Done on top rope, this is the one on the right side of the shark tooth. To make it 5.11b, don't use the crack.
Many people have been walking for years just a couple of feet away from this little chunk of rock without noticing it's there. We you leave the "Cerveau" sector, the last route is "Polaire dure 5.11a". From there, start walking towards "As the pique" sector for about 40 feet until it turns sharp to the left and it starts going up. Right at that point, just look at the triangular shape just above to your right.
