Had a two night stay here in August. There's no dog walk on site but you have easy access to the grounds of Tredegar House which allows you to give the dog a really nice long walk. No play area on site but there is one in the house grounds. We felt that it was too far from the site to let our son go off and play there by himself though. Good clean shower and toilet block. Conveniently close to M4 but this made the site rather noisy especially noticeable through the night. Great access to Cardiff - we used park and ride. Unfortunately kids hang around the park area when its dark so I didn't feel comfortable walking the dog on an evening.
