This aire keeps changing, it used to have a real person whom you paid, then it went to a barrier and credit card, which didn't work much, so they left it open. They also used to have a small free bus into the city, but it seems no longer to run at all. However, it is still a great aire to stop, not free, but it is convenient if you wish to visit the city and the market is great. Several buildings etc., to go in. We like it and it is convenient for Carrefour http://www.i-campingcar.fr/aires.php?ville=NARBONNE
