Maybe it was the inability to find a parking space anywhere near the town, or the hundreds of tourists disgourging from tour buses and clogging the tiny streets, but I found Les Beux, a medieval fortress and town north of Arles, disappointing.
Once we wandered back into the surrounding countryside, the magic of Provence returned, particularly when viewing the remains of the Roman aqueduct that once provided water to Arles and surveying the surrounding olive groves.
