Southeast of Miami off Key Biscayne, the snorkeling over the Half Moon wreck is known to be excellent. The calm, shallow waters allow a great opportunity to view the wreck of the 1908 Half Moon in 10 feet of water. The hull has soft corals and sea fans which is good habitat for the angelfish, damselfish and other reef fish.
The Half Moon wreck is located about 225 feet to the northwest of red marker #2 coming out of Bear Cut channel. 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, Half Moon Preserve is the 16th most popular snorkel dive spot of all 24 snorkeling dives in Florida Southeast.
