GTA 6 Map and World Guide: Leonida, Vice City and Every Region Explained
Rockstar has confirmed more about Grand Theft Auto VI's world than any past GTA got before launch. Here's everything official about the state of Leonida, Vice City and every named region, biome and system that makes up the map.
Grand Theft Auto VI is taking players somewhere Rockstar has never fully built before: the fictional state of Leonida, a sun-soaked, swamp-and-skyline reimagining of Florida built around a new version of Vice City. With the November 19, 2026 launch getting closer, Rockstar has confirmed more about this map ahead of release than it ever has for a previous Grand Theft Auto — named regions, distinct biomes, and the technology behind the water, weather and wildlife that fill them.
Here is everything Rockstar has officially confirmed so far about Leonida, Vice City and the rest of the map, without the fan speculation and unofficial "leaked map" guesswork that circulates around every GTA release.
1. What Is Leonida? GTA 6's Setting Explained
Leonida is the fictional U.S. state Grand Theft Auto VI takes place in — Rockstar's stand-in for Florida, the same way San Andreas has stood in for California and Nevada since Grand Theft Auto V and San Andreas before it. It's a modern-day setting rather than a period piece, and it follows the structure the series has leaned on for two decades: one dense, iconic city surrounded by rural, coastal and wilderness regions that all look and feel distinct from each other.
The regions Rockstar has confirmed by name so far are Vice City itself, Grassrivers, the Leonida Keys, Port Gellhorn, Ambrosia and Mount Kalaga National Park. Together they give the studio the environmental range it has been building toward since Red Dead Redemption 2 — dense urban sprawl, wetlands, open coastline and forested highlands, all inside a single state.
2. Vice City: The Beating Heart of the Map
Vice City remains the map's centerpiece, built as a fictionalized version of Miami — neon signage, Art Deco beachfront hotels, cruise ship ports and a dense high-rise skyline. Footage Rockstar has released so far shows it as the most detailed urban environment the studio has ever built, with layered street-level detail running from Ocean Drive-style strips to marina districts, stadiums and downtown high-rises.
Vice City is also the setting most directly tied to the series' history. It's where 2002's Grand Theft Auto: Vice City took place, and Rockstar has leaned into that connection deliberately — right down to retro-styled promotional art designed to look like a vintage travel postcard, and a companion soundtrack release built around the setting's music culture.
3. Grassrivers: Leonida's Everglades
South and inland of Vice City's skyline sits Grassrivers, Rockstar's version of the Florida Everglades. It's a wetland biome built around swamps, marshland, slow-moving rivers and cypress forest, dotted with small, isolated communities that feel worlds away from the city. It's a sharp change of pace from anything a GTA map has offered before, and Rockstar's own footage has shown it as one of the most distinct environments in the game — alligators moving through shallow water, narrow backroads, and homes built up on stilts.
4. Leonida Keys: Islands and Open Water
At the southern tip of the state sit the Leonida Keys, a chain of small islands connected by long highway bridges over turquoise water, modeled on the real Florida Keys. Between the Keys and the coastline running past Vice City, open water looks set to play a much bigger role in Grand Theft Auto VI than in any past entry — Rockstar's promotional art repeatedly features speedboats, jet skis and seaplanes alongside the usual cars and motorcycles.
5. Port Gellhorn, Ambrosia and Mount Kalaga National Park
Rockstar has also confirmed three more named areas that round out Leonida. Port Gellhorn is a smaller working port town away from Vice City's glamour, giving the map a blue-collar counterpoint to the beachfront resorts. Ambrosia adds another slice of Leonida's rural communities away from the coast. And Mount Kalaga National Park is the state's highland region — forested terrain with lakes and rivers that gives Leonida a landscape the series hasn't really used since Red Dead Redemption 2's mountain regions, a clear departure from the desert backdrops of San Andreas and Los Santos.
6. How Big Is the GTA 6 Map?
Rockstar hasn't published an official square-mileage figure for Leonida, and treat any specific number you see elsewhere as an estimate rather than a confirmed fact. What's widely reported, based on Rockstar's own marketing materials and coverage around the game's reveals, is that the map is roughly three times the size of Red Dead Redemption 2's playable area — itself the biggest world the studio had built before now. Combined with the number of genuinely distinct biomes packed into one state, Leonida is shaping up to be the largest and most varied setting in Grand Theft Auto history, even without an exact figure attached to it.
7. A Living World: Weather, Water and Wildlife
Grand Theft Auto VI runs on an upgraded version of Rockstar's proprietary RAGE engine, and the studio has built its improvements specifically around Leonida's environments. Water is simulated in real time rather than faked, which matters in a state built around swamps, rivers, beaches and open ocean — reflections, currents and boat wakes are all rendered dynamically rather than as fixed effects. Weather is tied into gameplay as well as visuals: rain, wind and storms are built to affect driving conditions and NPC behavior rather than sit purely in the background.
That same emphasis extends to wildlife. Rockstar's own footage has shown alligators moving through Grassrivers' swamps and animals reacting to the state's changing weather and time of day, reinforcing that Leonida is meant to feel like a lived-in ecosystem rather than a static backdrop for missions.
8. Two Protagonists, One Sprawling State
All of this is the backdrop for Grand Theft Auto VI's story, which follows Jason Duval and Lucia Caminos, a criminal couple whose "easy score gone wrong" pulls them into a conspiracy stretching across Leonida. Lucia is the series' first non-optional female protagonist — she isn't an alternate option, but one half of a story the two characters share throughout. Moving between such different biomes over the course of the game means Jason and Lucia's story is built to take them from Vice City's penthouses and marinas all the way out to Grassrivers' backroads and the Keys' open water.

9. Platforms, Performance and What's Still Unconfirmed
Grand Theft Auto VI is confirmed for PlayStation 5, PS5 Pro and Xbox Series X|S, with no PC release announced as of this writing. Rockstar has also confirmed the game runs at 30 frames per second on consoles at launch, with no performance mode promised yet for either platform, and that the single-player game will not include microtransactions or generative AI content. The game releases November 19, 2026, with digital preloading opening a week earlier on November 12.

10. Watch Rockstar's Extended Look at the World
The clearest look at Leonida so far comes from Rockstar's own "Grand Theft Auto VI: An Extended Look," captured entirely from in-game PS5 footage and released through the studio's official channels. It's the best single source for seeing how Vice City, Grassrivers and the Keys actually look in motion, rather than in still screenshots.
