I notice a lot of people search the Internet for vineyards really close to Carcassonne.
If you want to do a full tour of a vineyard and winery near Carcassonne, I naturally recommend visiting me at O’Vineyards. We’re less than fifteen minutes away from the castle (by car). And perhaps you’ll have time to visit a few other vineyards near Carcassonne.
If you just want to see some vines near the castle and take some really pretty pictures, then there are actually vines right next to the medieval cité de Carcassonne. My friend has a vineyard directly outside of the castle.

He doesn’t really do tours or opening hours, but if you just want to see some vines while you’re in Carcassonne then you should visit his vineyard.
