We were very dissappoointed when visiting Les Baux de Provence on a recent trip to Provence. You have to park at the foot of the hill and street parking costs 4 euros (flat rate). The thing is you have to pay only with coins (no credit cards accepted at the meters) and there is NOWHERE to change bills (no kiosks or shops). So we had to turn round and resign not visiting the village, as we didn't want to get towed or fined. So, better take 4 euros in coins with you when you go!
