Things to Do in Key Largo: John Pennekamp, the Wreck Fleet, and the Real African Queen

John Pennekamp Coral Reef State Park: the First Underwater Park in the US

John Pennekamp Coral Reef State Park is widely and consistently described across state-park and news sources as the first underwater park in the United States, established around 1960 and named for John D. Pennekamp, a Miami Herald editor credited with championing reef protection -- an NPR piece titled "Florida's John Pennekamp Underwater Park Turns 50," published in December 2010, corroborates a circa-1960 founding. The park is the anchor of Key Largo's dive and snorkel identity, with glass-bottom boat tours for visitors who want to see the reef without getting in the water, and separate snorkel and dive trips out to the reef tract for those who do.

This page did not independently confirm the exact dedication date within 1960 or the full details of Pennekamp's advocacy role -- treat the circa-1960, first-in-the-nation framing as well-corroborated across multiple independent sources rather than fully verified down to the day. Confirm current hours, admission, and glass-bottom-boat or snorkel/dive trip schedules and pricing directly with the park before planning a visit, since those specifics change without national coverage.

The Christ of the Abyss Statue: a Submerged Landmark Near Molasses Reef

The Christ of the Abyss is a submerged bronze statue in the John Pennekamp/Key Largo area, commonly cited as sitting near Molasses Reef/Key Largo Dry Rocks, and it's widely reported across dive and travel sources as a gift to American divers. It's understood -- though only partially corroborated this research pass -- to be a cast from the same mold as the original Cristo degli Abissi, a well-documented Italian statue placed underwater off San Fruttuoso in the 1950s, per Wikipedia's and Atlas Obscura's dedicated "Christ of the Abyss" entries.

Here's the honest gap: the statue's specific donor (commonly attributed in background sources to Italian dive-equipment manufacturer Egidio Cressi/Cressi-sub), its exact installation year (commonly cited as 1965), and the Underwater Society of America's precise role in placing it could not be confirmed via full-text source this research pass -- none of those specifics are stated here as settled fact. It's a snorkel- and dive-accessible site, not something visible from shore or a boat deck; confirm current trip options and conditions directly with a local dive or snorkel operator before planning a visit.

The Spiegel Grove, USCGC Duane, and USCGC Bibb: the Wreck-Diving Fleet

The Spiegel Grove, a decommissioned Navy vessel, was intentionally sunk off Key Largo in 2002 to create an artificial reef, and multiple independent outlets -- Fox13 Tampa Bay, Fox Weather, NBC News, and Keys Weekly -- covered its 10th and 20th anniversaries; Fox Weather describes it as the world's third-largest intentionally sunk ship. The USCGC Duane and USCGC Bibb are separate, real decommissioned Coast Guard cutters also sunk as artificial reefs and actively dived off Key Largo today, per NOAA's Florida Keys National Marine Sanctuary shipwreck-trail page and multiple current dive-operator sites.

Together the three wrecks are concrete, physical backing for the "Dive Capital of the World" branding -- not just a slogan, but an actual fleet of deliberately sunk ships that divers travel here specifically to see. This page did not independently confirm the Duane's and Bibb's exact sinking dates or any specific size-ranking claims beyond the Spiegel Grove's "third-largest" title -- treat those as real, current dive sites rather than sourced to precise dates here. All three require dive certification and a boat trip out; confirm current trip schedules, depth ratings, and pricing directly with a local dive operator.

The African Queen: the Real 1951 Film Boat, Still Running Tours

The African Queen boat used in the 1951 film of the same name, starring Humphrey Bogart and Katharine Hepburn, is documented across multiple independent sources -- Wikipedia's "African Queen (boat)" entry, NBC News' "African Queen sails again, six decades after appearing in Bogart film," Florida Rambler, and Atlas Obscura -- as a real, historic vessel later brought to the Florida Keys, restored, and based in Key Largo today. A currently active business (africanqueenflkeys.com) offers bookable tours as of this research pass, confirming the boat is still operating, not a static museum piece.

This page did not independently confirm the boat's exact build year (commonly cited in background sources as 1912 in England), its current ownership, or its National Register of Historic Places listing status -- none of those specifics are stated here without further verification. Confirm current tour schedules, routes, and pricing directly with the operator before booking.

Dolphins Plus: a Real, Currently Operating Dolphin-Encounter Attraction

Dolphins Plus, located at 101900 Overseas Highway in Key Largo, is a real, currently operating dolphin-encounter attraction, confirmed via its own active booking site (dolphinsplus.com) and a 2026-dated Yelp listing. This page did not independently confirm the attraction's founding year or its current accreditation status -- dolphin-encounter attractions nationally do face ongoing animal-welfare scrutiny as a category, but no Key Largo-specific controversy was found this research pass, and none is asserted here. Confirm current program options, pricing, and any accreditation questions directly with Dolphins Plus before booking.

Key Largo Chocolates: a Real Small Local Shop, Not a Factory Tour

Key Largo Chocolates is a real, small local chocolatier and ice-cream shop, with a keysnews.com article ("Key Largo Chocolates under new ownership," 2021) and an FIU GrowBiz feature documenting its business history, and current Yelp/Tripadvisor listings (accessed 2026) confirming it's still operating. Worth being precise about: this is a small storefront business, not a large-scale "chocolate factory" tour attraction, and that "factory" framing -- which shows up on some tourism sites -- should be treated with caution.

This page did not independently confirm the shop's founding year. Confirm current hours and offerings directly with Key Largo Chocolates before planning a stop.

The 1948 "Key Largo" Film: Not Actually Filmed on Location Here

Here's a direct correction this research pass found repeated, uncorrected, across multiple current tourism and travel sites: the 1948 Bogart/Bacall film simply titled "Key Largo" was not filmed on location in Key Largo. Per Wikipedia's "Key Largo (film)" entry, it was shot primarily on Warner Bros. soundstages and backlot in Hollywood, California -- not in the Florida Keys. Some exterior, Keys-adjacent stock footage may have been used even though principal photography took place in Hollywood, but the on-location filming claim itself is a myth worth correcting plainly rather than repeating.

Locally, the settlement now known as "Key Largo" was historically called "Rock Harbor," and background knowledge -- not independently confirmed via full-text source this research pass -- holds that the area adopted the "Key Largo" name around 1952 to capitalize on the film's popularity. That rename story is genuinely part of how the town got its name, but the exact year and full circumstances shouldn't be stated as a settled fact here; Keys Weekly's "Keys History: Key Largo Offers Plenty of Stories" (title-confirmed, not fully read this pass) is the fuller local account worth reading directly for that history.
