We have just returned from a week away at Tredegar house. The site is located just off of the M4 and we had read many reviews about the traffic noise- we found this to be minimal and did not disrupt us at all so don't worry about that! The site is great, not too big and excellently located within easy reach to Newport and Cardiff. We rode our bikes into Newport one evening for drinks which is easy enough to do. We took our 2 dogs with us and having the large grounds of Tredegar house on the doorstep was excellent. These can be used for free by the general public and they are great for dog walks. Now my couple of criticisms: no tv aerial points which is poor- the caravan club really should have these as standard on all their sites now. The male shower block only has 4 showers which is not sufficient for a site this big, this was made worse with one of the showers closed for maintenance all week meaning only 3 shower cubicles. These small criticisms aside, the site is great and we would visit again.
