Few American road trips feel as cinematic as the Florida Keys, a coral archipelago tethered to the mainland by the fabled Overseas Highway. From Key Largo’s underwater park to Key West’s sunlit porches and literary ghosts, the Keys mix wild nature with salty, storied culture. This 5-day itinerary strings together reefs, beaches, and breezy waterfront meals—the essence of a Florida Keys vacation.

The Keys have long lured adventurers. Indigenous Calusa and Tequesta peoples thrived here first; Spanish explorers mapped the shoals; and 20th-century engineers stitched islands together with bridges. In 1982, Key West cheekily “seceded” as the Conch Republic, a wink to its independent streak that still flavors daily life. Today, protected waters, historic forts, and pastel cottages invite slow travel and early sunsets.

Expect seafood feasts (stone crab in season, hogfish, spiny lobster), Cuban coffee, and turquoise shallows. Pack reef-safe sunscreen, a hat, and water shoes for shell-y sandbars. Hurricane season runs June–November; winter and spring bring balmy days, clear water, and festivals. Fly into Miami or Key West; rent a car to savor the island-to-island flow.

Key Largo

Welcome to the “Diving Capital of the World,” home to John Pennekamp Coral Reef State Park—the first undersea park in the U.S.—and a living museum of coral canyons, sea fans, and the famed Christ of the Abyss statue. Bayside sunsets, mellow marinas, and conch shacks set the tone for your Florida Keys road trip.

• Top sights: John Pennekamp Coral Reef State Park, Florida Keys Wild Bird Rehabilitation Center, Windley Key Fossil Reef Geological State Park, History of Diving Museum (nearby Islamorada).
• Why stay: Easy access to reefs and sandbars, shorter drive from Miami, and classic, toes-in-the-sand dinners.
• Eats and sips: Mrs. Mac’s Kitchen (key lime everything), The Fish House (local catch, famous matecumbe preparation), Sundowners (sunset on Blackwater Sound), Florida Keys Brewing Co. (tropical ales, beer garden in Islamorada), Midway Cafe & Coffee Bar (power breakfasts, house-baked breads).

Where to stay: Browse canal-front homes or bayside condos on VRBO Key Largo or compare resorts and inns on Hotels.com Key Largo. Look near mile markers 100–104 for quick park access and sunset dining.

How to get here: Fly into Miami (MIA) or Fort Lauderdale (FLL) via Trip.com flights or Kiwi.com flights. Pick up a rental car; drive ~1–1.5 hours (45–70 miles) to Key Largo via the Turnpike/US-1. Expect ~$8–15 in tolls from MIA.

Day 1: Arrival and First Sunset in Key Largo

Afternoon: Arrive and check in. Shake off travel at John Pennekamp’s easy-access beaches—Cannon or Far Beach—for a first peek at seagrass beds and pelicans. Stop by the visitor center’s aquariums to preview reef life and plan tomorrow’s snorkel.

Evening: Sunset dinner at Sundowners (wahoo, mahi, and a coconut-crusted snapper with a view). If you prefer local, head to The Fish House for the signature “matecumbe” topping (tomato, onion, capers, herbs) on fresh fillets. Nightcap with a slice of key lime pie next door at Key Largo Chocolates & Ice Cream.

Day 2: Reefs, Islamorada Flavors, and Middle Keys Highlights

Morning: Power up at Midway Cafe & Coffee Bar (house granola, egg scrambles, superb lattes). Snorkel at John Pennekamp Coral Reef State Park—boat tours run to shallow reefs like Grecian Rocks and the Christ of the Abyss. Expect parrotfish, grunts, and waving sea fans. Non-snorkelers can book a glass-bottom boat to spy the reef without getting wet.

Afternoon: Drive 20–30 minutes to Islamorada. Lunch at Lazy Days (oceanfront; bring-your-catch-friendly) or Morada Bay Beach Café (Caribbean-Med plates under palm trees). Then tour the History of Diving Museum—antique helmets, early scuba tech, and tales of sponge divers. Cap with a tasting at Florida Keys Brewing Co., whose guava wheat and hibiscus ales pair with a shady garden.

Evening: Swing 45 minutes to Marathon for golden hour on the Old Seven Mile Bridge walkway and a casual dinner at Sunset Grille & Raw Bar (sushi, grouper tacos, poolside vibes). Return to Key Largo (about 1 hour) or, if you linger in Islamorada, try live music at Lorelei Cabana Bar over the water.

