There are hundreds of Keys in the Florida Keys , but the exact count depends on how you define a “Key.”

  • Many modern travel and education sources say there are around 800 Keys in the Florida Keys region, stretching roughly 120–180 miles from north to south.
  • Broader geographic counts (including every tiny islet and reef island in the surrounding marine sanctuary) say there are over 1,700 islands total , of which about 800 are considered true “Keys” (low-lying coral/limestone islands).
  • Only a few dozen Keys are inhabited (commonly quoted as roughly 30–40), and only about 40 can be reached by car via the Overseas Highway.

So, if you’re looking for a simple, practical answer to “how many keys are in the Florida Keys?” the most widely used figure is:

About 800 Keys in the Florida Keys archipelago, with only a few dozen inhabited and car-accessible.

Quick Scoop: What Counts as a “Key”?

  • A Key is a particular kind of island: low-lying, coral and limestone based, formed over time by reef and sediment buildup.
  • That’s why some sources talk about 1,700+ islands but only ~800 Keys —not every island in the region meets the geological definition of a Key.

Think of it like this: all Keys are islands, but not all islands are Keys.

Little Story-Style Snapshot

Imagine you’re driving south from Miami.
You hit the first bridge and suddenly you’re skimming just above turquoise water.
On maps, it might look like you’re going through just a handful of islands, but behind those names—Key Largo, Islamorada, Marathon, Big Pine, Key West—there are hundreds of smaller Keys , many uninhabited, some only visible as low strips of mangroves and sand.

Most travelers will only ever set foot on a dozen or fewer, but all told, the chain hiding beyond the guardrails runs to roughly 800 distinct Keys.
