Barcelona via Andorra to Toulouse, 7-Day Cross-Border Trip

Cross the Pyrenees from the Mediterranean, drive through Andorra to the Carcassonne fortress, then reach the Rose City of Toulouse.

A one-way self-drive linking Spain, Andorra, and France. Spend two days in Barcelona taking in Gaudí, two nights in Andorra for its lakes and hot springs, then cross the Envalira Pass and head via Foix to Carcassonne, finishing in Toulouse. Each driving leg takes about three hours, with overnight stops in between as buffers. Suited to first-time visitors who want to see several countries in one trip. The trade-off is seeing only the highlights of each place, and you'll need to return the rental car in a different city.

In winter, the Envalira Pass may close without notice. Snow tires or chains are required, and the tunnel is an alternative route.
