The Florida Keys are a stunning coral cay archipelago that stretches off the southern coast of Florida. This group of islands extends 90 miles (150 km) from Miami to Key West, nestled between the Atlantic Ocean and the Gulf of Mexico. Key West is the southernmost point of the continental U.S., located only 93 miles (150 km) from Cuba. The Florida Keys are home to the largest living coral barrier reef in the United States and the fifth largest in the world, which makes it a popular destination for diving and snorkelling enthusiasts.
Among the keys, Key Largo is the northernmost and most significant island, stretching 33 miles (53 km). The archipelago follows an arc, extending from the Florida peninsula, moving south-southwest and westward to Key West, the westernmost inhabited island. While Key West and other islands are inhabited, there are also uninhabited islands like the Dry Tortugas, which are rich in history and natural beauty.
The total land area of the Florida Keys is about 137.3 square miles (356 km²), and most of this lies within Monroe County. According to the 2010 census, the population was 73,090, with an average density of about 532.34 per square mile. By 2020, the population had grown to 82,874, with 32% concentrated in Key West.

How Many Keys Are In The Florida Keys?
If you’ve ever wondered about the Florida Keys, the answer is that there are about 25 primary keys in the area, each with its own story and history. To truly define what a key is, consider it a small island, and the name Florida Keys comes from a long history in Florida. Taking a little trip through this history reveals the meaning behind the name and how the number of keys came to be known over time. The Florida Keys are unique in that they aren’t just islands but also pieces of Florida’s culture and geography, making it a special place to explore.
The Story Behind the Florida Keys
The Florida Keys have a fascinating history that dates back centuries. The first to inhabit these islands were the Native American tribes, the Calusa and Tequesta. In the 16th century, Ponce de Leon, while searching for the Fountain of Youth, arrived in Florida and began exploring the islands. The Spaniards soon charted the area and referred to the islands as “los cayos,” which translates to little island in Spanish. This began the Florida Keys’ connection to the Spanish language and culture.
Over time, Key West became a central point in the area. Initially known as Cayo Huesso, or Bone Island, due to the large amount of bones found by the Spaniards, the name later evolved. English sailors found the name difficult to pronounce, so it became Kay Way-so, which eventually transformed into the familiar name of Key West. The island grew into the largest town in Florida, thanks to its prosperous economy, which was mainly driven by wrecking revenues from ships passing through the area.
The Florida Keys were an essential location for trade, especially with Cuba and the Bahamas, and were situated on the main trade route connecting New Orleans. However, as navigation improved and fewer shipwrecks occurred, Key West began to decline in the late nineteenth century. Despite this, the Florida Keys remain a key part of Florida’s history, culture, and geography, each key holding a unique place in the story of the region.
Total Number of Keys in the Florida Keys
The Florida Keys are home to over 800 keys spread across an expansive archipelago, stretching 120 miles from Key Largo to Key West. What’s cool is that each of these islands has a name, making the Florida Keys even more unique. From the bustling Key West to the more tranquil Key Largo, the islands are all part of this stunning stretch, making it a must-see for anyone visiting the area.

The rest of the Keys are much less populated, giving them a more relaxed, local vibe that makes them feel different from the busy atmosphere of Key West.
Number of Bridges in the Florida Keys
The Florida Keys are connected by 42 bridges that link the islands together. One of the most famous is the Seven Mile Bridge, which connects Knight’s Key to Little Duck in the Middle Keys. This bridge is part of the route that leads from Marathon to Key West. You’ll cross two bridges when driving, as the modern bridge is next to the old one, which has a fascinating history. In the early 1900s, Henry Flagler sought to extend his Florida East Coast Railway to Key West. Unfortunately, the original bridge was destroyed in 1935 by the strongest hurricane in the United States. The railway was then converted into a roadway, and in 1982, a new bridge was built, replacing the old one. Today, the Old Seven Mile Bridge is a popular spot to bike, walk, and fish in the Middle Keys, or you can take a tram ride on the Pidgeon Key Express to visit the historic Pidgeon Key.
