Hello Wigan,
about . . . .
'been on the website,but nothing to read about camping arrangements'

On the opening page of their website it says....

'Thursday evening. We can now offer camping on Thursday night at our campsite at Knotford Nook (the same as last year). The campsite will be equipped with toilets, washing facilities, catering outlet and security, showers will be available from the football club (over the road), see notice boards for shower times.'

...and on the order form on the booking page it says....

'Camping - Outdoor only. Please state if tent or caravan/ camper @ £4 per person per night'

If that isn't enough for you - there's an email address there to contact 'em with your enquiries. Cheerio then, HFA
