You'll be in an interesting bit of France, not for tight twisties or Alpine views but because it is dead flat and as such totally different to anywhere else. It gets VERY hot at the height of summer but so does the rest of Provence. The roads in and out can get busy with traffic, camper vans and the like.... You'll not be the only bod looking to go there! Just relax and take it for what it is, you are on holiday after all.
Arles is a nice town and there is a great beach at Saintes-Maries-de-la-Mer. Follow the D38 road out of Ste Maries, westwards, past the harbour. You'll see lots of cars parked (parking is free) facing the sea.
This is near enough where I mean.

Find a slot, though it does get busy space wise. We used to go a lot when my parents lived near Apt in the Luberon, Provence. We aimed to get to the beach for around 10:00, set up on the beach, have a coffee, have a swim, have lunch, have a swim again and leave at around 15:30, stopping at one of the free public showers to wash the sand and salt off. You'll be lucky (or unlucky) to find any Brit's on the beach, which is a bonus. The locals who use it are all civilised. There are some cafes that let out sun beds. We never bothered but did bring a sunshade. One of those cheap chuck away half tents is good.... but you'll need to pin it down when the breeze springs up in the afternoon. The church is worth a quick look if you fancy it. It's dedicated to the Black Madonna and is of some significance to the locals. Bull fights (unlike the Spanish, the bull in not killed) are another local passion.
The boat cruises up the Rhone delta are quite nice as you'll see the bulls, horses and birdlife.
Aigues-Mortes, is a decent place, too.
The local tourist offices are very helpful.

or a Google of Camargue will turn up most of the guff..... Which she is on the case with, I see. A lady after my own heart!

PS I can never fault the Michelin Green Guides. Their guide to Provence is no exception.
