Just to add a bit more detail to my original review:
Nothing really happens until you get to the first dam and the tunnel section, after this the road comes to life. A pefect blend of corners, visibility, good surface and breathtaking scenary bombard your senses in video game style. Although the surface is not perfect, it somehow comes together as a sublime biking experience.
13 short tunnels through rock in quick succession, a mountain reservoir gives an interesting view. The road then calms down a bit before running along another reservoir and through a 4km tunnel, then down to Vielha. A pretty amazing road in all.
