Hi Kevj84
My husband and I stayed at Gwithian Farm near St Ives (5 miles)
http://www.gwithianfarm.co.uk/
This is a brilliant site although no big play area for the kids has enclosed garden with sand pit, table tennis and pets corner but pitches area good size, if you walk to the top of the site and walk across the sand dunes then down onto the beach which is very safe, used by can surf body board etc, but also safe for playing as no major under current. If you choose not to go onto the beach you can explore the dunes there are three/four cafe's to take a rest and if you turn right as you walk onto the dunes and about 30 minute walk away you have a National Trust area where you can watch Seals playing in the water and lounging on the beach.
We loved this site it was clean and well run, toilet block has the normal showers etc, but has separate shower for wet suits, plus family bathroom etc., all kept very clean, the staff are very helpful too! little shop on site which has croissants & pastries delivered twice a week, fish & chip van once a week and fresh fish van once a week. Very friendly pub just across the road with village shop next door.
When I was looking for somewhere to site did put a post on forum, but also email the three sites in the area with specific questions and Gwithian replied within a couple of hours not only answering my questions but giving me more information and this was a Sunday.
All in all lovely site, and you can tell how much we loved it we have already booked to stay again next year and that is a first for us in all our years of caravanning. That’s not saying we haven’t enjoyed any other sites but think it was good in every way.
Hope this helps
