South of Miami, the snorkeling at Crandon Park offers the opportunity to observe marine life including nurse sharks in shallow water coral reefs. The water varies from 2 to 8 feet deep.
To reach the Crandon Park snorkeling, follow SR 913 onto Key Biscayne. Use the first parking area on the left where there is a fee required to park. Head to the north end of the parking lot near the park building. Follow the trail north to the old reef viewing area which is about 0.75 miles.
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, Crandon Park is the 13th most popular snorkel dive spot of all 24 snorkeling dives in Florida Southeast.
