Not a lot of shallow water coral around here. We're cursed with the world's most beautiful white sand beaches, and the sand goes all the way out. The closest decent natural bottom area with coral is the Dutch Banks, about8-9 miles to the south west in about 75 feet of water.
The Destin jetties are a nice place to snorkel that you canreach by land if you just want to see some cool things and pretty fish, 5 to 30' deep. Not coral, but clear water and lots of life on those rocks.
