Thanks Peachy for recommending Pont Kemys It really was a lovely campsite with fab loos and showers. We were in the tent field and it was lovely and quiet. Didn't really like the Chainbridge pub - it had a vastly overcrowded camping field attached to it and wasn't very clean so we walked up to the Black Bear a couple of nights. They were so friendly in there and gorgeous food.
Can also recommend the cuckoo and goose pub a few miles away in the middle of nowhere - very basic food but all cooked on an aga and really really delicious. decor was like out of the 1920s!
Did have a slight problem with the weather and our poor old tent but hey ho
