Rock Key Sanctuary Preservation Area
Rock Key Sanctuary Preservation Area (SPA) contains a concentration of important bank reef habitats within a small area and ranges in depth from 5 to 35 feet, located 1 mile east of Sand Key Light. Rock Key SPA is typical of most reef formations in the area, with a rubble zone and long fingers of coral with sand and coral-filled canyons.
Very high water temperatures in the summer of 2023 have caused widespread coral bleaching and mortality in the Florida Keys. Descriptions of coral cover or coral health on this page may not be accurate based on current conditions.
Special regulations apply here. Learn more about what activities are allowed in this type of zone.
