Gwern Gof Uchaf. Showers are free and reasonably clean.
think it has gone up to £6 per night now
Toilet facilities are limited - havent used the ladies so I cant speak for that
Bank holiday do tend to get very busy and you cant book. There is a likelyhood that you go to sleep with plenty of space around you, wake up finding guys (I mean guy lines - but you could be that lucky) across your guys - it does happen.
If you get there early enough on the Friday then there are some cracking little spots to the left of the entrance road, near a little outcrop or by the stream which are quieter. You can also have open fires
Oh, it can be a little damp at times.
