We went to Camping Le Ranc Davaine in St Alban Ardeche in mid June for 11 nights . We (husband and two boys 6yrs and 3yrs) went on the euro tunnel to calais and it then took about 12 hours to drive to this campsite.
Campsite was great, the keycamp courier Rachel was excellent, very efficient. The mobile home was spotless and it was the cleanest mobile home we have stayed in. The site is medium and there is a large pool complex which is great but not that toddler friendly. As it was low season there wasn't any life guards. My kids loved the slides although in high seasons they would be really busy. Weather was very hot in the 90's. There is a restaraunt on site and also a taking away place. The food shop was open in the mornings only but again this was because it was low season. The supermarket was only about 10 mins drive away.
A great holiday and excellent value, keycamp cost was £450 plus £500 for travel & food.
