Personally I would GOOGLE camping in Cornwall & look at the websites for the various places. There is nowhere actually in Newquay so all will need see you driving if your old enough or getting public transport into Newquay itself.
Though some sights do provide transportation at times.
As locals we don't stay there ourselves so can't help.
Also use the forums search facility to see what others have said about other campsites etc.
Welcome to the forum ... & its accommodation
