Why the Florida Keys Offers Some of the Best Snorkeling in the World
Why does everyone rave about the Florida Keys? Simple: it’s the only place in the lower 48 where you’ll find an honest-to-goodness living coral barrier reef right off the coast. That’s no small feat.

The Reefs of the Florida Keys are Unlike Anywhere Else
Check out the reefs and you’ll get the idea fast. These aren’t little patches of coral. Elkhorn shapes twist and branch out like an ancient forest, brain corals resemble, well, giant brains, and neon-colored fish swirl around in a kind of underwater parade. It’s not uncommon to see a sea turtle gliding by or a stingray cruising along a sandy bottom.

No problem, there are still beaches that let you wade right in, with nothing but a mask and snorkel. Whether you’re taking a snorkel trip on a boat, or jumping in solo, these waters play nice with both newbies and old pros. You just show up, take a breath, and jump in—it’s that easy.
