Things To Do In Key Largo
1. John Pennekamp Coral Reef State Park
The John Pennekamp Coral Reef State Park has long been hailed as one of the best things to do in Key Largo.
It was set up in 1963 as a way of protecting the remnants of the country’s last living coral reef, named after John D. Pennekamp, former editor of the Miami newspaper.
His work in the preservation of the area and the development of the Everglades National Park.
The John Pennekamp Coral Reef State Park covers a wide range of different areas, with marine life, tropical vegetation, and many different flora and fauna to enjoy and view.
The beach portion of the state park is all-natural, a formation of coral and rock, packed with birds like warblers, white ibises, catbirds, and egrets.
Along the beach, you’ll be able to participate in a wide range of activities, ranging from snorkeling to kayaking or canoeing and from boat tours to picnics.
In the summer, it’s great to come early to watch the sunrise, too.
Hiking trails are also a fairly popular part of the John Pennekamp Coral Reef State Park.
A boardwalk forms The Mangrove Trail in the swamp area and the Grove Trail and Wild Tamarind Trail bring you on a loop through a hammock of tropical hardwood and other flora, with informational plaques affixed to trees.
Rangers also lead nature walks, which you can book in advance for your Key Largo trip.
The Visitor Center of the John Pennekamp Coral Reef State Park is a large saltwater aquarium that boasts 30,000 gallons.
Invertebrates, corals, and fish are on display with information that identifies them, and there are hour-long nature films about coral showcased in the theater.
The camp also has a campsite that is always open.

2. African Queen Canal Cruise
The African Queen Canal Cruise is a simple cruise that brings you through the Port Largo Canals, to the beginning of the Atlantic Ocean, and finally back to its origin point at Marina Del Mar.
Though a fun experience in itself, it is not the cruise specifically that makes this one of Key Largo’s top 10 ways to spend your time.
That value lies, for the most part, in its history.
The African Queen rose to popularity after gaining fame in a movie of the same name in 1951, which starred Katharine Hepburn and Humphrey Bogart.
The boat had been being used since the 1910s for service in the Belgian Congo, designed with a vertical boiler and riveted steel.
Back then, it was used for the transportation of missionaries, hunting parties, and cargo.
John Hutson, the movie’s director, saw it while hunting and immediately wanted it for his film.
After being immortalized, the African Queen went back to its original purposes, but in the 1960s, it was abandoned.
It wasn’t until 1968 where it was found in Cairo, Egypt, half-sunken and in bad shape.
In 1982, it found a new purpose in Key Largo as a boat for tours and cruises – a purpose it continues to serve today.

3. USS Spiegel Grove Wreck
Looking for diving-related tourist attractions in Key Largo?
The USS Spiegel Grove Wreck is a fantastic choice!
Spanning 500 feet in length, the ship was once used for dock landings between 1955 and 1989 by the US Navy.
In 2002, it sank, and today it still rests beneath the waves of Key Largo, waiting to be explored.
The wreck is huge, offering many opportunities to find hidden corners and secret spots.
Horse-eye jacks, corals, and barracuda are scattered throughout the USS Spiegel Grove Wreck, naturally taking refuge among the bits and pieces of rubble and remnants of the structure.
Minnows and groupers also dart about.
In order to get to the USS Spiegel Grove Wreck, you’ll dive approximately 70 feet into the water below.
Strong currents mean that this can be a dangerous spot for the inexperienced, so only seasoned divers should attempt to make it here without a guide or teacher.
