It's name sound like a poem or a music. Walk trough it's streets, sit at its cafe, eat at its tables, visit its Arene, Amphiteatre, museum and gardens or window shop in its boutiques and you'll be sure! At the Voltaire square, you'll see the cafe (now called Van Gogh Cafe) that inspire a beautifull paint to Van Gogh (among others). Animation in the center of the square and the tables of all the cafes that meets under the trees will complete the picture!
Visit the Arena of Arles. The Arena and the Ampitheatre are what is left of ancient Arles. The Arena is intact and still used for horseraces and the Amphitheatre is still used for theatre and operas.
I am going to guess what you are thinking now...no no not that Arena again...is there nothing else to see? Yes!
Here is my brother standing on the Arena. The Arena is very high, don't underestimate it :) It even bigger then your average football/soccerstadion.
The arena use to be used for man fights in the Roman times, but now musicals are held here, horseraces, cattle catch matches etc. etc.
