If you are in town for a weekend or even a week you won't need a car to keep yourself entertained. Everywhere in the town and cite is within walking distance. Renting a bike and cycling along the Canal du Midi is a great way to safely explore some of the hinterland and local villages. There are shuttle buses in operation during peak tourist seasons. There is a taxi rank at the end of the street and there are regular bus services with Agglobus for local towns and suburbs. The trains go west to Toulouse, east to Narbonne and south into the Pyrenees. If you do rent a car it allows you to explore the Montagne Noire to the north plus all of the amazing, beautiful & historic towns in the local region such as Mirepoix, Lagrasse, Rennes le Chateau.
