Most of the immediate flats north of the airport are going to be too shallow, even in a kayak. The flats to the west of the canals/airport before Pelone Islands are good for floating. Continuing west to East Flats is another option or a slight north to Little Flats as well. I've had better luck in the Spring and Fall.
