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.
I use the roads in this route alot myself and can agree its a great route. Buttertubs Pass is fairly well known as Top Gears Clarkson often raves about it being his favourite road in the UK. For those who dont know thats the road running south from the B6270 into Hawes village. Whilst there, stop for a brew at the Penny Garth cafe - often mentioned in the Bike magazine as its on their 440 test route.
