Why Visit the Florida Keys?

Stretching 120 miles from Key Largo to Key West, the Florida Keys form the only living coral reef in the continental U.S., part of the expansive Florida Keys National Marine Sanctuary. This unique ecosystem supports diverse wildlife, from colorful fish to majestic sea turtles, making it a top destination for eco-tourism. The region’s subtropical climate ensures warm temperatures year-round, with water sports thriving from November to April during the dry season. Beyond nature, the Keys blend Caribbean flair with American accessibility, featuring fresh seafood cuisine, historic sites, and artistic communities. Driving the Overseas Highway itself is an adventure, with bridges offering panoramic ocean views at every turn.

Key Largo: The Diving Capital

Often called the ‘Dive Capital of the World,’ this island is home to John Pennekamp Coral Reef State Park, where you can snorkel or dive amid vibrant corals and the famous Christ of the Abyss statue, a 25-foot bronze sculpture submerged 25 feet underwater. The park spans 70 nautical square miles, protecting diverse marine habitats teeming with tropical fish, rays, and occasionally sharks.

Beyond diving, Key Largo offers golf courses, dolphin encounters at Dolphin Cove, and eco-tours through mangrove tunnels. For relaxation, Robbie’s Marina lets you feed tarpon—massive fish leaping for mullet snacks tossed from the dock. Accommodations range from budget motels to resorts like Baker’s Cay Resort, featuring tropical pools and waterfront dining.
