fishing in south west

[kennard]

hi guys,
new to this...
can anyone tell me or advise me on where some good marks are in cornwall devon area?
for a holiday this year me and my brother want to camp out for a few days and just live off the land and what we catch, hopefully... lol
looking for an area with woodlands close by for firewood and food and somewhere where the coast offers quite deep water for pollock and wrasse etc...
so a long shot but any ideas?
tight lines chris
