Contrary to the reviews I have just read we intend to visit again and stay longer.  Totally underestimated what there was to see.  The site was clean.  Perhaps worth remembering that this site is on the edge of a city - it is not a idyllic rural retreat.  Place for both in the club network. Guess site was a bit noisy but it was Saturday night and there were children away for the weekend.  Seemed like a site layout problem that was causing escaping balls.  There is a big green area with vans around and the big green area had room for ball games - it happens. Not necessarily Durham specific - just wish parents wouldn't forget that they came with children and need to keep an eye on them especially when they play on a vehicle access area. Maybe avoid the weekend or school holidays but the site is worth the visit.
