The N-145/N-260/C13 from Andorra to the Port de la Bonaigua is a super drive (best driven south to north). This then links to the D918 Route de Pyrenees which takes you over the Col du Portillon, Col de Peyresourde, Col d'Aspin, Col du Tourmalet, Col du Soulor, Col d'Aubisque and Col du Pourtalet.

Of the Alpine and Pyrenean passes, the Port de la Bonaigua. is the the most memorable.
