Marked by a red nun buoy, Conch Reef Sanctuary Preservation Area (SPA) is a popular dive spot in the Upper Keys. Located five nautical miles south of Tavernier, Conch Reef has one of the best developed reef walls in the Florida Keys.
The SPA itself is rectangular and covers an area less than one square nautical mile to a depth of 45 feet and adjacent to the Conch Reef Research Only Area, which is not accessible to the public except by permit.
Catch and release trolling is permitted in this SPA; however, all other forms of harvesting are prohibited. It has good conch habitat and contains well-developed stands of rare pillar coral.
