Overview
Big Coppitt Key is a small, largely residential island situated along the Overseas Highway (US-1) in Monroe County, Florida, roughly 8 miles northeast of Key West. With a population of around 2,400 people, it sits firmly outside the tourist circuit and offers a glimpse of everyday life in the Lower Florida Keys rather than a curated visitor experience.
The island is part of the chain of islands collectively called the Florida Keys, strung together by the Overseas Highway — one of the most scenic drives in the United States. Big Coppitt Key itself is flat, low-lying, and fringed by mangroves and shallow tidal flats, typical of the Lower Keys landscape. The surrounding waters are part of the Florida Keys National Marine Sanctuary.
For travelers, Big Coppitt Key functions primarily as a convenient and generally quieter base for reaching Key West to the southwest and the less-visited Lower Keys communities — Stock Island, Cudjoe Key, Sugarloaf Key — to the northeast. Accommodation options are limited compared to Key West, and dining choices are few, so visitors should plan accordingly.
Before You Go
Big Coppitt Key is reached via US-1, and virtually all visitors arrive by car. There are no major visitor centers or tourist infrastructure on the island itself, so it is worth downloading offline maps and planning fuel and grocery stops in advance — Key West to the southwest and larger commercial areas on nearby Stock Island are your best bets for stocking up.
Visas
Big Coppitt Key is a domestic US destination. International travelers should check the TravelerPulse Visas section and the official US Citizenship and Immigration Services (USCIS) website for current entry requirements applicable to their nationality.
Health and practical notes
- Sun and heat: The subtropical climate means intense sun year-round. High-SPF reef-safe sunscreen, a hat, and plenty of water are essential.
- Insects: Mosquitoes and no-see-ums (biting midges) can be a serious nuisance, especially in summer and near mangrove areas. Bring insect repellent.
- Hurricane season: June through November is the Atlantic hurricane season. Monitor the National Hurricane Center (nhc.noaa.gov) if traveling during this period and have a plan for evacuating the Keys if a storm threatens, as US-1 is the only road out.
Getting There
By Air
The nearest commercial airport is Key West International Airport (EYW), located approximately 9 miles southwest of Big Coppitt Key. It serves domestic flights from several US cities. Miami International Airport (MIA), roughly 110 miles north, offers far broader flight connections and is a common arrival point for travelers who then drive the Overseas Highway south.
By Car
Driving is the dominant way to reach Big Coppitt Key. From Miami, take Florida's Turnpike south to US-1 (the Overseas Highway) and continue southwest through the Keys. The drive from Miami to Big Coppitt Key typically takes two and a half to three and a half hours depending on traffic — weekend and holiday traffic on US-1 can be significant. Mile Marker (MM) references are used throughout the Keys; Big Coppitt Key sits roughly around MM 10–11.
By Bus
Florida Keys transit options are limited. Verify current schedules and coverage with the Monroe County Transit system or locally before relying on public bus service.
Getting Around
A personal vehicle is effectively essential for getting around Big Coppitt Key and the surrounding area. The island itself is small enough to walk or cycle across, but reaching Key West, nearby nature areas, or services on adjacent keys requires driving along US-1.
Bicycling is a practical option for short distances during cooler months, though the Overseas Highway has narrow shoulders in places and traffic can move quickly. Always use lights and high-visibility gear. Rideshare services such as Uber and Lyft operate in the Key West area, but availability on Big Coppitt Key specifically may be limited — verify locally. Key West, just a short drive away, offers more robust transportation options including trolleys and bike rentals.
Things to See & Do
Big Coppitt Key is not an activities destination in its own right, but its location makes it a practical launching point for several worthwhile experiences in the region.
On and near the water
- Fishing: The flats and nearshore waters around the Lower Keys are renowned among anglers for bonefish, tarpon, and permit. Local fishing guides operate throughout this stretch of the Keys; verify charter availability locally or through Monroe County tourism resources.
- Snorkeling and diving: Looe Key National Marine Sanctuary, part of the Florida Keys reef tract, is accessible from nearby Bahia Honda and Ramrod Key. It is considered one of the finest snorkeling and diving reefs in North America. Book trips through operators on Ramrod Key or in Key West.
- Kayaking and paddleboarding: The shallow backcountry waters and mangrove creeks throughout the Lower Keys offer calm paddling. Rentals and guided eco-tours are available in Key West and at various outfitters on neighboring keys.
Nearby nature
- Bahia Honda State Park (approximately 20 miles northeast) features one of the best natural sand beaches in the Florida Keys, nature trails, and snorkel tours to Looe Key reef.
- National Key Deer Refuge on Big Pine Key protects the miniature Key deer, a subspecies found only in the Lower Keys.
Key West
Key West is under 20 minutes by car and offers historic sites (Hemingway Home, Fort Zachary Taylor Historic State Park), the Duval Street corridor, sunset celebrations at Mallory Square, and a wide range of dining and cultural attractions.
Food & Drink
Dining options directly on Big Coppitt Key are very limited, reflecting its residential character. Travelers staying on the island should plan most meals in Key West or at establishments on neighboring Stock Island, which has developed a modest food and marina scene in recent years.
Key West, a short drive away, offers a wide spectrum of dining — from casual seafood shacks to more refined restaurants. Fresh local seafood, including Florida spiny lobster (in season, typically August through March), stone crab claws (in season October through May), and fresh fish, is a genuine regional highlight. Key lime pie, made with the small, tart Key limes grown in South Florida, is the area's iconic dessert and worth seeking out at a bakery or restaurant that makes it from scratch.
If you are self-catering, stock up on groceries in Key West before arriving on Big Coppitt Key, as large supermarkets are not on the island itself.
Practical Information
Emergency Services
For emergencies in the United States, dial 911. Monroe County Sheriff's Office and Florida Highway Patrol serve the Keys. The nearest hospital with emergency services is Lower Keys Medical Center in Key West — verify its current status and services before travel.
Fuel and Supplies
Gas stations and grocery stores are not abundant in the Lower Keys. Fill your tank and stock supplies when you have the opportunity rather than waiting until you need them. Prices for fuel and goods in the Keys tend to be higher than mainland Florida averages.
Connectivity
Cell coverage is generally available along US-1 but can be spotty in more remote areas of the Keys. Download offline maps before arriving.
Money
Credit and debit cards are widely accepted. ATMs are available in Key West. Carry some cash for smaller vendors, bait shops, or local markets.
Tipping
Standard US tipping norms apply: 18–20% at sit-down restaurants, a few dollars for bar service, and customary gratuities for fishing guides and tour operators.
Safety
Big Coppitt Key is a quiet residential community with no particular safety concerns for visitors beyond those relevant to the Florida Keys generally.
Weather and water: The greatest safety risks are environmental — intense sun, dehydration, and water-related hazards. Always wear a life jacket when boating, be aware of boat traffic in channels, and heed posted water conditions. Do not snorkel or swim alone.
Wildlife: Avoid feeding or approaching wildlife, including the protected Key deer on Big Pine Key. Stingrays rest in shallow sandy flats; shuffle your feet when wading to avoid stepping on one. Leave marine life and coral undisturbed.
Hurricane preparedness: If a hurricane watch or warning is issued for the Keys, take evacuation orders seriously. The Keys are a narrow strip of low-lying land with a single evacuation route (US-1 north), and official evacuation orders should be followed without delay.
