Visas & entry
A slow-travel guide to Carcassonne's medieval citadel describes summer crowds pouring through the old walls with tour buses unloading in force, turning the narrow streets into more of a queue than a walk during peak hours. Their advice: visit between 7 and 8am before the buses arrive, or after sunset once the crowds thin, and for a genuinely different, quieter side of the city, cross the Aude River to La Bastide Saint-Louis, the lower town most day-trippers skip entirely.
