start on n111 from logrono, head for soria, drive through huge red rock canyons riojan for forst 30k then up to a dam/lake, smooth, undulating, good corner speeds. half way road sudenly climbs up a mountain with a few 180 degree hairpins up to piste 1750 metres. other side of mountain is a great series of 1 in 2 hill all the way down, steep with hairpins but easy to read. at the bottom of mountain, small garage on right for coffee and recirculate the blood then straight road for 20kms 180mph possible. occasional police this side of mountain. done it every year since 99. seen many biker nationalities at the top and they all agree its ace. its a rare road that tests every aspect of bike control, and at the same time with amazing scenery. in june you go from 2 degrees on summit to 25 degrees at bottom of hill in 15 mins or so. enjoy. dont go too mad on it, ive seen bikers bin it and others go back and redo it the other way-its addictive.
