In 1981, the U.S. government began a wide-scale project designed to increase the number of habitats available to marine organisms. One of the program's major accomplishments has been the creation of nearby artificial reefs, which have attracted all kinds of tropical plants, fish, and animals. In addition, Biscayne National Park offers a protected marine environment just south of downtown.
Several dive shops around the city offer organized weekend outings, either to the reefs or to one of over a dozen old shipwrecks around Miami's shores. Check "Divers" in the Yellow Pages for rental equipment and for a full list of undersea tour operators.
