Overview
The Florida Keys are an archipelago of roughly 1,700 islands stretching about 120 miles southwest from the southern tip of mainland Florida into the Gulf of Mexico and Atlantic Ocean. Only a fraction of the islands are inhabited; the main ones are connected by the Overseas Highway (US-1), which crosses 42 bridges including the iconic Seven Mile Bridge.
The Keys are divided loosely into the Upper Keys (Key Largo, Islamorada), the Middle Keys (Marathon), and the Lower Keys (Big Pine Key, Summerland Key), culminating in Key West at the southernmost tip. Each area has a distinct character — Key Largo is a hub for diving and snorkeling, Islamorada is known as the "Sport Fishing Capital of the World," Marathon is family-oriented and quieter, and Key West carries a historic, bohemian energy.
The ecosystem here is as significant as the scenery. The Florida Keys National Marine Sanctuary protects a vast swath of coral reef, seagrass, and mangrove habitat. Visitors come for world-class underwater experiences, but the above-water fishing, kayaking, sunset-watching, and open-air dining culture are equally compelling.
Because it is a long, narrow chain of islands with a single main road running its length, planning your itinerary around geography — rather than jumping back and forth — will save significant travel time.
Before You Go
Visas and Entry
The Florida Keys are part of the United States. Entry requirements depend on your nationality and travel history. Check TravelerPulse's Visas section and the official US Customs and Border Protection website (cbp.gov) for current requirements before booking.
When to Go
The dry season runs roughly November through April. This period offers lower humidity, clearer skies, and calmer seas — ideal for diving and fishing. Summer (June–September) brings heat, high humidity, frequent afternoon thunderstorms, and the peak of Atlantic hurricane season (June 1 – November 30). Spring break (March–April) and New Year's Eve in Key West are extremely busy; book accommodation months in advance for those periods.
Health and Insurance
No vaccinations are specifically required for domestic US travel. Mosquitoes and no-see-ums can be a genuine nuisance, particularly after rain and near mangroves — pack insect repellent. Sunburn is a serious risk year-round due to strong tropical sun reflected off water. Comprehensive travel or health insurance is recommended, especially if planning water sports.
What to Pack
- Lightweight, breathable clothing; a light layer for air-conditioned restaurants
- Water shoes or reef-safe sandals
- Reef-safe sunscreen (required in the Florida Keys National Marine Sanctuary)
- Polarized sunglasses
- Dry bag for on-water activities
Getting There
By Air
Key West International Airport (EYW) receives direct flights from several US cities, though the network is limited and fares can be high. Miami International Airport (MIA) and Fort Lauderdale-Hollywood International Airport (FLL) are the most practical entry points for most visitors; both are major hubs with extensive domestic and international connections. From either airport, the Keys are accessible by rental car or shuttle.
By Car
Driving is the most flexible way to arrive and move through the Keys. From Miami, US-1 south takes you onto the Overseas Highway. The drive from Florida City (the last mainland town) to Key West is approximately 106 miles, but plan for at least 2.5–3 hours without stops — traffic through the single-road corridor can be slow, particularly on Friday afternoons and Sunday evenings.
By Bus / Shuttle
The Keys Shuttle and similar shared-ride shuttle services operate between Miami and Fort Lauderdale airports and various Keys destinations. Greyhound and Florida Keys Shuttle connect to Key West. Verify current schedules and pricing directly with operators, as services change.
By Boat
Private and charter boats can access the Keys through the Intracoastal Waterway and the Atlantic. Marina space is limited in peak season; reservations are essential.
Getting Around
Car
A rental car is strongly recommended if you plan to explore beyond a single town. The Overseas Highway (US-1) is the only through-road; mile markers (MM) run from MM 126 near Florida City down to MM 0 in Key West and are used by locals to give directions.
Key West
Key West is compact enough to explore on foot, bicycle, or scooter. Numerous rental shops offer bicycles, mopeds, and electric bikes — a practical and popular way to get around the island. The City of Key West operates a bus system (Key West Transit); verify current routes and fares on the city's official site.
