Thought I better give some info for others.
Right next to Newquay is the Gannel river esturary with trout and sea trout, free fishing up to Trevemper bridge, not sure above but I can fish a couple of bits that my mate owns.
St.Mawgan and Mawgan Porth have the Menalhyl river with tickets (cheep) from the Merrymoor Inn at Mawgan Porth
Further afield theres the Camel and Fowey rivers, more for salmon and sea trout
Check out the angling 2000 web site for more ideas.
