Leonida, the state where GTA VI takes place, is a fictional version of Florida. Rockstar has confirmed its six regions on the game’s official website and, in Game Informer’s September 2026 cover story, finally gave an idea of its size: roughly twice GTA V’s map.
Size: roughly twice GTA V
Rockstar describes Leonida as about twice the size of GTA V’s map and, above all, denser: more buildings with interiors and more things to interact with than in any previous GTA. There is no official figure in square kilometres.
Before that, the community had made its own estimates from the trailers. How they were worked out and how close they came is explained by Return to Vice in the GTA 6 map size.
The six regions of Leonida
| Region | What it is | Real-world inspiration |
|---|---|---|
| Vice City | The big city: beaches, skyscrapers, clubs and neighbourhoods | Miami |
| Leonida Keys | The southern archipelago, linked by bridges over the sea | Florida Keys |
| Grassrivers | Swamps and mangroves, with airboats and alligators | Everglades |
| Port Gellhorn | Industrial port city on the west coast | Florida’s Gulf Coast |
| Ambrosia | Farming and industrial area by the big lake | Lake Okeechobee area |
| Mount Kalaga | Mountain and forest national park in the north | North Florida (with invented relief) |
Vice City
Leonida’s big city and the heart of the game. The trailers have shown its art deco seafront, packed beaches, financial district, marinas and nightlife. It is far bigger than the 2002 Vice City, an island you could cross in a few minutes.
Leonida Keys
A chain of southern islands linked by long viaducts over the sea, with small towns, marinas and waters for diving.
Grassrivers
The swamps, inspired by the Everglades. You get around by airboat, and they are full of wildlife: the alligator is almost Leonida’s symbol.
Port Gellhorn
A poorer, working-class city on the west coast, with docks, industry and roadside motels: a contrast with Vice City’s luxury.
Ambrosia
The inland area by the lake, agricultural and industrial.
Mount Kalaga
The only real high ground on the map: a mountain and forest national park in the north. Real Florida is flat, so Rockstar has taken a liberty here.
Wildlife and weather
Leonida has more than 170 animal species, including over 60 types of birds, and localized, persistent weather with tropical storms and hurricanes: it can rain in one region while it is sunny in another. We summarise it all in what Game Informer revealed about Leonida.
