Cracker. See Port-Vendres(France)- Llanca for glowing reference!
Look at the map! Drove (hire car :( ) France to Spain so views not as spectacular and difficult to pull in as on wrong side of road. Popular with local bikers , and no wonder up,down, round and around. Not at all bad for a main route from one country to the other. But with all the traffic a route like this brings. Not such a problem on a bike tho'. Wonderous and perfect surface. Keep your wits about you if you are going to get,ahem,pacy! A joy. Its the N260 again innit!
La Seu d'Urgell - Sort section
An unbelievably good road across the pyrenees which runs from quite close to the Andorran border down to the town of Sort. There are many fast open corners with great visibility, allowing you to use road width to the full. This is one of if not the best road I ever rode. A must if you are in the area. The only downside is that sometimes some cattle walk into the road, but this is only a problem on a few of the more blind corners travelling up the mountain at the start of the route.
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.
