Hello Pierre, Following on from your message about this walk, it’s true that without signposts it’s not easy to find your way.
It’s a walk I did with my group and recorded the route on my smartphone whilst there, so there are no mistakes. Anyone who hasn’t recorded the walk on their mobile will find it a bit of a struggle. There are lots of narrow streets and paths that aren’t very visible, and above all, there are no signposts. I’ll make a few minor adjustments to numbers 13–14 and 17–19, except for path no. 21 – you do need to be careful there, but it is definitely there.
Kind regards
and all the best on Visorando
Yvon

Between 13 and 14, I ended up too far down Rue du Puits Cornier; when you’re on the path to Haut Val, you have to turn left at one point – this isn’t signposted.
Between 15 and 16, I couldn’t find the Les Platieres path and was forced to walk along a road that was dangerous for pedestrians.
There were no signposts between points 18 and 19, so I lost my way on the walk – with paths branching off to the right and left at the junctions… I never realised I was meant to turn left before the A15; I didn’t take the right path, so I eventually found the main road further on.
I also missed the path at point 21 and found myself on the outskirts of Montigny-les-Cormeilles…
I gave up following the route and took the shortest way back to Cormeilles station – a rather tough day’s walk
A shame, as there’s a magnificent view over Paris and La Défense from the Butte d’Orgemont and the Butte des Chataigniers.
