GTA 6 Map Size and All 6 Regions of Leonida

The scale of Grand Theft Auto VI is no longer something fans have to estimate based on trailers and fan-made maps alone. According to Game Informer, the GTA 6 map is approximately twice the size of GTA 5's map. Rockstar is promising more than just a massive playable area, with six distinct regions, dynamic weather systems, and over 170 animal species bringing Leonida to life.

These new details emerged on September 29, 2026, in Game Informer's special coverage of GTA 6. Here's everything we know about the size of Leonida, its six regions, and what makes this open world different from previous GTA games.

How Big Is the GTA 6 Map Compared to GTA 5?

One of the biggest questions surrounding the game is how the GTA 6 map size compares to its predecessor.

In an interview with Game Informer, Rockstar's Aaron Garbut confirmed that GTA 6's playable world is approximately twice as large as GTA 5's map. According to Garbut, Leonida will be the largest game world Rockstar has ever created.

However, size isn't the only improvement. The developers have also focused on environmental density, including buildings, rooftops, alleyways, interiors, and countless small details that make cities feel more realistic.

GTA 6 Map Size in Square Miles

Rockstar has not yet revealed the exact size of Leonida in square miles or square kilometers.

However, Forbes contributor Brian Mazique provided an estimated comparison:

• GTA 5: Approximately 29.3 square miles (75.9 km²).

• GTA 6: Approximately 58.6 square miles (151.8 km²).

• Difference: Roughly twice the total map area.

Important: The 58.6-square-mile figure is an estimate published by Forbes on October 6, 2026, not an official measurement from Rockstar Games. It was calculated by doubling the estimated size of GTA 5's map. The actual playable area may differ.

Even without exact measurements, one thing is clear: players will have significantly more territory to explore than Los Santos and Blaine County offered in GTA 5.

All 6 Regions of GTA 6's Leonida Map

GTA 6 takes place in the fictional American state of Leonida, which is heavily inspired by Florida. Unlike GTA 5, which primarily focused on Los Santos and its surrounding countryside, the new game features six major regions with distinct environments and atmospheres.

Vice City

Vice City returns to the GTA franchise on an entirely new scale. Inspired by Miami, the city features neon-lit streets, beaches, skyscrapers, luxury neighborhoods, and a vibrant nightlife scene.

This is where Rockstar's improvements to urban density and environmental detail are expected to stand out the most. However, Vice City is now just one part of a much larger state rather than the entire setting.

Leonida Keys

Leonida Keys is a chain of tropical islands inspired by the real-world Florida Keys.

Turquoise waters, long bridges, coastal highways, and small island communities create an ideal environment for exploring by car or boat.

The region is particularly interesting for water-based activities, including scuba diving, jet skiing, and coastal exploration.

Grassrivers

Grassrivers is Leonida's fictional version of the famous Florida Everglades.

Here, urban landscapes give way to wetlands, dense vegetation, and winding waterways. Alligators and other wildlife inhabit the region, creating a completely different atmosphere from the busy streets of Vice City.

Airboat travel and exploring remote areas are expected to play an important role in discovering this part of the map.

Port Gellhorn

Port Gellhorn represents the less glamorous side of Leonida.

This coastal region features budget motels, aging tourist attractions, local bars, and the atmosphere of small-town America.

Compared to the luxury and nightlife of Vice City, Port Gellhorn offers a striking contrast and highlights the environmental diversity of GTA 6.

Ambrosia

Ambrosia introduces players to Leonida's industrial side.

Factories, working-class neighborhoods, and biker culture shape the region's identity, creating an atmosphere far removed from the state's tourist beaches.

Here, Rockstar focuses on another side of American life, including smaller communities, industrial development, and local criminal activity.

Mount Kalaga National Park

Mount Kalaga National Park is located in northern Leonida, near the border with the fictional state of Gloriana.

The region features forests, nature trails, and rural landscapes. Activities include ATV riding, mountain biking, fishing, and off-road adventures.

It's one of the locations that stands out most from the traditional urban environments associated with the GTA franchise.

More Than 170 Animal Species in GTA 6

The size of the map is only one part of GTA 6's ambitious open world.

According to Game Informer, GTA 6 will feature more than 170 animal species, including over 60 bird species, more than 30 terrestrial mammal species, as well as various fish and reptiles.

Some of the wildlife players can expect to encounter includes:

• Alligators and manatees.

• Flamingos and pelicans.

• Sharks and whales.

• Various other birds, fish, and land animals.

Animals are divided into Rare, Discoverable, and Legendary categories, giving players additional reasons to explore Leonida beyond the main storyline.

It will be particularly interesting to see how this wildlife interacts with different environments, from the swamps of Grassrivers to the coastal waters of Leonida Keys.

Dynamic Weather, Hurricanes and More Activities

Rockstar has also confirmed an expanded dynamic weather system featuring tropical storms and hurricanes.

Weather conditions will vary by location. While one part of Leonida experiences heavy rainfall, another region may have completely different conditions.

The new wind simulation system affects water, vegetation, character hair, and environmental objects, making travel between regions feel more immersive.

Beyond weather and wildlife, GTA 6 will offer numerous activities, including kayaking, scuba diving, BASE jumping, pool, mini-golf, street racing, off-road racing, gym visits, and zoos.

Importantly, completing the main storyline won't require players to visit every corner of Leonida. Large parts of the map will remain available for optional exploration.
