Description of the walk

Park in the village square in Marnans.

(S/E) Head east on Chemin de l'Abbaye, with Olagne on your left. Then take a steep path that climbs to the hamlet of Les Clercs (pretty adobe houses).

(1) When you reach the hamlet, take the road on the right and almost immediately take a path on the left and climb steeply along a villa fence. Take the road that climbs to the right, veering south, until you are about a hundred metres before the water tower. Turn left onto the track to the Étang des Mermes (herons, ducks, reed beds).

(2) Go around the pond on the right (you can walk along the dyke only). On the other side, take the path on the right at the end of the dyke and you will soon find the "Combe des Mermes" sign in the woods.

(3) Take the path on the left, going straight ahead at first, then turning left at a fork and continuing straight ahead until you reach a T-junction, where you turn right. Cross two valleys via small wooden bridges and cross a small stream. Climb up the other side and turn left towards the north-west.

(4) Immediately afterwards, walk along a small private pond (ducks) on your left. Climb up a path of large stones that descends slightly in a bend to cross a valley and climbs back up through the woods to the hamlet of Gros Jean, ignoring two paths on the left, a path on the right (towards a few houses; Le Martinon), then two more paths on the left (the first of which is marked in yellow).

(5) At the hamlet of Gros Jean, at the crossroads, descend to Marmans (S/E) via the small road that branches off to the left (south-east) then, at the T-junction, take the hairpin bend to the right (west-south-west).

A very pleasant walk through valleys, woods and ponds. The church in Marnans is also worth a visit!
⚠️ Be careful on the steep and sometimes slippery paths in the forest between the two ponds.

A lovely walk starting from the magnificent Priory. Beautiful descents in the clay... (be careful!)

The route is incorrect at the end between the two ponds. Continue straight ahead, following the yellow markings to reach the second lake. This section is uneven.

A very beautiful, pleasant and enjoyable hike
Many passages through the undergrowth
However, take care on the descents between 3 and 4, as they can sometimes be dangerous. Lots of pebbles, so quite slippery even in very dry weather

Between points 3 and 5, there are a few tricky sections (stony slopes) which can be very slippery in wet weather, as they are already difficult in dry conditions.

Unfortunately, it was foggy and muddy, but we still had a great time... we'll do it again to see the promised panoramic views of the VERCORS!

Thank you, jhelbe, for this information about the markings that should not be followed, which I have included in the description.

A nice, varied walk. Lots of undergrowth and shade. A easy route, but be careful on the fairly steep descents where the ground is sandy with small and large round pebbles, which can be quite slippery (for someone approaching seventy like me!). I think walking shoes are better than trainers for this walk.
Also, take the time to read and look at the map to avoid mistakes. My wife was very helpful as my co-pilot!
One thing to note: on the path from Martinon to Grand Champ, there is a yellow marker indicating that you should turn right at a certain point. On the map, this path branches off to the right at the word "Champ" and leads to "Les Grilles". It is marked in black. In fact, you need to turn left to reach Gros Jean, following the red line on the map. The smartphone app helped us to take the right route!

Impossible to find the way with the description as indicated, but from the start between the two ponds. At 1, turn left and not right as stated in the instructions. I didn't do it, I'll do it again next time... thanks anyway. Too bad you couldn't do this walk. Thanks again.

I have sent the actual route as a suggested hike.
If there is another way to proceed, please let me know.

and not a new trail, because I stubbornly followed the trail marked through woods and ravines! Not recommended at all...

Thank you for your feedback. Have you found a new GPS track that we could use instead of the current one?
Kind regards

The recorded route is simply incorrect and corresponds to a path that does not exist between the two ponds! PLEASE NOTE: do not just follow the route on your GPS; the description is a little less imprecise....

Thank you for these clarifications, which I have just added to the description. The author has not been in touch for some time.

Hello,

I found my predecessors to be rather harsh in their description of this walk. Unfortunately, I have to agree with them. The description is often far too brief, leaving plenty of room for error. What's more, there are some inaccuracies:
- At the hamlet of Les Clercs, you have to take the road on the right and almost immediately take a path on the left.
- At the Mermes pond, take the path on the right at the end of the dyke and shortly afterwards, in the woods, you will find the Combe des Mermes sign.
There is also an error in the route through Combe des Mermes. When the author wants us to turn left off the initial path, there is no path on the left. You have to continue straight ahead as indicated on the IGN map (it is true that on the ground, the path has nothing to do with the straight line shown on the map).

Nevertheless, it is a lovely walk, and I would like to thank the author for introducing me to it.
And with the Visorando app on your smartphone, you can easily find your way back... (just saying...).

Happy walking!

Yannick
