When planning our journey Arles was one of the places Wk said he wanted to visit. Initially we (or more like I) would have absolutely loved to visit the lavender farms in Provence (all thanks to L'occitanne, I'm sure 99% of girls who look at L'occitanne have dreamed about visiting Provence!) but because it was winter, there would not be anything to see as the lavender will be all grey and dry, and the farms would not be opened :(
When we planned our journey we were driving towards the south and we had to pick a place to stop at otherwise it will be a long, hellish drive. Since Arles is in Provence and Wk wanted to visit, to Arles we went.
