There's probably 6-10 different marks from north row ends(the old car park) down to the wherry beach in the south. If you have a walk along the cliffs you can see the flattened areas of grass where the most commonly fished ones are. The cliffs straight out the back of the lighthouse have 5 within 100 yards but please be careful as some of them are crumbling and slippy when wet.
Fish the point from the back into the bay to the south when the sea is from the north.
Just read the sea angler link, please don't use 3/0 hooks if you are targeting big cod, go for 8/0 at least you will stand a chance of landing the big un!
