I rode this road for the first time in the Summer of 2009 and it is a great road, lots of twisty bits, good surface although there were some road repairs going on when I rode it and new bits of road being added. The best bit is the fantastic scenery and the fact you don have to really attack the road to enjoy it. It is as good to ride at a touring pace as really going for it. Traffic was light and easily disposed of and there are places to stop and rest.
Agree this is a fantastic route - worth detouring a considerable distance to do, or even planning your route around this particular stretch. Amazing scenery, blissful road - and if you are a bit of a city biker that rarely does the twisties at home, then its one of those roads where you may wish youd been out with your local police bike instructors for a refresher in order to maximise enjoyment of this once. Top class.
Its been a while since I was last there, but this road is exceptional! Great scenery and some fabulous hairpins up and over the centre section. Some fast straights towards the end.
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.
