Tredegar House is a good site although there may be a little road noise. Excellent for visiting South Wales and the easy access/closeness of the motorway means that it is possible to visit places a little further afield quite easily. The M4 'corridor' does, however get very busy. There is an Asda very close to the site, which makes shopping easy, and the site is located within the grounds of Tredegar House National Trust property, which means there is plenty of 'parkland' to use. The site is very well kept (as usual for Caravan Club sites) and is definitely worth a visit,
