This is the Tidelands launch area. Park next to the grass and wheel your kayak along the hard surface walkways and launch down by the dinghy's.

It's easy access and ample free parking, close to the bridge, safe, and an easy launch area. If you go early you can park under a tree for shade.
If you surf around you will find information on nearby clam beds, patches of eel grass and their boundaries, a variety of structures that draw fish, you are close to fishing the channel and you can head out in multiple directions for different kinds of fishing. Conditions are always changing, so what you target should change as easily.
In my own humble opinion, as you go further into Glorietta Bay toward the launch areas and boat docks there, what you will tend to catch are small bass. Other people may have other advice about this. The main difference is convenience and kayak travel time for finding fishing areas that might be more productive.
If others disagree with my assessment, I would like to hear their opinions too.
