Hi, We (2 couples) have booked a 7-day barge trip from Castelnaudery to Port Cassafieres towards the end of September. We then have 4 days before having to catch our flight from Toulouse and are not sure where the best area is to spend this time. We are considering Provence (as long as it's not too far) but are open to any suggestions. We will rent a car. We would love to hear any suggestions you might have.
