Roman ruins, scrubland) mean that the walk is not monotonous.

A pretty, shady and varied walk, with many points of interest (landscapes, geology, archaeology and history...). A few passages towards the Trou du Duc require attention, particularly with children, but nothing is really challenging, at least in dry weather. After the Monument du Maquis, the route is less interesting, especially as the viewpoint over the village is almost non-existent now that the trees have grown over: so, if you're reluctant to tackle the climb after the Maquis, you can head back down to the village via the Puits Groseille and the source de la Doua. But this shortens the route a little...

A pleasant, shady walk. Most of the route is in woodland. No viewpoints or surprising places apart from the trou du duc, which provides a little diversion. Suitable if you feel like walking in the forest.

A pleasant walk in dry weather. A steep climb of 500m before the cliffs and another slightly steep climb after the Maquis, just take your time.
Trou du Duc well signposted, nice viewpoint. Not a very popular walk. Can be done with a medium-sized dog without difficulty.
