GTA 6 takes place in Leonida, Rockstar's fictional stand-in for Florida, built around the returning city of Vice City (a modern take on Miami) plus a much larger surrounding state of swamps, small towns, and coastline. Rockstar has described it as "the biggest, most immersive evolution of the Grand Theft Auto series yet."
What Rockstar has officially confirmed
Rockstar's own marketing (the trailers and the rockstargames.com/VI site) has named these regions as part of Leonida:
- Vice City — the neon-lit main city, Rockstar's version of Miami, and the heart of the map.
- Leonida Keys — a chain of islands modeled on the Florida Keys.
- Grassrivers — an Everglades-style wetland/swamp region.
- Port Gellhorn — a working-class coastal town.
- Mount Kalaga (National Park) — a forested, rural area in the north of the map.
- Ambrosia — another named area seen in trailer footage, details still thin.
The official story setup: protagonists Jason Duval and Lucia Caminos get caught up in a criminal conspiracy "stretching across the state of Leonida" after an easy score goes wrong, meaning the game is explicitly built to use the whole state, not just Vice City.
Unofficial region breakdown (fan analysis, unconfirmed)
Trailer footage and leaks have led the GTA fan community to map out likely counties within Leonida. This breakdown is fan analysis, not an official Rockstar map — treat names and borders as best guesses until Rockstar publishes an actual map:
| Area | Located | Notes |
|---|---|---|
| Vice-Dale County | Southeast | Contains Vice City proper |
| Leonard County | East | Seen briefly in trailer shots |
| Ambrosia County | Northeast | Rural/small-town feel |
| Kelly County | Northwest | Includes Port Gellhorn |
| Mariana County | Southwest | Includes Grassrivers and the Leonida Keys |
How big is the GTA 6 map?
Rockstar has not published an official size figure for the Leonida map — no square-mile or square-kilometer number has come from Rockstar or Take-Two. Any specific figure you see online (e.g. "125 km²" or "twice the size of GTA V") is a community estimate derived from analyzing trailer footage, flight paths, and draw distances, not a confirmed statistic.
What can be said with more confidence, based on Rockstar's own statements and trailer content:
- The map is built around multiple distinct biomes (dense city, swamp, small coastal towns, rural highway, forest/national park) rather than one city and its outskirts.
- Rockstar has said it wants Leonida to feel like a real, lived-in state, implying more non-urban terrain than GTA V's Los Santos and Blaine County combined.
- Rockstar has also indicated it plans to expand the world after launch, adding new locations over time — so even the day-one map isn't necessarily the map's final size.
Until Rockstar or Take-Two states an exact size or confirms the fan-made county map, treat all "X times bigger than GTA V" claims as unconfirmed speculation.
Vice City itself
Vice City returns as one part of the larger state rather than the entire game world (unlike the original 1986-set Vice City, where the city was effectively the whole map). Trailers have shown a dense, modern downtown with high-rises, a beachfront strip, and surrounding suburbs, consistent with a Miami-inspired metro area rather than a single small download.
Bottom line
Leonida is confirmed to include Vice City, Leonida Keys, Grassrivers, Port Gellhorn, Mount Kalaga, and Ambrosia. No official total map size has been released — anything more specific than that is fan estimation based on trailer analysis, and should be treated as unconfirmed until Rockstar says otherwise.
