Hillend in Rhossili Bay; are tales of surly security and litter/crowds that much of an issue?
Just stayed at Hillend this weekend. The security guards were burly but not surly

Basically we were greeted by a big friendly bloke who was very helpful and just asked us to try and be as quiet as possible as we had arrived so late (nearly midnight - not intentionally), which was fair enough.
You pay the same price whether you get hookup or not (we missed out as we arrived late and there was none left). We camped right at the end of the campsite which was nice and quiet. Some of the fields were busier. It seems very popular with surfers so there is a fairly young croud but there was a nice atmosphere on site and it wasn't roudy. Didn't see any litter in our field, but we were in the less busy field.
Facilities were good. Each hookup station had it's own drinking water too.
We were happy with the side although it was pricey given we didn't have hookup (£45 for 2 nights).
Most important thing is you are on the Gower Peninsula and it's beautiful!!
