GTA 6 Map Explained: Every Region Rockstar Has Confirmed

Rockstar Games and the Game Informer cover story it partnered on have officially confirmed six named regions inside GTA 6's fictional state of Leonida — Vice City, the Leonida Keys, Grassrivers, Port Gellhorn, Ambrosia, and Mount Kalaga National Park — and Rockstar's own developers have described the overall map as roughly twice the size of GTA 5's Los Santos and Blaine County. Beyond that, Rockstar has not published an exact square-mile figure for either game, and anything claiming a precise number for GTA 6 right now is an outside estimate, not a Rockstar statement.

What Rockstar has actually confirmed about the map

Rockstar's own official GTA VI site keeps its public-facing copy deliberately sparse: it confirms the game is set "across the state of Leonida," with the story centered on "Vice City, USA," and includes a "People & Places: Only in Leonida" section pointing at the wider world beyond the city. For the detailed geography, Rockstar partnered directly with Game Informer, which published a dedicated feature naming and describing six major areas of the map after visiting Rockstar and talking to its developers. That feature, and the magazine's follow-up September 2026 cover story — whose 14-page digital issue went live on September 29, 2026 — remain the most detailed on-the-record sources for Leonida's geography anywhere outside Rockstar's own walls. If you want the news-angle version of that same cover story — the screenshots, the wildlife counts, the weather system — our breakdown of the Game Informer cover story covers it in full; this piece focuses specifically on the map itself.

Taken together, the confirmed geography breaks down into six named regions. Here's what Rockstar and Game Informer have said about each one, with nothing added beyond what's been published.

Vice City

Vice City is the obvious centerpiece and the only location Rockstar's own marketing site names directly and repeatedly. Rockstar's copy calls it "the sun and fun capital of America" and "the darkest side of the sunniest place in America," and in its six-major-areas feature, Game Informer described it as capturing "the glamour, hustle, and greed of America... in a single city," calling out named sub-areas including Ocean Beach, Little Cuba, the Tisha-Wocka flea market, and the VC Port. It's Rockstar's fictionalized take on Miami, and — as with the original 1986-set Vice City in GTA Vice City and its mentions since — it functions as the series' long-running Florida analog, now rebuilt as the hub of a much larger state.

Vice City isn't a new name for the franchise — it first appeared as the primary setting of 2002's Grand Theft Auto: Vice City, a 1980s-set game built on a much smaller version of the same Miami-inspired concept, and it has been referenced or revisited in spin-off and handheld entries since. According to Wikipedia's entry on Grand Theft Auto VI, the new game rebuilds Vice City as part of a present-day, far larger Leonida rather than reusing the original map, which is consistent with Rockstar's confirmed framing of the city as the hub of a six-region state rather than a standalone map the way it was in 2002. That context matters for scale expectations: this is a full modern rebuild of a historically smaller setting, not a direct port, and Rockstar has given no indication that it is reusing any of the older game's geography.

Leonida Keys

Described by Game Informer as a tropical island chain parodying the real Florida Keys, the Leonida Keys were confirmed as "a beachside tropical paradise, complete with retirees, casual boating, and sea turtles" — alongside a line about the surrounding waters being among the most dangerous in the game. It's the laid-back, rural counterpart to Vice City's density, built around an archipelago rather than a single landmass.

Grassrivers

Grassrivers is Rockstar's version of the Everglades: a swampy wetland region that Game Informer's reporting describes as home to alligators and, in Rockstar's own phrasing, "far deadlier predators" than the wildlife alone — a nod to armed residents living off the grid in the marshland. No further geographic detail (size, number of towns, connecting roads) has been published for this region yet.

Port Gellhorn

Port Gellhorn is confirmed as a declining coastal town — Game Informer's language calls it a place where "stores have been abandoned and its parking lots are filled with malt liquor, painkillers, and truck stop energy drinks." It reads as the state's economically depressed, "forgotten coast" counterpoint to Vice City's glamour: seedy motels, faded attractions, and an implied criminal underbelly.

Ambrosia

Ambrosia sits inland and has been described by Rockstar and Game Informer as the "heart of Leonida" — an industrial-and-agricultural region defined by "old school values," farming and refinery operations, and the watchful presence of a local biker gang. It's the one confirmed region that isn't coastal, suggesting Leonida's map extends well beyond its beaches and keys.

Mount Kalaga National Park

Mount Kalaga is the confirmed wilderness region at the northern edge of the map, offering what Rockstar's materials describe as "prime hunting, fishing, and off-road trails." Game Informer's reporting adds that Mount Kalaga sits on the boundary with Gloriana, described as Leonida's neighboring state and the game's version of the real-world Florida–Georgia line — making it, so far, the only confirmed reference to anything existing beyond Leonida's own borders, even though Gloriana itself has not been detailed as a playable region.

