La mouche (7B/7B+) A hidden treasure

This nice block is to find when from the parking you don't go slightly left into the main area, but right on the road there and follow the bend in the road, in the direction of hale bopp. after a few hundred meters you cross one of the GR's there. just on you're left on the back is this nice. sitstart. it's 23 black. I loved it!
