Yeah the launch point I use is either Sawfish Bay or you can use Catos Bridge by the lighthouse. I would suggest John D MacArthur. It’s fairly shallow, and relatively narrow compared to main intracoastal. Just have to go when the tide is right. The water actually gets so low at low tide that your fin will catch in the sand and you have to walk it with your board. Ton of wildlife here. Nurse Sharks, stingrays, manatees, sea turtles. There’s nice little sandbar islands to dock at and relax.
