Excellent site, well run and clean, weather was kind to us so made stay more enjoyable, only downside is if you are pitched at top end of site there is a bit of traffic noise, but you get used to it. Word of caution, be aware that the National Trust lock their gates at 9pm, we went out for a meal and found the gate locked, silly me, didn't realize there was a additional key on the fob, slight panic in till a car came out and explained the procedure, not fault of site but could of been avoided if they had given us the site handout, didn't seem important until then. Just be aware the Tredegar House is completely covered in scaffold at the moment so is not looking at its best but is still worth a visit.
