Park at the entrance to Morignole which is balise 287 and then on the right climb through the village before crossing the bridge and turning right.
The path is narrow and faces southeast making it a nice winter walk as it’s quite sunny. In some places dead trees had fallen across the path. There seemed to be a lot of dead trees as well as pines, machia and thorny bushes. The thorn bushes had planted themselves right on the path in many cases and were particularly malevolent. Long pants obligatory and long sleeves desirable. A pair of hedge clippers would come in handy.
It took about an hour to reach this balise. Mostly the path was schist, climbing steadily and not too steeply.
After the marker, the path was grassy with even more thorn bushes. It climbed a little more steeply but the views were great.
The reward was this spot which I reached after about 2 hours. There were no real picnic places until the giant rock slab here. I never did get to Balise 290. I estimate this at least 350m dénivilé.
