San Sebastián to Aosta Road Trip: Ultimate Guide

The drive from San Sebastián to Aosta covers roughly 1,200 kilometers, crossing the Pyrenees, the French Riviera, and the Alps. This route (A-63, A-64, A-9, A-8, A-5) takes about 12-14 hours of pure driving, but plan for two to three days to truly experience it. A little-known fact: the section of the A-8 near Nice was originally built by the Romans, and remnants of the Via Julia Augusta are visible just off the highway.

Fatigue management: use rest areas every 2 hours (examples: Aire de l'Adour, Aire du Var).
