I will be making a one day drive from Bordeaux to Barcelona on Saturday, April 7. Planning to use A61 to Carcassone. Will stop there in late morning, leaving around 1300 -1400 for Barcelona. I'm wondering what experience others might have in driving south from Carcassonne to Perpignan via Limoux? Is this a reasonable option or is it best to continue along A61 to Narbonne then head south?
