Come along as we explore nine of the best places for snorkeling in Marathon Florida.
The Sunshine State is one of the top beach vacation destinations in the continental United States and a good reason to visit. But a real beach area getaway is about more than just the sun and the sand.
Epic snorkeling locations only a short boat trip away can turn a fun getaway for the entire family into a vacation you’ll never forget. I just did a road trip down the Florida Keys from Miami this summer to investigate!
Marathon, Florida, is one of the best Florida vacation destinations for families, couples, and solo travelers interested in snorkeling and other activities like kayaking and even jet skiing!
You also find paddle boards, boat tours, or a dive trip (there are great dive sites around the Florida Keys) are some of the favorite things to do here down south.
Where Is Marathon Florida
It is popular for all sorts of boating, snorkel tours, and sunset cruises to have a great time. It is also renowned for fishing, including deep-sea and reef fishing.
Best of all, the water surrounding Marathon is clear and features the third-largest living coral barrier reef system close to the Caribbean Sea, making for some of the best snorkel locations in the world!
Best Snorkeling In Marathon Florida
1. Sombrero Reef
Marathon is considered part of the Middle Keys in the Florida Keys, and Sombrero Reef is the largest reef in this portion of the Florida Keys Reef Tract.
Sombrero Reef is roughly 4 miles out from the coast of Marathon. Visitors can travel there by personal boat or on organized or private snorkeling trips.
Sombrero Reef is one of the more relatively shallow reefs in the Marathon area, surrounded by sandy areas and crystal-clear waters. Some of the natural beauty of the reef is often visible during low tide, submerged only under a few feet of water.
Depths here range from 2 feet to 30 feet deep, offering snorkeling enthusiasts a great opportunity to explore the reef and its sealife inhabitants up close.
Given the range of depth, Sombrero Reef is a wonderful place to explore for snorkeling in Marathon, Florida, for snorkelers and divers of all ages and experience levels.
From vibrant and colorful fish to sting rays, sea turtles, and so much more, you never know exactly what you’re going to run into at Sombrero Reef.
The lighthouse is another fun spot to visit while snorkeling in this area. Completed in 1858, It isn’t open for tours at this time, but visitors can admire it from the water.
Coffins Patch is another top-notch destination for snorkeling in Marathon Florida. It features six different reefs, each showcasing a different coral.
This is highly uncommon and makes for a unique experience, definitely qualifying Coffins Patch as a premier place to snorkel.
Some of the coral you can expect to find on a visit to Coffins Patch include fairy tail pillar coral, star coral, fire coral, and a few others. You’ll also be lucky to spot the likes of butterfly fish, blue tangs, angelfish, and so much more.
Given the coral and sea life diversity, this is a wonderful place to bring an underwater camera and capture life under the sea!
If you’re traveling with newbie snorkelers and prefer a more shallow portion of the reef to explore, head out to The Stake area. It’s easily identified by the steel pole, visible from the surface. This stretch of reef ranges from 10-15 feet deep.
The Elbow and Sand Circle reefs here also have relatively shallow water at approximately 15 feet. These are amazing spots to enjoy the glorious coral reef and take in countless schools of fish and even lobsters!
On the flip side, the Outer Edge is the preferred portion of Coffins Patch for those looking to scuba dive.
The reef is about 40 feet deep through this stretch. Other highlights at Coffins Patch include the Three Bag Reef Wreck, which features the remains of a shipwreck that occurred in the mid-1800s.
3. Looe Key Reef
Looe Key Reef is commonly considered the very best place for snorkeling in Marathon Florida. The depth here spans 7-30 feet, making it another great snorkel trip spot for snorkelers of all ages and skill levels.
The clarity at Looe Key Reef varies depending on which part of it you are snorkeling through.
The shallower depths often offer amazingly clear waters, allowing snorkelers to explore the reef and catch sight of nearly 150 different species of fish, including yellowtail, parrotfish, moray eel, and barracuda!
Sharks of different varieties are often spotted at Looe Key Reef as well. It’s a great place to visit for snorkelers interested in seeing larger aquatic life. But for those that might be unexpecting, be prepared to see bigger marine life at this reef.
4. Delta Shoal
Delta Shoal is a great place to visit for visitors interested in exploring shipwrecks.
Though the wreckage would be more easily explored by scuba diving, you can still get some interesting views while snorkeling.
The depth here ranges from 6 – 25 feet and features some of the most unique coral structures you’ll come across in the Florida Keys.
Several long, finger-like coral forms can be explored here, as well as numerous coral canyons, where snorkelers will likely find droves of fish hiding away.
Look out for grunts, spiny lobsters, and angelfish, as well as an array of interesting sponges.
Even though it’s a great snorkeling spot, Delta Shoal isn’t super popular. Given that it’s relatively close to the busy Sombrero Reef, it’s a great place to come to escape the crowds.
5. Ivory Shipwreck
The Ivory Shipwreck is not only a fascinating location for exploring and snorkeling in Marathon, Florida, but also a testament to history.
This slave ship sank in 1853 and rests at a depth of about 15 feet.
It’s a really interesting spot to visit and check out, but it is more readily enjoyed as a scuba dive rather than a snorkel session.
Lots of marine life can be spotted here, including bluehead, surgeonfish, and blue tang.

6. Bahia Honda State Park
Bahia Honda State Park is a must-visit spot when spending time in Marathon. It’s a gorgeous park above and below the surface.
There are a number of beaches to visit at this park, but Calusa Beach and Sand Spur Beach are the preferred locations for snorkeling.
Keep in mind that snorkeling from the shore is very different from snorkeling in a reef environment.
The shore at Bahia Honda State Park would be a great first stop for those new to snorkeling when snorkeling in Marathon Florida.
The water clarity is generally pretty good here, and snorkelers can easily spot colorful fish through the seagrass near the rock jetty at Calusa Beach.
7. Sombrero Beach
Sombrero Beach is a great place for visitors who aren’t quite ready for a journey out to Sombrero Reef.
The shore snorkeling here won’t offer the same experience that the reef does, as the sea life in the shore areas is much less plentiful.
It is one of the best clear-water beaches in Florida, and the beautiful white sand makes for the perfect spot to spend a beach day.
Beginner snorkelers will be able to see some coral and small fish just off the shore. The rock shelf is an excellent spot to explore, as some marine life lingers there.
8. Horseshoe Beach
Horseshoe Beach is a lagoon encircled by a rock jetty in the form of a horseshoe, hence the name of the beach.
This isn’t your typical Florida beach, as this small area is fairly rocky and often muddy.
This beach is typically pretty quiet, so it’s a good place for snorkeling in Marathon Florida if you want to avoid the crowds.
Snorkelers can typically spot some small fish species, including tropical fish and jellyfish, as well as some corals. As for bigger sea life, you might spot manatees, rays, and barracuda.
9. Cannon Beach in Pennekamp State Park
Cannon Beach in Pennekamp State Park is another great place to snorkel off the shore for families or those who are just learning to snorkel.
This spot is great because it’s relatively shallow near the shore and still offers glimpses of some beautiful, colorful fish.
For those comfortable with swimming away from the shore a bit, there’s a shipwreck to explore just off this beach as well.
