We have really enjoyed our snorkeling Florida Keys experiences, and have snorkeled all over, including Key Largo, Key West, and all the keys between that we call the Middle Keys. The keys have the third longest barrier reef in the world, and the only tropical coral reefs in the contiguous states.

We were very pleasantly surprised by how fantastic the snorkeling is in the keys. The reefs in some areas are the healthiest we have ever seen, and are packed with life. Another surprise was that the best Florida Keys snorkeling spots are not where we expected them to be.
It is worth noting that nearly all the snorkeling in the keys is by boat. There is virtually no beach or shore access snorkeling, with a few exceptions in both Pennekamp and Bahia Honda parks (both very poor shore snorkeling spots). That is because the healthy reefs with lots of fish are located from one to eight miles offshore. That means that there is not really any free snorkeling in the Florida Keys.
We break down snorkeling Florida Keys into three main areas:
And here was the big surprise for us snorkeling Florida Keys. While we thought that the best snorkeling would be both in the Key Largo and Key West areas, (mostly because there are the most advertising boat companies in those areas), in fact the best snorkeling is by far and away accessed from the keys between those two.
We go into each area in detail below.
First let's talk about Key West. This is the most popular destination in the keys, and probably where most people attempt to snorkel from. Despite its popularity, the snorkeling in Key West simply does not compare to what you find further up the keys. The reefs are not as healthy and the visibility is not as good. But, if you are going, there are a few decent options.
You can book snorkel boat trips in Key West. They will take you out to a few reefs and keys that are about eight miles offshore. And there are a few beaches you can snorkel.
But the only snorkeling that is accessed from Key West (but is nowhere near it) that we recommend is snorkeling Dry Tortugas National Park (Fort Jefferson).
Now let's jump up north to Key Largo. The snorkeling in Key Largo is a mixed bag. While not as good as in the middle keys areas, there are lots of boat companies and snorkel spots available from Key Largo.
Most of the snorkeling is focused on the areas close to John Pennekamp Coral Reef State Park. Very popular trips leave from within the state park, and many other trips head to the same waters from outside the park. Destinations include the Christ of the Abyss Statue, Dry Rocks, White Banks, Sea Gardens, and Molasses Reef to name a few.
And now, the best for last. By far and away the Middle Keys offer the best snorkeling grounds. From Islamorada you will want to check out Hen & Chickens and Cheeca Rocks patch reefs. Another spot not to miss is Alligator Reef. Then from Marathon the wonderful Coffins Patch, Pillar Patch, and The Stake are well worth snorkeling, and the amazing Sombrero Reef.
Farther south, the beautiful Bahia Honda State Park is a must see (not so much for it's snorkeling, but it's beautiful beaches).
And just south of Big Pine you will kick yourself if you don't take a tour out to Looe Key Reef.

Really the keys are stunning in many ways. Beautiful views, gorgeous waters and interesting Victorian architecture (in Key West).
The area also has it own unique "keasy" style. Most of the keys outside of Key West are very relaxed, and laid back. So don't expect snappy service, and super clean and neat businesses.
Maybe the most fascinating thing of note about the keys is how they are all connected with one long road, with miles and miles of bridges connecting these little flat pieces of land. The history of the building of these bridges is pretty interesting, and you can see in many places the old original bridges right next to the modern new ones.
