Scuba diver exploring vibrant coral reef underwater.

Diving & Snorkeling

Dip beneath the surface and meet The Florida Keys’ wild side. Here you’ll find the continental United States’ only living-coral barrier reef—shallow gardens for snorkelers, dramatic reefs and historic wrecks for divers. Expect clear, turquoise water, colorful schools of reef fish, and the occasional sea turtle cruising by like it owns the place. Whether you’re booking a guided trip or heading out from shore, outfitters across the Keys make it easy to gear up, learn the basics, and go. Fins on, worries off.
