My sister will be traveling by train to the area in 2 weeks. She will have about 3 days, them moving on to Italy. She is thinking of staying in Arles, hoping to daytrip to Les Baux and Pont du Gard. Is this possible (by public transit or bike rental) and the best town to stay in? She has a wide variety of interests. Would Nice be a better pick? Avignon? Also looking for affordable lodging that is safe for a young singe woman.
Thank you for the help!!
