We will be in Arles May 17 (1/2 day), 18, and 19. The 17th will be spent exploring Arles. The 18th we will be on an all day wine tour that includes Pont du Gard, leaving and returning to Avignon. Then we will explore Avignon and eat dinner there. The 19th I was hoping to see Aix-en-Provence and Isla Sur la Torgue if possible. What is the best way to get to each of these towns from Arles? Maybe its better to go to Avignon to make connections?
I don't really know what is in these towns to see, just heard they were charming and nice. Are they worth seeing or is one more interesting then the other? If not, we have an extra day in Arles to do something fun, any suggestions?
