Grassrivers

Grassrivers is the great wetland of Leonida. Rockstar calls it the untamable jewel of the state's crown, a primordial landscape of swamps and mangroves, and introduces it under the heading “Welcome to the Wetlands“.

Gators are the most famous attraction. Rockstar hints, however, that deadlier predators and stranger discoveries are waiting among the mangroves, without saying what exactly that means.

What is officially known

• A wetland region of swamps and mangroves in Leonida

• Known for its alligators

• Rockstar mentions deadlier predators and stranger discoveries

• Official screenshots show airboats, a police chase through the swamp and the Vice City skyline in the distance

Grassrivers in official images

Rockstar has published six screenshots and a postcard artwork of Grassrivers. The official descriptions include two people in an airboat surrounded by alligators and a chase in which a helicopter and two police cars pursue a pickup truck through the swamp. Another shot shows three mud-covered people posing on an airboat with a dead alligator and a wildcat, and one more follows a speedboat toward buildings on piers with the Vice City skyline in the distance.

Grassrivers is one of the six regions featured on Rockstar's Only in Leonida page, together with Vice City, the Leonida Keys, Port Gellhorn, Ambrosia and Mount Kalaga National Park. Like the others, it has its own official postcard in the Artwork & Wallpapers section.

Rockstar has not released an official map yet. On November 19, 2026, Rockstar plans to add an official printable cover-art poster and a map of Leonida as a free digital download on its official site. A community-made map is available on our interactive map page.
