Located just a few miles off the coast of Miami Beach, the Neptune Memorial Reef is one of the most fascinating and beautiful snorkeling destinations in South Florida.
Originally designed as an underwater cemetery, this carefully constructed artificial reef has transformed into a vibrant marine habitat, offering snorkelers the rare chance to explore coral formations, schools of tropical fish, and an underwater world unlike any other in Miami.
If you’re looking for a snorkeling experience that combines natural beauty with a touch of history and mystery, snorkeling Neptune Memorial Reef should be at the top of your list.
What is the Neptune Memorial Reef?
The Neptune Memorial Reef is an underwater reef in Miami, designed as a memorial site to honor loved ones and to create a thriving ecosystem for marine life.
Stretching across over 16 acres of ocean floor, Neptune Reef Miami sits approximately 40 feet below the surface, about 3.5 miles east of Key Biscayne.
Built to resemble the lost city of Atlantis, the site features sculpted gates, pathways, columns, and benches — all now covered with corals, sponges, and sea fans that attract a wide variety of tropical fish, crustaceans, and other marine species. Over time, it has grown into one of the most successful artificial reef projects in the world.
Today, the Neptune Memorial Reef is both a peaceful final resting place and a dynamic underwater adventure destination for snorkelers and divers alike.
Why Snorkel the Neptune Memorial Reef?
Snorkeling Neptune Memorial Reef offers a unique combination you won’t find anywhere else:

Unlike natural reefs closer to shore, the structures at the Neptune Reef Miami provide shelter and surfaces for marine species to thrive, creating a colorful and lively underwater scene.
Some highlights you might see while snorkeling the reef include:
- Parrotfish, angelfish, and butterflyfish swimming through coral-encrusted arches
- Spiny lobsters tucked into stonework nooks
- Barracuda cruising slowly through open spaces
- Hawksbill turtles gliding between columns
