The State of Leonida in GTA 6 is divided into six confirmed major GTA 6 regions: Vice City, the Leonida Keys, Grassrivers, Port Gellhorn, Ambrosia, and Mount Kalaga National Park. While Vice City and the Leonida Keys tend to dominate headlines, three of these regions have received comparatively less attention — Grassrivers, Port Gellhorn, and Ambrosia. Here's a detailed look at what's been confirmed about each, what can be reasonably inferred, and what remains speculation.
The Six Regions at a Glance
Before diving into each region, it helps to place all six in context. GTA 6's map is confirmed to be roughly 2.4–2.7 times the size of GTA 5's, with over 700 enterable interiors spread across the state. The six regions are not equal in size or type — they're designed to provide distinct tonal and gameplay variety:
| Region | Primary Character |
|---|---|
| Vice City | Urban / Coastal Metropolis |
| Leonida Keys | Tropical Island Chain |
| Grassrivers | Wetlands / Rural Interior |
| Port Gellhorn | Industrial / Working Port |
| Ambrosia | TBD (undetailed as of this writing) |
| Mount Kalaga National Park | Wilderness / Trails / Off-Road |
The focus of this article is Grassrivers, Port Gellhorn, and Ambrosia.
Grassrivers: GTA 6's Everglades Analog
Grassrivers is the region that most immediately evokes Florida's Everglades — a vast, slow-moving wetland environment that covers a significant portion of south Florida in real life. The name itself, combining "grass" and "rivers," points directly to the saw-grass prairies and winding waterways that define Everglades terrain.
In GTA terms, Grassrivers is likely the game's primary rural and swamp environment. This would make it:
- Low urban density — small towns, trailer parks, roadside diners rather than skyscrapers
- Water-heavy terrain — rivers, marshes, bayous, and potentially airboat-navigable waterways
- Wildlife-rich — alligators, birds, and the kind of fauna you don't find in Vice City
- A natural hub for rural crime — meth operations, poaching, illegal dumping, back-country chases
Rockstar has confirmed Grassrivers as a region name. The specific gameplay systems and mission types within it have not been officially detailed. The above characterization is informed inference based on the region's name and its clear real-world analog.
Grassrivers and Real Florida
The Everglades is the largest subtropical wilderness in the United States — 1.5 million acres of protected wetland. A fictional version in GTA 6 would need to be compressed relative to reality, but even a condensed Everglades-style region would provide substantial swamp and river terrain for exploration, missions, and environmental storytelling.
Small communities in real Florida's Everglades region — Everglades City, Chokoloskee, Ochopee — are deeply specific in character: fishing communities, stone-crab operations, back-country guides, and the occasional very old money land baron. Any towns within Grassrivers likely draw on this community type. Their specific names are not confirmed by Rockstar.
Port Gellhorn: The Working Port
Port Gellhorn is the most industrially explicit region name in Leonida. "Port" in the name signals a significant waterfront and shipping economy. The "Gellhorn" designation suggests a proper city or large town rather than a generic port facility — implying a real urban center with its own identity, distinct from Vice City's glamour.
Florida's working-class port cities provide the real-world template here. Cities like Port St. Lucie, Fort Pierce, or the industrial corridors around Jacksonville or Tampa all share a profile: working waterfront, significant cargo infrastructure, a population employed in trades and logistics, and a criminal ecosystem that centers on what moves through those ports.
For GTA gameplay, Port Gellhorn is a natural setting for:
- Cargo heists — stealing from shipping containers or in-transit trucks
- Smuggling operations — the port as a pipeline for contraband moving into Leonida
- Blue-collar criminal networks — unions, dock workers, organized crime with roots in labor
None of the above is confirmed mission content. It's the structural logic of what a port city setting enables in a GTA game, clearly labeled as inference and speculation.
Port Gellhorn's Role in Leonida's Economy
Within Leonida's fictional geography, Port Gellhorn likely serves as the state's primary industrial hub — the working machinery beneath Vice City's glamour. This is a relationship that mirrors real Florida, where cities like Miami depend heavily on Port of Miami operations that most tourists never see. Port Gellhorn presumably provides the economic grunt work that Vice City's service economy consumes.
Ambrosia: The Most Mysterious Region
Ambrosia is the least detailed of GTA 6's six confirmed regions. The name itself is intriguing — "ambrosia" in mythology is the food of the gods, something associated with sweetness, pleasure, and a certain decadent excess. In American regional parlance, ambrosia salad is a Southern potluck staple. Either reading suggests a region with a sweeter or more indulgent character than Port Gellhorn's industrial grit.
What Rockstar has not confirmed: Ambrosia's geography, size, primary character, named communities, or gameplay focus. It is, at this point, the most blank-slate of the confirmed regions.
Speculation in the community ranges widely. Some believe Ambrosia could be a wealthy enclave — a Palm Beach analog, perhaps — with gated communities, country clubs, and old money. Others suggest it could be a resort area or a developed tourist destination distinct from the Keys. A third theory positions it as a college town or arts community.
All of these are fan speculation. We'll flag this section clearly as unverified territory and update the moment Rockstar provides official detail.
How These Three Regions Fit the Bigger Picture
Grassrivers, Port Gellhorn, and Ambrosia together occupy a substantial portion of Leonida's confirmed geography. They provide the rural, industrial, and enigmatic counterweights to Vice City's urban glamour, the Keys' tropical escape, and Mount Kalaga's wilderness edge.
Rockstar's confirmed track record — Red Dead Redemption 2's richly detailed rural America, GTA 5's blend of city and Blaine County — suggests these non-urban regions won't be afterthoughts. The studio has consistently used non-city environments to tell stories that the city itself can't accommodate: poverty, isolation, rural corruption, and the kind of quiet desperation that makes Vice City's neon look almost obscene by contrast.

The Bottom Line
Grassrivers, Port Gellhorn, and Ambrosia are three of GTA 6's six confirmed regions, and each one suggests a distinct slice of Leonida's identity — swamp country, industrial waterfront, and something altogether more mysterious. The specifics of their missions, towns, and gameplay systems remain officially undetailed, but their existence alone confirms that Rockstar has built a state with genuine geographic and cultural range. Leonida isn't just Vice City with a big backyard. It's a full state, and the November 19, 2026 release will be the proof.
