It is the largest artificial reef ever planned and will eventually spread over 16 acres. The Neptune Reef is a re-creation of the legendary Lost City with structures created cremated remains with in water depths down to 40 feet.
The Neptune Memorial Reef is located 3.25 miles east of Key Biscayne. This is a boat-accessed dive site. To reach the snorkeling in southeast Florida by air, there are several options. The most popular option is to fly into Miami International Airport (MIA), which is served by all major US and international airlines. Also nearby, a potentially lower cost option is to fly into Ft Lauderdale airport (FLL). From either of these airports, you can rent a car to drive to the dive site, but watch out for automated cash-less toll highways along the way.
Overall, Neptune Memorial Reef is the 20th most popular snorkel dive spot of all 24 snorkeling dives in Florida Southeast.
