The site was great, pretty quiet when we were there.
I've cut and pasted the review I did for uk campsite below (it's wuite long)
Just back from a fab 10 night stay at this site in a eurocamp static. Situated on a spit of land near Trinite sur Mer on the southern Brittany coast.
Had a look at the touring pitches and they did look on the smaller side if you have a beast of a tent. Although you could always park the car at the beach carpark next to the shop. The pitches were grassy and well mown with hedging at each side for privacy.
The site was pretty quite considering it was May half term. The statics seemed full but only about 1/4 of the touring pitches were used.
Toilets and showers were very clean every time we went near them - you do need to take your own toilet roll and soap with you each time. The shop was very basic although you could order bread if you wanted for the next day. I expect that it is better stocked in the height of season.
The pool was heated so that our children were happy to play and slightly covered which meant that we could sit and watch them even when it was raining. The beach just outside the campsite was lovely with very clear water. There were a few dead jellyfish around and you would want beach shoes for the rockpooling.
We had one meal at the site restaurant overlooking the beach. The fixed price 3 course meals were very tasty and good value at E18.50 (E9.50 for kids 2 course).
We visited the nearby villages / towns of Trinite and Carnac. Trinite is very pretty but full of yachting bods with prices to match their tastes in the clothes shops. The harbour wall offers excellent crabbing for children but take your own crab lines as they do not sell them in the town.
Going in the opposite direction (towards Carnac plage) is a small SuperU supermarket with petrol that you can only pay for via card. If you keep following the road until you come to the roundabout with the Casino on it, there is the most amazing boulangerie. If offers woodfire oven cooked pizza as well as a huge variety of breads and pastries. Well worth the 10 minute drive for the quality.
The only thing I have marked it down for is on the value for money side. While we got a last minute bargain, the prices at the height of season are steep for tourers. 2A + 2C would pay Euro 50+ a night for a pitch big enough for a family tent with electric during the summer hols.
