If you don't have a car, Barcelona will be too far.
Around the Pyrenees area there are wonderful places, like the Nuria valley (near Pigcerda, in the border), where a ride in a rack train will lift you to a 2000m valley with a sanctuary home of the virgin of Nuria.
It's an alpine scennery just under the shadow of the mighty Puigmal peak (just under 3000m)
