Leonida explained: Vice City, Leonida Keys, Grassrivers, Port Gellhorn, Ambrosia and Mount Kalaga

As of October 27, 2026. Grand Theft Auto VI is set in Leonida, a fictional US state. On its official Only in Leonida page, Rockstar Games introduces six destinations: Vice City, the Leonida Keys, Grassrivers, Port Gellhorn, Ambrosia and Mount Kalaga. Rockstar calls them a few of the state's must-see places, so they are not presented as a complete list.

According to the Trailer 2 synopsis, the criminal conspiracy that Jason and Lucia get caught up in stretches across the entire state. Below is a summary, in our own words, of what Rockstar writes about each place.

The six places at a glance

Vice City is the state's big city. Rockstar presents it as the place where American glamour, ambition and greed come together. The 1980s are long gone, yet the city still sees itself as the nation's capital of sun and fun. Named spots include Ocean Beach with its pastel art deco hotels, Little Cuba and its busy bakeries, the Tisha-Wocka flea market known for knock-off brands, and the VC Port, which Rockstar bills as the cruise ship capital of the world.

The Leonida Keys are a chain of tropical islands. Rockstar paints an unpretentious, easygoing life with a casual dress code and well-stocked bars. Just off the shore, however, begin some of the most beautiful and most dangerous waters in America. Jason Duval's character profile says he works for local drug runners in the Keys.

Grassrivers is an ancient-looking expanse of swamp and mangrove forest that Rockstar calls “the untamable jewel of Leonida’s crown.” Alligators are its most famous residents. Among the mangroves, though, Rockstar hints at deadlier predators and odder discoveries.

Port Gellhorn is described as Leonida's forgotten coast. Once a popular holiday destination, it is now an area of budget motels, closed attractions and deserted strip malls. Rockstar says a new economy has taken hold there, fueled by malt liquor, painkillers and energy drinks from truck stops.

Ambrosia lies at the center of the state. Industry and traditional values still rule here, whatever the price. Most jobs come from the Allied Crystal sugar refinery, while a local biker gang supplies nearly everything else, according to Rockstar.

Mount Kalaga is a national landmark near Leonida's northern border. Rockstar promotes it for hunting, fishing and off-road trails. The dense woods around it are home to hillbilly mystics and paranoid radicals who prefer to stay out of the government's sight.

What is still open

Rockstar has not shared the size of the game world or a full list of regions. There are only a few hints about where places lie, such as Ambrosia in the heart of the state and Mount Kalaga on its northern border. It is also unknown whether every area is accessible from the start. A secondary report on the summer 2026 press preview relays an attending YouTuber's account that Leonida is roughly three times the size of the Red Dead Redemption 2 world. These are second-hand accounts, and there is still no official size figure.

All officially named places, with sources, are collected in our locations database. More context on the game world is available on the map page.
