Tropical Paradise Defined: The Guide to the Florida Keys & Key West

Stretching over 120 miles off the southern tip of Florida, the Florida Keys form an archipelago of more than 1,700 islands separating the Atlantic Ocean from the Gulf of Mexico. Connected by the Overseas Highway, this island chain is celebrated for its clear turquoise waters, rich marine ecosystems, and laid-back tropical lifestyle.

Whether taking a road trip down the Overseas Highway, diving into the only living coral barrier reef in the continental United States, or booking a luxury island resort, the Florida Keys deliver an unforgettable coastal escape.

Road Tripping the Overseas Highway

The Overseas Highway (U.S. Route 1) spans 113 miles across 42 bridges—including the famous Seven Mile Bridge near Marathon. Driving this highway connects the major inhabited hubs of the Keys, offering ocean vistas at every turn:

• Key Largo: The northernmost major key, famous for shallow coral reefs, shipwrecks, and undersea parks.
• Islamorada: Known as the “Sportfishing Capital of the World,” ideal for deep-sea fishing charters, quiet beaches, and local art galleries.
• Marathon: A family-friendly hub featuring the Turtle Hospital, Sombrero Beach, and immediate access to the Seven Mile Bridge.
• Big Pine Key & The Lower Keys: Home to the National Key Deer Refuge, secluded nature trails, and protected marine sanctuaries.
• Key West: The island chain’s southernmost city, famous for vibrant nightlife, historic Victorian architecture, Conch culture, and daily sunset celebrations.

Marine Life & World-Class Water Adventures

The Florida Keys shelter the third-largest living coral barrier reef system in the world. Warmed year-round by ocean currents, these sheltered waters serve as a sanctuary for diverse marine life.

Top Snorkeling & Diving Spots

• John Pennekamp Coral Reef State Park (Key Largo): The first undersea park in the United States, offering glass-bottom boat tours, mangrove kayak routes, and the underwater Christ of the Abyss statue.
• Molasses Reef (Key Largo): Celebrated for exceptional water clarity, spur-and-groove coral formations, and dense marine life.
• Looe Key Marine Sanctuary (Lower Keys): A protected U-shaped reef system offering ideal snorkeling conditions with shallow depths and high species diversity.

Marine Life Encounters

While exploring the reefs, snorkelers regularly encounter colorful tropical species such as queen angelfish, stoplight parrotfish, and butterflyfish. The surrounding waters are also home to sea turtles, bottlenose dolphins, West Indian manatees, stingrays, and harmless reef shark species, including nurse sharks, blacktip sharks, and lemon sharks.
