The fastest route from Paris to Toulouse, 677 km (406 miles) south, is via Limoges on A20, then A62; the journey time is about six hours. If you choose to head south over the Pyrénées to Barcelona, the Tunnel du Puymorens saves half an hour of switchbacks between Hospitalet and Porta; but in good weather—and with time to spare—the drive over the Puymorens Pass is spectacular. Plan on taking three hours between Toulouse and Font-Romeu and another three to Barcelona. The fastest route from Toulouse to Barcelona is the under-three-hour, 391-km (235-mile) drive via Carcassonne and Perpignan on A61 and A9, which becomes AP7 at Le Perthus. A62/A61 slices through the region on its way through Carcassonne to the coast at Narbonne, where A9 heads south to Perpignan. At Toulouse, where A62 becomes A61, various highways fan out in all directions. A9 (La Languedocienne) is the main highway artery that connects Montpellier with Beziers to the south and Nîmes to the north.
