How to get to the Florida Keys from mainland Florida

From mainland Florida and Miami International Airport you can reach the Florida Keys by driving along the US 1 highway. The highway goes directly from Miami through the Everglades National Park to the most northerly key, Key Largo. If you want to avoid traffic on US 1, you can try the less trafficked FL 997 and Card Sound Rd to FL 905 in Key Largo.

From this point take the Overseas Highway which connects all the keys from the north to Key West at the very south.

From Miami take the US 1 highway down to the Florida Turnpike. Then go south to Exit 4 - Homestead/Key West. This is the Turnpike Extension that will connect you to Route US 1 in Florida City. The US 1 – known as the Overseas Highway takes you all the way to Key West.

The journey from Miami which is the closest city to Key Largo is 24 miles. From Key Largo to Key West it is a further 101 miles making the total journey from Miami to America's most southerly city 125 miles.

If you are coming from out of state then or abroad then the closest airport to the Florida Keys is Miami International Airport. The airport runs regular national and international flights throughout the year. A useful alternative is Fort Lauderdale which is quieter and easier to navigate.

How long does it take to get to the Florida Keys?

The journey from Miami, which is the closest large city to the Florida Keys, takes 1 hour and 10 minutes. From Fort Lauderdale which is slightly further north, it takes 1 hour and 40 minutes and from Tallahassee, which is the capital of Florida state, it takes 8 hours.

Driving the entire length of the Overseas Highway will take 4 hours with the bridges and roads from Key Largo to Key West taking the bulk of that time at 3 hours on the road.

Driving route from Florida to Key West

The Florida Keys consist of 800 keys which run in a south westerly arch from Key Largo. They main keys in this archipelago are Key Largo, Islamorada, Marathon, Big Pine and the Lower Keys, and Key West.

The 125-mile-long chain of islands are connected by 42 bridges which run over the Atlantic Ocean, Florida Bay and the Gulf of Mexico.

The majority of the Overseas Highway is two lane which makes its very prone to traffic, so bear this in mind during peak tourist season and time your travels to the next key accordingly. The highway is also very dark at night so be extra cautious travelling after dusk.

The Florida Keys Overseas Highway is marked at each mile by a green marker in descending in order from mile marker 113 at the Miami-Dade/Monroe County line to marker 0 in Key West. The markers are frequently used to denote points of interest and even mark an address. Keep an eye out for the mile markers as they are the best way to navigate the Florida Keys.

The Keys can be divided into three regions:

  • Upper Keys: Stretching from Key Largo into Islamorada. These are the busiest keys as they are easily reached on a day trip or weekend break from Miami and nearby towns.
  • Middle Keys: The 7-mile bridge denotes the Middle Keys separation from the Upper Keys.

    Marathon is the largest key at 10 miles, and the largest city in the middle keys. These keys are much quieter and less populated that the more northerly keys.

    Other notable keys in the middle are Vaca Key, Fat Deer Key and Grassy Key. The Middle Keys are famed for their fishing heritage and it's a great place to try some local crab and lobster.

    Marathon is famous for the Seven Mile Bridge (actually 6.79 miles long), one of the longest segmental bridges in the world.
  • Lower Keys: the lower keys considerably quieter. A region of small islands is connected from the west end of the Seven Mile Bridge at Sunshine Key.

    Key West is the largest city in the Lower Keys. An area typified by its natural beauty. The lower keys are home to wildlife refuges, a national marine sanctuary and a state park and are one of the best places to dive and snorkel in the States.

    Key West is a 2-by-4-mile island and is home to the southernmost point in the continental United States. It lies only 90 miles north of Cuba.

Things you need to know about driving to the Florida Keys

If you are flying in to Florida state then Miami International Airport is the closest airport to the Florida Keys.

Many people prefer to fly into Fort Lauderdale. It's 30 minutes north of Miami, which adds on half an hour to the drive, but flights are often cheaper, queues are shorter and it's easier to manage than the colossus that is Miami.

The fastest route from Miami is along the US1 which goes from Miami all the way to Key West.

A quieter but less direct route is the FL 997 and Card Sound Rd to FL 905 in Key Largo.

As traffic can be a problem on the highway so can parking be a problem in the cities and towns. Key West parking can be particularly difficult, especially in Old Town. It's often easier to park out of town and catch a ride in.

Gas is the same price as the mainland from Key Largo to Marathon, but it rises by about 60 cents south of Marathon, including Key West. There are loads of gas stations on the keys, you will find one every 30 minutes or so.

The Florida Keys have a subtropical climate with warm temperatures all year round. When it rains it is usually a brief downpour followed by sun.
