High granite slab that you find when surrounding the Valmayor reservoir when the water level is high. If you do it clockwise you will have to unclimb it, it is advisable to be accompanied to be able to lower the bike safely. If you do the route counterclockwise it will be more complicated to climb it. The slab is very smooth and has few grip points.
