I returned to Saint-Rémy and the tourist information had opened. I bought a map, checked the time tables, and learnt that the bus from Les Baux I had considered was summer-only. By now, the last bus back to Arles had gone. Instead I had to jump on a northward bus to Avignon to take the train back to Arles. Once I was in Avignon, there was no reason not to take a quick look at that city. Avignon is a bigger city than Arles and boasts quite a few sights. The old city wall is intact, and this is one of the gates.
