History
In the early to mid-1900s, discussions began to protect the coral reefs near Key Largo. By the 1950s, damage from unregulated collecting and salvage raised alarm. With advocacy from Miami Herald editor John D. Pennekamp—who also helped establish Everglades National Park—the area received increasing protections.
In 1960, President Eisenhower established the Key Largo Coral Reef Preserve. Land was later purchased and donated for a formal park site. Florida Governor Leroy Collins renamed the area John Pennekamp Coral Reef State Park, which officially opened in 1963.
Size and Boundaries
Today the park covers roughly 70 sq. miles, from Ocean Reef Club in the north to Rodriguez Key (MM 96) in the south, extending ~3.5 miles offshore. The park is surrounded by and works in partnership with the Florida Keys National Marine Sanctuary.
