Great road along the side of a lake, you can make it to Jaca from Bilbao in a day which is a good place to explore the pyrenees from.
Fantastic scenery, and the highest pass in Austria. Open May to November. Can be busy - so probably best to avoid at weekends. Very popular with bikers, but cars too. You need a head for heights and have to like hairpins too. Some nice fast stretches too. Very few hazards except the road itself: the 29 hairpin bends. Visibility is good though, and there are hardly any side roads. Jusat watch out for people gawping at the scenery. 360 views from the Edelweissspitze - stop for food and a beer there as well. It is a toll road though. Euro 17 for a day/ Euro 30 for a 30 day pass. Their stated aim is to be the most biker friendly pass in the Alps! More info here www.grossglockner.at
This road is a peach it starts off with fast open sweepers that occasionally tighten up, lots of scenery, you then hit the uphill section, twisty, great views, across the cols, then boom when you hit spain the road surface changes and it is like a rollercoaster, fast sweepers and tight bends follow one another in quick succesion, there is bound to be at least one downhill bend which tightens up when least expected giving the brakes as well as your heart a real workout. You then pass through a tunnel and it becomes very fast dual carriageway with sweeping downhill bends that seem to go on forever at many points it is difficult to know if you are going up or down until you try to stop.
Absolutely stunning piece of road - one of the best I've ridden anywhere in Europe. Classis mountain twisties, smooth tarmac, no traffic. It's hard to pick out one stretch of the N260/N152 route across the pyrenees as being the'best', but this is probably my favourite of the lot. You can really open up a big sports bike along here, but make sure your brakes are up to the job - they'll take a real hammering on the downhills.
