Not so much a mountain pass as a hill pass, but you won't be disappointed.
Set directly next to the bustling city of Barcelona, this
is a secluded stretch of road though a forest hill park.
Very little traffic, with plenty of challenging tight
corners that should see you getting your knee down every turn.
Road surface is good, just watch for the odd patch of gravel hence why Id suggest giving the road a medium paced ride first before giving it the beans!
I never saw any police but with its proximity to the city be wary just in case.
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.
