John Pennekamp Coral Reef State Park Guide: Snorkeling, Diving & Camping

John Pennekamp Coral Reef State Park stands as a pioneering destination in Key Largo, Florida, renowned as the nation’s first underwater park. Spanning approximately 70 square nautical miles of ocean, it protects vibrant coral ecosystems and offers diverse activities for visitors of all ages.

Historical Foundations of a Marine Marvel

The park’s creation traces back to dedicated conservation efforts in the mid-20th century. Initially proposed as the Key Largo Coral Reef Preserve, it gained federal recognition in 1960 under President Dwight D. Eisenhower. Florida Governor Leroy Collins renamed it in honor of John D. Pennekamp, a Miami Herald editor who championed marine protection through persistent advocacy.

Designated on the National Register of Historic Places in 1972, the park has drawn over a million visitors annually, cementing its status as Florida’s most visited state park. This legacy underscores its role in preserving the only living coral reefs in the continental United States, alongside the Florida Keys National Marine Sanctuary.

Expansive Landscape: From Uplands to Depths

Stretching 25 miles long and three miles wide along Hawk Channel, the park blends terrestrial and aquatic realms. Upland areas feature tropical hammocks and mangrove swamps, while offshore sections safeguard reefs like Molasses Reef, teeming with marine biodiversity.

• Tropical Hammocks: Dense forests with rare plants like West Indian mahogany and Keys thatch palm.
• Mangrove Swamps: Critical habitats for juvenile fish and birds, accessible via canoe or kayak.
• Coral Reefs: Colorful formations hosting over 600 fish species and various invertebrates.

Over six miles of trails wind through these ecosystems, ideal for hiking or biking amid protected flora.