The Florida Keys Overview (Bike / Walking Paths)
The Florida Keys Overseas Heritage Trail is a developing multi-use trail running the length of the Keys; many sections are complete, making cycling between towns feasible in some areas. Verify current completed segments before planning a cycling trip.
Boat
Water taxis and charter boats operate between some islands, particularly in and around Key West. This is an enjoyable alternative for short hops. Confirm current operators and schedules locally.
Where to Stay
Accommodation in the Florida Keys ranges from large resort properties and boutique hotels to independent motels, vacation rental homes, RV parks, and campgrounds. The concentration of options is highest in Key West, Key Largo, Islamorada, and Marathon.
General Guidance by Area
- Key Largo / Islamorada: Good base for diving and fishing; quieter evenings, more nature-oriented.
- Marathon: Family-friendly; mid-point location suits those exploring the full chain.
- Key West: Best for nightlife, dining variety, walkability, and historic atmosphere; also the most expensive and crowded.
Camping
Bahia Honda State Park and other state parks in the Keys offer campground reservations. These spots book up very quickly — reserve as early as the reservation window allows through the Florida State Parks reservation system.
Practical Notes
- Waterfront rooms with dockage cost a premium.
- Many properties have minimum stay requirements during peak season and holidays.
- Prices vary significantly by season; shoulder periods (May–June, October–November) often offer better value.
- Verify current rates and availability directly with properties or through reputable booking platforms.
Things to See & Do
Diving and Snorkeling
The Florida Keys sit alongside the only living coral barrier reef in the continental United States. John Pennekamp Coral Reef State Park in Key Largo is one of the most visited underwater parks in the country and an excellent starting point. Numerous dive operators throughout the Keys offer guided reef dives, night dives, and wreck dives — notably the USNS General Hoyt S. Vandenberg wreck near Key West. Snorkel tours are widely available and accessible to non-divers.
Fishing
Sport fishing is a core part of Keys culture. Islamorada is a particularly well-regarded base for offshore, deep-sea, and backcountry fishing. Tarpon, bonefish, permit, mahi-mahi, and sailfish are among the targeted species. Dozens of licensed charter captains operate throughout the Keys; most provide gear. A Florida fishing license is required for saltwater fishing unless exempt — check Florida Fish and Wildlife Conservation Commission guidelines.
Wildlife and Nature
- Bahia Honda State Park: One of the finest natural beaches in the Keys, with good snorkeling and bird-watching.
- National Key Deer Refuge (Big Pine Key): Home to the endangered Key deer, a miniature subspecies of white-tailed deer.
- Dolphin Research Center (Grassy Key): Educational, nonprofit facility offering interaction programs; verify current availability and booking requirements directly.
- Dry Tortugas National Park: Accessible by ferry or seaplane from Key West, this remote island cluster features Fort Jefferson and exceptional snorkeling. Plan ahead — the ferry sells out.
Key West Landmarks and Culture
- Mallory Square: The famous nightly Sunset Celebration, with street performers gathering crowds before sundown.
- Ernest Hemingway Home and Museum: The writer lived here in the 1930s; the house museum is open to visitors (verify hours and admission fees on-site).
- Duval Street: The main commercial and nightlife corridor.
- Fort Zachary Taylor Historic State Park: A Civil War-era fort with one of Key West's best beaches.
Food & Drink
Local Specialties
The Florida Keys have a distinct culinary identity shaped by Caribbean and Southern influences and exceptional access to fresh seafood. Expect to encounter these on almost every menu:
- Conch fritters and conch chowder: Conch is the symbol of the Keys. Most conch is now imported (wild harvesting is restricted), but it remains a beloved local dish.
- Key lime pie: The official state pie of Florida and a Keys institution. Authentic Key lime pie is pale yellow (not green), made with Key lime juice, sweetened condensed milk, and a graham cracker crust. Many spots sell it frozen on a stick dipped in chocolate.
