Here, city life meets a world-class dive site where tides from the Atlantic Gulf Stream create a brackish haven for rare marine life. The sandy flats and bridge pilings are alive with tiny nudibranchs, camouflaged frogfish, and delicate seahorses. It's a macro-photographer's paradise, accessible to divers and snorkelers of all levels.
