More or less what Minstrel says, I would add that there are several places along the Camel Trail from Wadebridge to Padstow where you can access the Camel, you will have a fair to middling chance of catching the odd Bream , or maybe a Bass. Its a bit early for Bream, but you never know .
At Wadebridge itself, the river is full of Mullet, some are very big indeed. You can get to the river above the Bridge on Wool , but I am not sure if the access is controlled by the local Angling club . You will need the tide to be at almost full flood to get the best out of it but the Mullett are there most of the time
As you walk along the Camel Trail from Wadebridge,toward Padstow, about halfway along on the left there is a tidal dam near to the old quarry workings. The dam is full of Mullett . I have had them from there on small mepps spinners with either a rag or lugworm on a hook trailed about 6 inches behind the lure blade. They are great fun, but very frustrating , you can watch them follow the lure then back away at the last minute.Ideal if you are packing a spinning rod.
If you plan fishing the Camel , then it is easy to hire a cycle in Wadebridge and do the trail that way , you can scope the river out and it wont take you long to get to the fishing spots .
St Tudy is a few miles from Wadebridge, if you were fancying somewhere different, you could go across to Port Isaac, at half to high tide you can fish into the inlet there using a float , fish from either side of the inlet on the sea side from the harbour wall, there is a blowhole on the right as you look out to see, I have had some good Wrasse from around there on float fished frozen sandeel.
I think you will probably have enough ground to cover there with mine and Minstrels ramblings .
Good Luck.