- Stone crab claws: In season from October through May, stone crabs are a Florida luxury; only the claws are harvested and the crabs are returned to the water.
- Fresh fish sandwiches and tacos: Mahi-mahi (dolphinfish), grouper, and yellowtail snapper are commonly featured.
Dining Culture
The Keys dining scene ranges from open-air waterfront shacks to upscale restaurants. Dress codes are almost universally casual. Many restaurants close early by big-city standards or have seasonal hours; calling ahead is advisable. Key West has the greatest concentration and variety of dining options.
Drinking
Key West has an especially active bar scene centered on Duval Street. The Keys are also home to several rum distilleries and small craft producers — tours may be available; verify locally. Drinking in public outside designated areas is generally not permitted, though Key West has historically had a more permissive culture around outdoor venues.
Practical Information
Money
The Keys operate entirely on US dollars. ATMs are available throughout the islands, though less so on smaller or less-trafficked keys. Credit cards are widely accepted. Tipping is customary: 18–20% at restaurants, and standard gratuities for fishing charters and dive guides.
Connectivity
Mobile coverage exists along the Overseas Highway and in towns, though it can be patchy in more remote areas and on the water. Most hotels and many restaurants offer Wi-Fi.
Environmental Rules
- Reef-safe sunscreen: Only sunscreens free of oxybenzone and octinoxate are permitted within the Florida Keys National Marine Sanctuary. This is enforced.
- No anchoring on reef: Boaters must use designated moorings over reef areas.
- Wildlife interaction: Feeding or harassing marine wildlife, including manatees, is a federal offense.
- Do not remove coral, shells with living animals, or any protected species from the water.
Utilities and Services
Fresh water is piped from the mainland; the Keys are not water-abundant. Some drought restrictions may apply during dry conditions. Grocery and supply options are reasonable in larger towns (Key West, Marathon, Islamorada) but more limited and expensive in smaller communities.
Safety
General Safety
The Florida Keys are a popular, well-touristed destination with generally low serious crime rates. Key West's Duval Street area can attract petty theft and pickpocketing, particularly during high-traffic events. Exercise standard urban awareness.
Weather and Natural Hazards
- Hurricanes: The Keys are in a high-risk hurricane corridor. If a storm threatens, heed all evacuation orders promptly — the single-road corridor means evacuation must begin early. Monitor the National Hurricane Center (nhc.noaa.gov) during the June–November season.
- Rip currents: Present at ocean-facing beaches. Learn to identify and escape rip currents; swim at supervised beaches where available.
- Marine hazards: Jellyfish, sea urchins, fire coral, and stingrays are present. Shuffle feet in shallow sand, wear water shoes where appropriate, and do not touch marine life.
- Heat: Heat exhaustion is a real risk in summer months. Stay hydrated, limit midday sun exposure, and be aware of symptoms.
Emergency Numbers
In the United States, dial 911 for police, fire, and medical emergencies. Coast Guard emergency on VHF radio Channel 16.
Local Culture & Etiquette
The Florida Keys have a culture notably distinct from mainland Florida. Locals sometimes call themselves "Conches" (pronounced "conks") — a term historically reserved for those born in Key West — and there is a genuine pride in the laid-back, independent character of island life. The semi-serious "Conch Republic" secession declaration of 1982 (a protest against a US Border Patrol checkpoint) is still celebrated annually and reflects the local sense of humor and self-reliance.
The Keys have historically been a welcoming place for diverse communities, including artists, writers, and a sizable LGBTQ+ community, particularly in Key West. Ernest Hemingway, Tennessee Williams, and Jimmy Buffett are among the writers and musicians associated with the islands.
Fishing culture is deeply embedded — the balance between sport fishing tradition and marine conservation is an ongoing and sometimes contentious local conversation. Visitors should be aware of regulations and respectful of both the fishing community and conservation efforts.
Pace is genuinely slower here. The local concept of "Keys disease" — the tendency to let deadlines slip and plans loosen — is both a stereotype and a real cultural marker. Factor flexibility into your schedule.
