I'm interested in going to visit wineries in Châteauneuf-du-Pape. Is renting a car the only option? Is there a bus or train service from Avignon ? Can I rent a bike? Or the area is too large for the bike?
If renting a car is the only option, would a U.S. driver's license work? Do I need to get an international driving permit from AAA? And about how much should I budget for renting a car for a day?
