Big Pine Key: Adolphus Busch Sr.

Laid-back Big Pine Key is rich in tropical, hardwood hammocks and freshwater wetlands that are home to key deer and gators. The premier must-dive wreck off Big Pine Key is the fully intact, 210-foot Adolphus Busch Sr. This former cargo freighter was originally named the Ocean Alley. It was renamed in 1998 after being intentionally sunk by the beer-owning family, Anheuser-Busch.
