We recently spent 5 nights here and pitched amongst the trees in the upper part of the site (despite some reviews mentioning that noise from a nearby factory was more noticeable in this part of the site).  Yes, there were times when you could hear a few distant sounds and no, it wasn't an issue as it was only audible for a short while while the air was very still).  The facilities were all that we required and were warm and spotlessly clean.  The wardens kept a low profile and Just got on with the job of running an excellent site.  Despite other reviewers comments we were able to receive a generous number of TV stations as well as reasonable mobile phone coverage and 3G internet, so it clearly depends on where about on the site you are.  We will definately return to this one in the near future.
