This group of wood stilt houses once stood like flamingos one mile south of Cape Florida in the Bay's shallow seagrass beds but being exposed to the weather, many of the homes didn't remain standing long. In its heyday in the 1960s there were 27 structures on the flats and they were accessible only by water (which at that time made them appealing for illegal activities.). The remaining Stiltsville houses stand on wood or reinforced concrete pilings. The water depth varies from 1-3 feet at low tide and the houses stand generally 10 feet above the shallow water. In 2003, a an non-profit organization called the Stiltsville Trust was established to preserve the structures and showcase Biscayne National Park's marine resources. Public access is by permit only.
