GTA 6 Map Guide: Leonida's Six Regions and Vice City

The map questions arriving from search split into two very different ones: what is on the map, and how big it is. This page handles the first. The second has its own set of developer comparisons and a lot of invented square mileage, which the map size breakdown takes apart.

Leonida is a state, not a city

The setting is the fictional state of Leonida, built as a Florida analogue, and Vice City is its headline city rather than the whole world. That structure is a departure from GTA 5, where Los Santos sat inside a single state with a large amount of empty land between towns. Leonida is organised as a flagship city plus five surrounding regions, each with its own character and its own named locations.

Rockstar’s own site lists the six: Vice City, the Leonida Keys, Grassrivers, Port Gellhorn, Ambrosia and Mount Kalaga. Those are the names to use when you are looking for anything else, because they are the labels Rockstar attached to the world rather than fan shorthand.

What each region suggests

Vice City is the dense urban core, the neon-and-pastel piece the trailers lean on hardest. The Leonida Keys are the island chain to the south, which is where the smuggling backstory lives — Brian Heder’s boat yard sits there. Grassrivers reads as wetland and airboat country, and Rockstar’s radio material has a country station reporting from it. Port Gellhorn, Ambrosia and Mount Kalaga fill out the industrial, small-town and elevated terrain the state needs to not feel like one city with a motorway attached.

Vice City against Los Santos

Rockstar North co-studio head Rob Nelson gave journalists a set of comparisons during the August 2026 preview round, and the city-level one is the easiest to picture: Vice City alone is about twice the size of Los Santos, and once its surrounding built-up area is counted, that footprint is roughly eleven times larger than Los Santos and its outskirts.

The eleven-times figure is the one that changes how the map plays. It says the growth is concentrated in city, not in countryside you drive through once. Aaron Garbut repeated the headline comparison in Game Informer’s September 29 issue, describing Leonida as about twice GTA 5’s map and the largest Rockstar has built.

Density is the claim, not area

Preview reporting from the same round describes a very large number of enterable interiors — shops, lobbies, rooftops — and notes that story locations stay open after their missions finish. Roads were reportedly drawn about fifteen per cent narrower than GTA 5’s to make streets feel tighter, and the animation count was put at more than 600,000 unique animations against roughly 55,000 in GTA 5.

The Extended Look shows the density directly: street-level foot traffic, working traffic systems, jet skis, scuba diving and basketball courts away from missions. All of that is observation of an official video rather than a feature list Rockstar published.

What the map still hides

How much of Leonida is playable rather than backdrop is unanswered, and so is travel time between the Keys and Mount Kalaga. Rockstar has never released a top-down map, so every labelled map in circulation is a reconstruction. For the pieces that are settled — date, platforms, price — the confirmed information page keeps the official half separate from the guesses.
