Florida Keys Mile Markers Map: Discovering Paradise
Last Updated May 26, 2026
The Florida Keys are a national treasure. The more than 1700 islands that make up these southernmost islands are part of paradise in the United States.
The tropical climate, laid-back vibe and quirky culture make the Keys one of the top destinations in Florida and very high on the bucket list of people around the world.
After 40 years of traveling the Florida Keys, we know finding restaurants, towns and destinations had been problems for first-time visitors for many years. The Florida Keys Mile Markers Map will help first time visitors navigate the islands.
Mile Markers in the Florida Keys
Mile markers (MM) in the Florida Keys were installed in the 1980s as a way to help with navigation along U.S. Highway 1 (Overseas Highway).
These green, rectangular signs run from MM 0 in Key West (at Whitehead and Fleming Street) all the way up to MM 127 in Florida City, just before the mainland.
Before the mile markers, directions were often given using landmarks, which could change over time.
The Florida Department of Transportation (FDOT) implemented the system to make it easier for emergency responders, tourists, and locals to locate addresses along the highway.
Today, businesses and attractions in the Keys still use mile markers as reference points for their locations.

You can see the problem of trying to squeeze in too many mile markers. This is a representation of the most popular towns in the Florida Keys.
Navigating Between the Mile Markers – many times you will see an address such as MM 95.5. That tells you the location is 5/10ths of a mile beyond (west) of mile marker 95.
Most Popular Towns in the Florida Keys and Their Mile Marker
There are hundreds of towns in the Florida Keys. Many are truly small towns and others are entire islands that are named like a town.
The five most popular cities in the Florida Keys are:
- Key Largo
- Islamorada
- Marathon
- Big Pine Key
- Key West
Each of these destinations are popular for different reasons, but all share the common beauty, weather and views of the Atlantic and Gulf. Our Guide to Florida Keys can give you complete details.