Key West

End-of-the-road Key West is a mosaic of pastel conch houses, cigar-rolling heritage, Cuban coffee counters, and writers’ haunts. Roosters crow, cats reign at Hemingway’s, and every evening the island throws a party for the sun at Mallory Square. Waters here are shallow, clear, and irresistible.

• Top sights: Ernest Hemingway Home & Museum, Fort Zachary Taylor Historic State Park, Southernmost Point, Truman Little White House, Key West Lighthouse, Key West Historic Seaport.
• What’s special: Live-music sunset sails, reef-and-wreck snorkeling, sandbar picnics in the marine sanctuary, and a food scene that swings from Cuban staples to inventive tapas.
• Eats and sips: Blue Heaven (brunch with roosters), El Siboney (Cuban classics), Santiago’s Bodega (tapas), Louie’s Backyard (elegant oceanfront), Garbo’s Grill (Korean BBQ mahi tacos), Cuban Coffee Queen (cortaditos).

Where to stay: For walk-everywhere convenience, choose Old Town near Duval/Mallory on VRBO Key West or compare inns and resorts on Hotels.com Key West. New Town brings quieter stays and better parking.

Getting there from Key Largo: Depart after breakfast for the scenic 100-mile drive (~2–2.5 hours) along the Overseas Highway. Breaks worth taking: Bahia Honda State Park (one of Florida’s best beaches), Big Pine Key’s key deer sightings, and the Seven Mile Bridge viewpoints.

Day 3: Overseas Highway to Key West, Hemingway, and a Live-Music Sunset Sail

Morning: Coffee and breakfast sandwiches at Harriette’s Restaurant (don’t miss the muffins) before the drive. Swim or stroll at Bahia Honda State Park—snorkeling is often calm near the old bridge—and grab a quick lunch in Marathon at Keys Fishery (lobster reuben, fresh hogfish).

Afternoon: Arrive in Key West and check in. Wander Old Town: tour the Ernest Hemingway Home (six-toed cats and tales of the 1930s literati) and climb the Key West Lighthouse for a harbor panorama. Cool off with a frozen key lime pie on a stick at Kermit’s.

Evening: Trade Mallory Square’s crowds for a front-row sunset on a catamaran with open bar and appetizers. Book the Key West Signature Sunset Sail with Live Music, Open Bar & Food for a festive two-hour cruise:

Dinner afterward at Santiago’s Bodega (go for the lamb lollipops and saganaki) or casual Garbo’s Grill (tucked behind The Gardens Hotel, famous for mahi tacos). Nightcap with funk and brass at the Green Parrot Bar.

Day 4: Dolphins, Sandbars, and Fort Zach Beach Time

Morning: Fuel up at Cuban Coffee Queen (cortadito, Cuban toast) and head out on an all-inclusive sandbar-and-dolphin outing in the Florida Keys National Marine Sanctuary. It’s the classic Key West day on the water—snorkeling, clear shallows, and playful bottlenose sightings:

All-Inclusive Sandbar Safari with Dolphin Playground Encounter

Afternoon: Beach time at Fort Zachary Taylor Historic State Park, the island’s prettiest stretch for swimming and snorkeling (bring water shoes). Tour the Civil War-era fort for a dash of history, then grab a gelato at Duetto’s back in town.

Evening: Sunset street theater at Mallory Square (jugglers, cats that jump through hoops, and that pink-sherbet sky). Dinner at Louie’s Backyard (elegant oceanside dining; consider the snapper and a rum cocktail) or homey El Siboney (ropa vieja, black beans, and the island’s comfort-food core). Slip into Smokin’ Tuna Saloon for late-night live music or a drag show at Aqua on Duval.

Day 5: Bikes, History, and Farewell Flavors

Morning: Rent bikes and cruise the waterfront path to the Southernmost Point buoy before crowds. Tour the Truman Little White House to peek at mid-century presidential life in the tropics. Brunch in the garden at Blue Heaven (eggs Benedict, banana bread, and roaming roosters).

Afternoon: Last-minute bites at Eaton Street Seafood Market (crab cake sandwich, lobster roll) and a stroll through the Historic Seaport to watch tarpon roll beneath the docks. Depart from Key West International (EYW) or drive ~3.5–4 hours to MIA/FLL for flights via Trip.com flights or Kiwi.com flights.
