Map and Regions
Grand Theft Auto VI takes place across the state of Leonida, a fictional version of Florida. The map is estimated to be roughly 2 to 2.5 times the size of GTA V's map of San Andreas. Six major regions have been confirmed through official trailers, the Rockstar website, and accompanying screenshots.
Counties
Leonida is divided into multiple counties visible on in-game maps and license plates shown in trailers. Confirmed county names include Vice-Dale (containing Vice City), Kelly (containing Port Gellhorn), Leonard, Ambrosia, and Mariana. The county structure suggests a level of administrative world-building beyond the simple neighborhood boundaries of previous GTA games.

Vice City (Vice-Dale County)
Vice City is the game's primary urban center, a sprawling modern-day metropolis inspired by Miami. It sits within Vice-Dale County. For a detailed breakdown of Vice City's districts, landmarks, and enterable locations, see the dedicated Vice City article.
The city is dense and vertical by GTA standards, with Art Deco high-rises, beachfront hotel strips, and distinct neighborhoods each with their own character. It is the cultural and commercial heart of Leonida.
Leonida Keys
The Leonida Keys are an archipelago of tropical islands at the southern tip of Leonida, inspired by the Florida Keys. This is where Jason Duval's story begins, as he works for drug runners operating from the islands.
The Keys feature crystal-clear tropical waters, coral reefs for diving, island bars, and boat docks. The area has a laid-back, maritime atmosphere contrasting sharply with Vice City's urban intensity. Underwater exploration and diving are primary activities in this region.
Grassrivers
Grassrivers is a vast wetland region in the southwestern part of Leonida, inspired by the Florida Everglades. The area features dense mangrove forests, shallow waterways navigable by airboat, and thick vegetation. Alligators roam throughout the region, and flamingos are visible in the shallows.

The region appears sparsely populated, with scattered fishing camps, wildlife observation points, and small communities along the waterways. Airboats (fan boats) are the primary mode of transportation here.
Port Gellhorn (Kelly County)
Port Gellhorn sits within Kelly County and is described as a decaying coastal resort town with a heavy undercurrent of crime. The area has a run-down, once-prosperous feel, with shuttered businesses, cheap motels, and industrial waterfront areas. It contrasts with Vice City's glamor and the Keys' paradise-like atmosphere.
The criminal element in Port Gellhorn appears more blue-collar and desperate compared to Vice City's organized crime. Trailer footage shows working-class neighborhoods, dive bars, and deteriorating infrastructure.
Ambrosia (Ambrosia County)
Ambrosia is a rural and industrial region in the northeastern part of Leonida, inspired by inland Florida. The area features sugar cane refineries, agricultural land, biker culture, and proximity to Lake Leonida, a large central freshwater body. The county has a very different feel from coastal Leonida, with more open roads, farmland, and small-town settings.
Mount Kalaga National Park
Mount Kalaga is a forested national park in the northern part of Leonida, inspired by Florida's state and national forests. The area provides a wilderness setting with dense tree cover, river systems, and wildlife including deer and panthers.

Rockstar's official website confirms hunting and fishing as activities at Mount Kalaga. Kayaking along the park's rivers is also shown in Trailer 2. The park represents the most rural and natural environment in the game.
Lake Leonida
Lake Leonida is a large freshwater body visible in the interior of the state, near Ambrosia County. It is inspired by Florida's Lake Okeechobee. The lake appears in aerial shots from the trailers and is a geographic boundary between the urban coastal regions and the rural interior.
Gloriana State Reference
License plates visible in Trailer 2 reference "Gloriana State," which has led to speculation about a second explorable state possibly inspired by Georgia. Rockstar has not confirmed whether Gloriana is accessible in the game or simply a detail on imported vehicles. This remains unverified.
