Key Largo: John Pennekamp State Park & Coral Reefs

Key Largo is the largest, northernmost, and first island of the Florida Keys chain, spanning Mile Markers 95 to 108 along the Overseas Highway. Crowned as the 'Diving Capital of the World', Key Largo is world-famous as the home of John Pennekamp Coral Reef State Park—the very first undersea park in the United States, established in 1960. Covering 70 nautical square miles of living coral reef, mangrove swamps, and seagrass beds, visitors can snorkel above the 8.5-foot submerged bronze statue Christ of the Abyss, cruise on high-speed glass-bottom catamarans, or ride the historic 1912 steamboat African Queen. The wider island directory and travel planner starts on the Key West City Guide homepage.

Key takeaways

  • Best visited en route: because Key Largo is a 2-hour drive from Key West, it is most conveniently visited on your drive from Miami to Key West or vice versa.
  • Christ of the Abyss: an 8.5-foot bronze statue resting in 25 feet of water at Dry Rocks reef; its outstretched arms reach within 8 to 10 feet of the surface.
  • Glass-bottom boat: the 65-foot catamaran Spirit of Pennekamp offers seated, climate-controlled viewing of living coral reefs for non-snorkelers.
  • Kayaking mangroves: rent single or double kayaks inside the park to paddle 2.5 miles of calm, protected saltwater mangrove trails.

The Christ of the Abyss at Key Largo Dry Rocks

The undisputed icon of John Pennekamp State Park is Christ of the Abyss, an 8.5-foot bronze statue of Jesus Christ with arms raised toward the ocean surface. Cast from a mold by Italian sculptor Guido Galletti, the statue was donated to the Underwater Society of America by industrialist Egidio Cressi in 1961 and lowered into 25 feet of water at Key Largo Dry Rocks in August 1965.

Resting in a natural sand canyon framed by towering brain and fire corals, the statue's fingertips rise to within 8 to 10 feet of the surface. On calm, sunny days with 50+ feet of visibility, snorkelers floating on the surface can clearly see the bronze features, while free-divers can descend down to photograph the monument up close. Yellowtail snapper, blue tangs, and barracuda regularly circle the statue.

Molasses Reef and glass-bottom boat excursions

For visitors who prefer not to snorkel, Pennekamp Park operates the Spirit of Pennekamp, a high-speed 65-foot catamaran equipped with giant panoramic bottom viewing windows. The tour heads out to Molasses Reef, widely considered one of the healthiest and most vibrant barrier reef systems in North America.

Through the crystal-clear glass panels, passengers watch massive spur-and-groove star corals, towering purple sea fans, green moray eels, nurse sharks, and sea turtles glide beneath the hull, while an onboard marine naturalist provides live educational commentary.

Kayaking mangrove trails and Cannon Beach

Inside the park boundaries, Cannon Beach offers a calm swimming cove featuring the submerged remnants of an authentic early 18th-century Spanish shipwreck, with replica cannons placed in shallow water just 100 feet from shore.

The park's marina also rents sit-on-top kayaks and stand-up paddleboards. A marked 2.5-mile water trail winds through dense red mangrove channels where tree crabs scurry across arching prop roots and upside-down jellyfish (Cassiopea) carpet the quiet sandy shallows.
