The John Pennekamp Coral Reef State Park in Key Largo is unique and provides a breathtaking view of the underwater world. Let’s see what more it has to offer!
The History of John Pennekamp Coral Reef State Park
The Florida Keys, which consist of more than 200 distinct islands and islets, are home to the only live coral reef formations in the mainland United States. While researching marine species in the Keys, Dr. Gilbert Voss of the University of Miami’s Marine Institute first became aware of the magnitude of damage to the reef structure.
A biology symposium on safeguarding South Florida’s natural resources was held in Everglades National Park in 1957. In this discussion, Dr. Voss outlined the level of damage occurring to the reef structure he had seen throughout his study.
As tourists collected souvenirs, the coral formations suffered the effects of the tourist industry. Seashells, coral, sponges, sea horses, and other marine life were being pounded, chipped, and dynamited to create tourist trinkets. Vendors swiftly destroyed the coral reefs, which took thousands of years to build. Afterward, Dr. Voss advised that an independent scientific study be launched to safeguard the region.
Commercial interests might easily lead to the extinction of North America’s unique hard coral reef formation if there were no constraints on using the reefs. Dr. Voss was able to enlist conservationists to back up his claims that the reef should be conserved, but his most influential ally later joined the Miami Herald as an assistant editor, John D. Pennekamp.
Pennekamp was instrumental in creating Everglades National Park as the legislative head of a state panel. In 1954, he participated in a civilian team of consultants that assessed the US Fish and Wildlife Service for the Department of the Interior. He served as the inaugural chairman of the Florida Board of Parks and Historic Memorials. Also, he won numerous national, regional, and local conservation prizes.
When the two men came together, they were able to assemble a coalition of environmentalists that would take on the challenge of safeguarding priceless marine resources by using the science of Dr. Voss and the journalistic effort of John Pennekamp.
President Dwight D. Eisenhower designated the region as the Key Largo Coral Reef Preserve in the spring of 1960. The United States’ first underwater park was named John Pennekamp Coral Reef State Park by Florida Governor Leroy Collins during the dedication ceremony on December 10, 1960. In recognition of Pennekamp’s ongoing editorial support of the Miami Herald, Governor Collins named the park Pennekamp Park.
Today, the park is home to shorebirds, marine life, and various tropical plants. During their stay, tourists can see vast living coral formations, marine life, tropical hammocks, and mangrove swamps. Guests can explore the underwater park through glass-bottom boat tours, scuba diving, and snorkeling excursions led by park guides.
In addition, visitors can swim, hike the trails, canoe, and kayak on the property. Together with the protected sea area, the location also has a theater, visitor center, campground, store, and aquarium.

Cannon Beach
The park’s main snorkeling site, Cannon Beach, is where tourists may see the remains of an old Spanish shipwreck about 100 feet offshore. Kayaking, glass-bottom boating, and shore snorkeling are popular at Cannon Beach in Key Largo. It is well-known for an old Spanish shipwreck with genuine cannons from the 17th century positioned along Cannon Beach’s sandy dunes, giving a glimpse into Florida’s past.
The calm, warm water at Cannon Beach, a portion of John Pennekamp Coral Reef State Park, is ideal for both swimmers and non-swimmers. Admire marine life like tropical fish as you stroll along the modest shoreline. If deep diving is your thing, venture further into the center of the beach and feast your eyes on a historic Spanish shipwreck that will enthrall you when you get to the ocean below.
Far Beach
Far Beach, which is a little beach, is the other popular beach in John Pennekamp Coral Reef State Park. Next to it, there is a different parking lot and a few picnic sites.
Far Beach has a smaller parking lot and fewer visitors. You should visit this location if you want to take some beautiful images of John Pennekamp Coral Reef State Park without using a boat. This beach is ideal for swimming, sitting, and enjoying the sun under palm trees.
Popular Activities at John Pennekamp Coral Reef State Park
Many people like seeing the reef from a glass-bottom boat tour, but scuba divers and snorkelers may get a closer look.
Popular activities in the park’s waters include canoeing and kayaking, and there are places where you may fish. Short trails are available for strolling, picnics, and swimming at the beach.
A 30,000-gallon saltwater aquarium and ecological documentaries are shown at the visitor center. There are full-service and youth/group campsites available. Wheelchairs for the beach are free to use.
Glass Bottom Boat Tours
The option of taking a glass-bottom boat tour is available to visitors. After stopping at Molasses Reef, the boat travels six miles offshore into the open sea. Looking through the bottom of the boat at the aquatic life in the reef, guests can see colorful fish, stingrays, turtles, sharks, and the coral reef itself.
Many people like seeing the reef from a glass-bottom boat cruise, but scuba divers and snorkelers may get a closer look. Snorkeling and scuba diving tours allow water sports enthusiasts to view the vibrant coral reef and the well-known Christ of the Deep undersea statue, while glass-bottom boat cruises are available for those who want to stay dry.
Snorkeling
At the park, the snorkeling tours are a well-liked activity. If an individual still needs to get their own snorkeling gear, they can rent it, or they are provided one depending on the snorkeling tour package they booked.
Depending on the trip you bought and the length of the trip, the teacher may opt to visit one to three different locations throughout the tour. A snorkel boat often departs three times every day, however, this depends on the weather. The groups may view jellyfish, lobsters, spotfin butterflyfish, barracudas, and other marine life while snorkeling. If you want an intimate experience with family and friends, private snorkeling tours are also offered.
A crucial component of the Florida Keys ecology, mangrove and seagrass habitats can be found in John Pennekamp Coral Reef State Park. Several species depend on them as habitats; they remove extra nutrients from the water and stabilize the sediments that keep creeks and shorelines together during storms. On windy days or for novice snorkelers, seagrass, and mangrove areas are excellent snorkeling locations because they are frequently shallow and protected.

Boat tours to the reef are advised to take advantage of the park’s diving opportunities properly. The waters off Cannon Beach are a fantastic site for a diver just starting or wanting a refresher.
A PADI Five-Star Gold Palm dive shop with a comprehensive list of scuba training, from open water to instructor, is located within the park. In one day, the Resort Course introduces the beginning diver to both diving and the coral reef.
Divers can participate in two-location, two-tank dives on the four-hour scuba diving tours. There are options for air fills and equipment rentals.
Canoeing & Kayaking
The park features 2 ½ miles of designated mangrove wilderness trails. Various birds and marine creatures can find a home in the mangroves and the pristine waterways surrounding them.
The park concession offers canoe and single- or double-person kayak rentals at the ticket booth. There is a launch for privately owned kayaks and canoes on the main road over the bridge.
The launch is situated next to the classroom for instruction over the bridge. Vehicles can be left in the lot across the street for the day and dropped off in the driveway. Rentals are launched directly behind the concession’s wheelchair-accessible Snorkel Shed.
Hiking
Many people also visit John Pennekamp Coral Reef State Park for its parking trails. The park maintains three nature paths in two different habitats.
Visitors can leisurely observe mangroves and the estuaries that thrive on the Mangrove Trail, a circular boardwalk trail. A greater view of this crucial environment can also be obtained from an observation tower.
Visitors can witness many local hardwood species on the Wild Tamarind Trail, another circle walk that winds through the park’s stunning tropical hardwood hammock. Although it, too, traverses the hardwood hammock, the Grove Trail comes to an end there. Tropical fruit trees have been transplanted into this cultural treasure, much like in Key Largo’s early settlements.
At the Visitor Center parking lot, one must return to where they first started. Hikers can book nature walks led by rangers in advance.
