Not all of Leonida is neon and beaches. The Grassrivers is GTA 6's version of the Everglades — a vast, humid expanse of wetlands, mangroves, and slow-moving water that feels a world away from Vice City's glamour.
If Vice City is the state's glossy face, the Grassrivers is its wild, lawless backcountry.
What the official media shows
From Rockstar's trailers and screenshots, the Grassrivers is characterized by:
- Airboats and waterways: Flat-bottomed swamp boats built for gliding across shallow marshland.
- Wildlife: Alligators are front and center — a signature of this ecosystem.
- Off-grid characters: Sun-baked swamp locals who look right at home in this remote, humid frontier.
It's the kind of environment that gives GTA 6's Leonida real variety — a natural, untamed region sitting alongside dense city streets and island chains.
Why Grassrivers matters
Rockstar's Leonida is reported to be roughly twice the size of GTA V's map, and regions like the Grassrivers are a big reason why. They expand the world beyond the urban core into distinct, atmospheric biomes.
A word of caution on the details: specific missions, activities, or named locations inside the Grassrivers have not been confirmed. What we can say for certain is that this swampland is one of Leonida's named regions and a striking change of pace from the city.
GTA 6 launches November 19, 2026 on PS5 and Xbox Series X|S. We'll update this guide as Rockstar confirms more about what the Grassrivers holds.
