French Coast to Canal du Midi

We passed through the town of Ventenac-en-Minervois. They have a wine cellar and museum, markets on Wednesdays and a small restaurant. The Chateau de Ventenac is the dominant feature in the town. How do we know all this? You buy the essential book, Canal du Midi Waterways Guide, before you leave and that is your 'bible' for the trip!
