Florida’s Treasure Coast tourism region consists of Indian River, St. Lucie and Martin counties on the Atlantic coast. The main city names many travelers recognize are Vero Beach, Sebastian, Fort Pierce, Port St. Lucie and Stuart.

There is also a broader official planning region. The Treasure Coast Regional Planning Council includes Palm Beach County with those three counties. State which definition you mean instead of assuming every map uses the same boundary. Sources and the map were checked October 3, 2026.

Treasure Coast county map

The map below uses actual county polygons from the U.S. Census Bureau TIGERweb county service. The three tourism-region counties are highlighted. Palm Beach is shown in a different color to explain the Planning Council’s broader region.

This is a regional orientation map. It does not show roads, exact beach entrances or travel times. Choose the individual destination guide and current navigation for a trip.

Why some official maps include Palm Beach

Florida’s Treasure Coast tourism organization explicitly describes a three-county region: Indian River, St. Lucie and Martin. That is the definition this site uses for its core local coverage.

The Treasure Coast Regional Planning Council is a four-county interlocal partnership covering Indian River, St. Lucie, Martin and Palm Beach. Its definition serves regional planning. The two uses explain why a planning document may show a wider area than a visitor’s Treasure Coast guide.

Choose a base by the purpose of the trip

For a broad first pass, use the Treasure Coast cities list to distinguish municipalities from neighborhood and community names. Then choose a smaller area to explore. A county label is too broad to settle the day’s parking, beach access or drive.

Port St. Lucie is useful for a riverfront or park plan; Stuart provides a downtown and riverfront starting point; Vero Beach and Sebastian provide northern regional bases. Those are planning suggestions, not a ranking of the counties. The regional guides hub groups specific guides by the decision you want to make.
