When it comes to finding schools of kingfish, the local knowledge of a guide can simplify things. But if you are on your own and know the fish are in the area, it’s crucial to isolate the structure that holds kings, like oil rigs in the Gulf, a reef line or a small piece of artificial reef. Anywhere you have long stretches of flat, featureless bottom followed by rock piles or some other structure where baitfish are likely to congregate is a good place to try for kings. The structure does not have to be sizable — even a small bump on the bottom can hold fish. I can think of one particular spot in the Keys where a friend and I have caught loads of kings, and the structure is nothing more than an engine block in about 30 feet of water.
