John Pennekamp Coral Reef State Park
America's first undersea park is a vast natural wonder, with stunning coral reefs, exotic marine life, and a submerged bronze statue of Christ to explore. Anyone not wanting to dive or snorkel can glide across the reef in a glass-bottom boat; plus there's canoeing and kayaking; and nature trails through the mangrove swamps.
Plenty of boats head out from Key Largo each day, taking anglers to the reef and beyond in search of mahi-mahi, tuna, sailfish, grouper and marlin. In fact it's said that more saltwater fishing world records are broken in the Florida Keys than anywhere else around the globe. There's also excellent backwater fishing for elusive bonefish, and wreck fishing too.
Swim With Dolphins
For a chance to learn about, swim alongside and interact with dolphins, head to the Dolphins Plus or Dolphin Cove marine education centres. Choose from 'structured' or 'natural' swims and then shake a fin, play chase, hitch a ride or accept a cuddle from these fascinating and lovable aquatic mammals.
Visit the Everglades
Be sure to make a trip to the nearby Everglades National Park during Key Largo holidays - a unique natural wilderness of tropical wetlands with breathtaking scenery and abundant wildlife. Walk the Anhinga Trail to spot alligators, turtles and all manner of exotic bird life, then hook up with a ranger to identify them for you. Finish off your trip by kayaking through the sawgrass.
Ride The African Queen
Humphrey Bogart's association with Key Largo doesn't finish with the film of the same name or the memorabilia on the walls of the Caribbean Club - the river steamer from his classic 1951 movie African Queen is permanently moored here. Channel your inner Humphrey or Katharine Hepburn with a canal or dinner cruise aboard.
