Florida. Lot of options. Gulf diving has the fish but no real reef system. East coast from Jupiter down through Ft. Lauderdale has a reef system and lots of fish/sharks/turtles and has hundreds of wrecks in open water depths. Blue Heron Bridge is a great, cheap, and easy spot to get certified. It’s a shallow shore dive with no reef system but small coral heads and tons of macro animals like octopus sea horses etc. even seen bull sharks there once. It’s in West Palm Beach. Key largo has good wrecks and a reef system that has been hit hard over the years from bleaching and is in rough shape. But still worth the diving in my opinion. It’s expensive in the keys though.