Weather, wildlife, and what they signal about the map

Two other confirmed details help fill in the picture of how the map is meant to function, even without a size figure attached. Game Informer's coverage, drawn from its licensed access to Rockstar, confirms that Leonida is home to more than 170 animal species — described as a mix of the real Florida region's native and invasive wildlife — living across its land, skies, and waters. The same coverage confirms a dynamic weather system built to simulate the real unpredictability of Florida's climate, including tropical storms and hurricanes capable of affecting Vice City and the surrounding regions. Neither detail is a size measurement, but both point toward a map designed around ecological and environmental variety across its six named regions rather than a single repeated biome, which lines up with the contrast between a swamp (Grassrivers), a mountainous wilderness (Mount Kalaga), an archipelago (the Leonida Keys), and dense urban blocks (Vice City) all being confirmed as distinct, named parts of the same state.

How Leonida compares to GTA 5's map

This is where the honesty has to be explicit: neither Rockstar nor Take-Two has ever published a hard square-mile or square-kilometer figure for GTA 5's combined Los Santos and Blaine County map, and the same is true for GTA 6's Leonida so far. The oft-cited "49 square miles" or "127 square kilometers" figures for GTA 5 that circulate across gaming wikis and forums are independent, fan-calculated estimates — not numbers Rockstar itself has confirmed, and this article is not treating them as such.

What is on the record is a direct comparison from Rockstar's own developers. Rockstar North art director Aaron Garbut told Game Informer, in the magazine's licensed September 2026 cover story, that Leonida's map is roughly twice the size of the one in GTA 5, and described it as the studio's largest built to date. That's a relative claim about scale, not an absolute measurement, but it's the clearest official sizing statement available right now.

In practical terms, the six confirmed Leonida regions already outnumber the two broad named areas most players associate with GTA 5, which lines up with the "roughly twice the size" comment even without a hard number attached to it.

What's still rumor, not confirmed

Because GTA 6 is one of the most leaked games in recent memory, it's worth being direct about where the official record stops. Rockstar and Game Informer have not published an exact map size in square miles or kilometers for Leonida. They also have not confirmed a total number of cities or towns beyond the six named regions above, a map of Gloriana as a playable area, or any specific borders, road layouts, or square-footage breakdowns of Vice City itself. Numbers claiming an exact size (for example, specific multiples of Red Dead Redemption 2's map) that circulate on fan wikis, leak-aggregation sites, and social media should be treated as unverified unless Rockstar or a licensed outlet like Game Informer attaches a name and a direct quote to them. This article only reports what carries that attribution.

Why the map matters for how GTA 6 plays

Rockstar's narrative team has already set expectations that the story won't tour every inch of Leonida — the studio has said plainly that it doesn't have time to take players everywhere the map offers. That's consistent with how GTA 5 handled Blaine County: large stretches of rural map existed primarily for side content, exploration, and multiplayer rather than every mission thread. With six distinct, named regions instead of two broad ones, Leonida appears to be designed explicitly around that kind of optional sprawl — a swamp region, a depressed port town, an inland industrial belt, and a national park all exist, on the public record, specifically as places the main story may only partially use.

Per Wikipedia's overview of Grand Theft Auto V, that game's Blaine County was built as open countryside surrounding the dense city of Los Santos, giving players a deliberate contrast between urban missions and rural, vehicle-heavy traversal. Leonida's six confirmed regions suggest Rockstar is multiplying that same idea rather than abandoning it: instead of one city and one countryside, the confirmed geography points to one city (Vice City), one archipelago (the Leonida Keys), one wetland (Grassrivers), one depressed coastal town (Port Gellhorn), one inland industrial belt (Ambrosia), and one mountain wilderness (Mount Kalaga) — each apparently built as its own distinct traversal experience rather than a variation on the last.

None of this is a confirmation of total square mileage, and readers should treat it as exactly what it is: a structural comparison based on confirmed region counts and developer commentary, not a measured area.

What's next for Leonida's map

Rockstar has not announced any further scheduled reveals specifically about Leonida's geography, and the studio's standard pattern — as with GTA 5 — is to keep withholding a full interactive map until much closer to, or after, launch. With GTA 6 currently dated for November 19, 2026 on PlayStation 5 and Xbox Series X|S — as logged on Wikipedia's GTA VI entry alongside its own sourcing — expect any additional official region names, connecting roads, or size detail to come either through Rockstar's own newswire updates or through further licensed previews along the lines of the Game Informer cover story. For logistics rather than geography — price, editions, and pre-order specifics — our GTA 6 release date and pre-order guide covers what's confirmed on that side separately. We'll update this explainer if Rockstar or a licensed partner publishes anything further on Leonida's size or borders.
