About this spot
The USNS General Hoyt S. Vandenberg is one of the largest artificial reefs in the United States. This former US Navy transport ship was intentionally sunk off Key West to create habitat for marine life. The wreck sits on the seafloor within Florida Keys National Marine Sanctuary, a protected area that ensures strict management of diving activity and marine conservation. The site draws divers seeking both historical exploration and marine encounters. As an artificial reef, the Vandenberg has become home to fish schools, rays, and other Atlantic species. The wreck structure itself offers navigable sections and open areas for different skill levels. The sanctuary designation means the site is well-monitored and access is regulated to protect both the reef ecosystem and the archaeological value of the vessel. Year-round diving is possible in the Keys, though water conditions vary seasonally. The sanctuary's no-stress coral bleaching status indicates healthy reef conditions at the time of survey. Community divers have documented 12 species observations at the site, and video content from three separate dives provides insight into conditions and marine life encounters. The combination of history, marine life, and protected status makes the Vandenberg a distinctive wreck destination.
