Key Largo Overview

Key Largo — Northernmost of the Florida Keys (Mile Markers 108 to 90)

Driving from mainland Florida, visitors to the Florida Keys enter the 125-mile-long subtropical island chain at Key Largo, the longest and northernmost island in the Keys.
Key Largo is bordered on the west by Florida Bay and the Everglades National Park backcountry, and to the east by the Atlantic Ocean, home to the clear waters of the Gulf Stream. Visitors can enjoy Key Largo's ties to the sea with attractions including scuba diving, snorkeling, an underwater hotel, sport fishing, eco-tours, beaches and dolphin encounter programs.
The island also offers a variety of onshore attractions including two state parks, nonprofit organizations dedicated to restoring coral reefs, shaded nature trails and a rehabilitation center for wild birds.
Key Largo is best known for John Pennekamp Coral Reef State Park, the first underwater preserve in the United States. In shallow waters adjacent to the park at a site called Key Largo Dry Rocks rests the 9-foot-tall bronze “Christ of the Deep” statue, an iconic landmark for divers and snorkelers. Today the park welcomes more than 650,000 visitors annually who come to explore its nature trails and beaches and observe its abundant underwater wildlife.
Pennekamp is part of the Florida Keys National Marine Sanctuary. The sanctuary covers about 3,800 square miles of coral reefs, seagrass beds and mangrove swamp on both sides of the Keys island chain and throughout the surrounding waters of Florida Bay, the Gulf of Mexico and the Atlantic Ocean.
The sanctuary’s indigenous population comprises more than 6,000 species of marine life and plants. The living reefs off Key Largo are acclaimed as some of the most fascinating scuba diving sites in the world.
Key Largo, often called the Dive Capital of the World, is a prime shallow-reef destination for children and adults who want to try diving for the first time or earn their dive certification. Its leading sites for experienced divers include the Spiegel Grove, one of the largest vessels ever intentionally sunk to become an artificial reef.
The island also is known around the globe for its dolphin interaction attractions and therapy programs.
Key Largo gained movie fame when the 1947 classic “Key Largo,” featuring Humphrey Bogart and Lauren Bacall, hit the silver screen. A local bar, the Caribbean Club, provided a backdrop for some of the movie's scenes.
Bogie's presence is apparent even today in Key Largo. Visitors can cruise aboard the restored 1912 steam-powered vessel from one of his other epic films, “The African Queen.”
Key Largo is about a 60-minute drive from Miami International Airport and a world away from South Florida’s mainland.


Spiegel The 510-foot-long, 84-foot-high retired U.S. Navy landing ship dock is one of the largest ships ever intentionally sunk to create an artificial reef. The sunken vessel attracts legions of fish and other Keys marine life that can be viewed by scuba divers with advanced diving experience. It is positioned about 6 miles off Key Largo and lies 130 feet deep; its minimum depth is about 45 feet. Several mooring buoys provide tie-off points for boats.
