Lighthouse Ledge - Florida Keys
Lighthouse Ledge offers a typical Keys reef dive, generally quite shallow and suitable for newer divers. You'll find scattered coral heads and plenty of smaller reef fish darting between them. It’s a good spot to get your fins wet and ease into the local diving scene without facing strong currents or deep profiles. Expect to see grunts, snapper, and the occasional parrotfish grazing the algae.
