Leonida's most important map feature is not a rumored square-mile total. It is contrast. Rockstar has built the reveal around six environments with different people, movement patterns and economic pressures. Comparing those regions shows what the official material actually promises: a world that changes character as the story leaves Vice City's polished coastline.
Status: the six region names are confirmed on Rockstar's Only in Leonida page (re-read 28 September 2026). The descriptions in the table below were recorded from Rockstar's region profiles on 8 August; the profile pop-ups did not load on 28 September, so they are not re-verified. Rockstar's Ultimate Edition text also names Washington Beach, Watson Bay, Gambit Bay, Stockyard, Lake Leonida and Mount Kalaga; official screenshot titles: Vice City 12, Leonida Keys 6, Port Gellhorn 6, Ambrosia 6, Grassrivers 6, Mount Kalaga 6.
This guide compares only published descriptions and careful visual observations. “Traversal evidence” means a vehicle or environment is visible in official media; it does not automatically confirm a purchasable business, race series, side activity or unrestricted free-roam system.
Six-Region Comparison
| Region | Identity (recorded 8 Aug) | Published evidence (recorded 8 Aug) | Traversal signal | Still unknown |
|---|---|---|---|---|
| Vice City | Dense coastal metropolis | Ocean Beach, Little Cuba, Tisha-Wocka, VC Port | Urban travel, nightlife and waterfront movement | District boundaries and interior count |
| Leonida Keys | Tropical island chain | Bars, local settlements, dangerous waters | Boats, seaplanes and marine environments | Island count and bridge layout |
| Grassrivers | Primordial wetlands | Mangroves, alligators and unusual wildlife | Airboats and water-heavy traversal | Named towns and activity systems |
| Port Gellhorn | Declining former resort coast | Motels, closed attractions, strip malls, dirt bikes | Roadside and dirt-bike travel | Port jobs and shipping systems |
| Ambrosia | Industrial heartland | Allied Crystal refinery and biker influence | Rural roads and industrial spaces | Business ownership and economy mechanics |
| Mount Kalaga | Northern national park | Hunting, fishing, off-road trails, backwoods | Off-road exploration | Park size, summit height and survival systems |

Vice City vs the Rest of Leonida
Vice City is the commercial and cultural center of the reveal. It has named neighborhoods, cruise infrastructure, music-industry characters and the strongest concentration of polished urban imagery. The other five profiles widen the state in deliberate steps: islands, wetlands, a faded tourism coast, industrial country and a northern wilderness.
That structure matters for pacing. A city can deliver dense traffic, crowds and short-distance variety; rural regions can create longer journeys, visibility changes and different vehicle choices. Those are design implications rather than confirmed mechanics. Rockstar has not published drive times, mission distribution or the order in which regions become accessible.
Leonida Keys vs Grassrivers
Leonida Keys
Open coastal water, settled islands and leisure culture. Official images foreground boats, a seaplane and marine life, while Rockstar warns that the surrounding water is dangerous.
Grassrivers
Confined wetland channels, mangroves and wildlife pressure. The visual language favors airboats and shallow water instead of the Keys' open-sea movement.
Both regions are water-led, but they solve different world-design problems. The Keys connect settlements across open water; Grassrivers turns water into terrain. Claims about diving treasures, airboat races, fishing economies or wildlife rewards must wait for explicit gameplay documentation.
Port Gellhorn vs Ambrosia
These profiles are often flattened into one “industrial” category, but Rockstar describes different forms of decline and control. Port Gellhorn is a former vacation destination whose old tourist economy has collapsed. Its identity comes from motels, dead attractions, strip malls, stimulants and dirt bikes. Ambrosia is productive rather than abandoned: the Allied Crystal refinery supplies jobs while a biker gang shapes the surrounding informal economy.
Why Mount Kalaga Is the Clearest Activity Region
Mount Kalaga is the only region profile that directly names a compact activity set: hunting, fishing and off-road trails. That does not reveal controls, rewards, licenses, animal inventories or race formats, but it moves those activities beyond visual speculation. The national park's position at the northern border also gives it the clearest official directional relationship in Leonida.
Rockstar also places mystics and anti-government radicals in the surrounding backwoods. That establishes population and tone. It does not confirm paranormal encounters, a cult questline, an observatory, abandoned mines or a survivalist property system, all details previously presented too confidently across fan guides.
How to Choose the Right Region Guide
Leonida Regions FAQ
How many GTA 6 regions has Rockstar confirmed?
Rockstar's Only in Leonida material profiles six: Vice City, Leonida Keys, Grassrivers, Port Gellhorn, Ambrosia and Mount Kalaga National Park.
Which GTA 6 region has confirmed hunting and fishing?
Mount Kalaga's official profile explicitly names hunting, fishing and off-road trails. That is stronger evidence than inferring activities from wildlife or scenery elsewhere.
Is Port Gellhorn GTA 6's main industrial port?
Rockstar characterizes Port Gellhorn as a faded vacation coast with motels, closed attractions, strip malls and dirt-bike culture. VC Port is separately described as a cruise-ship center. A large container-port simulation is not announced.
Where is Ambrosia in GTA 6?
Rockstar places Ambrosia in the heart of Leonida and Mount Kalaga at the northern border. Exact map coordinates, distances and county boundaries remain unpublished.
Which GTA 6 region should players explore first?
Rockstar has not published free-roam progression or regional locks. The best answer depends on the final story structure; current material only identifies each region's theme and visible traversal opportunities.
