Grassrivers is GTA 6’s wetland region, inspired by Florida’s Everglades and one of the wildest parts of Leonida. Here is what Rockstar described and what has appeared so far.
Everything we know about Grassrivers →
Quick facts
- Inspiration: the Everglades
- Type: swamps, mangroves and rivers
- Activities seen: airboats, fishing and kayaking
- Wildlife: gators and other predators
What Rockstar says about Grassrivers
“The untamable jewel of Leonida’s crown. You never know what lies beneath the surface of this primordial expanse.”
Rockstar Games
According to the official description, gators are the famous attraction, but the mangroves hide far deadlier predators.
What we have seen
- Airboats cutting through the swamp
- A bird-watching observation tower
- According to previews, fishing and kayaking are among the activities
Grassrivers on the radio
Back Country Radio broadcasts to the Grassrivers, Port Gellhorn and beyond. One of its characters, Mud Dog Mike, is a roving reporter and swamp meteorologist who reports from his airboat.
What we still don’t know
Rockstar has not revealed which missions take place in the swamps or which animals besides gators live there.
The official description, word for word
The official tagline is “Welcome to the Wetlands”, and Rockstar’s text is short and menacing:
“The untamable jewel of Leonida’s crown. You never know what lies beneath the surface of this primordial expanse.” / “The gators may be the most famous attraction, but there are far deadlier predators and weirder discoveries among the mangroves.”
Official Rockstar Games region description, published on the GTA VI site on May 6, 2025.
Read what Rockstar is actually saying: the gators are not the real danger. It uses the most obvious animal as bait and then warns you the problem is something else. What those “far deadlier predators” and “weirder discoveries” are has not been revealed.
What the official screenshots show
In the official May 6, 2025 drop, Grassrivers got 4 images (GamesRadar counted 5 in the extended set). And what they show is not ecotourism:
- Gator hunters armed with assault rifles, on airboats
- A police chase through swamp water
- Live alligators
- Wetland terrain and mangroves
It is the region with the sharpest contrast between its description (“untamable jewel”) and its imagery — people with rifles standing on a boat.
What Game Informer confirmed
In issue 382 (September 2026), Rockstar went further:
- Grassrivers is Leonida’s version of the Everglades: a large wetland with abundant wildlife, including dangerous reptiles
- Air boating is on the official open-world activity list. Rockstar did not literally say “in Grassrivers”, but the official airboat screenshots are from the region
- The wind system moves the swamp grass — an environmental detail built specifically for this region
- One swamp screenshot was captioned as “probably” from this region
In the August 2026 Extended Look, GamesRadar described boating through a swamp in the activity reel, and in the launch trailer Jason wades through swamp water with company. Hunting and fishing did not appear in the Extended Look — PC Gamer noted that absence explicitly, so do not count it as shown.
The real-world inspiration: the Everglades
Alongside Miami, this is the most solid match of the six regions. The official description uses “wetlands”, “mangroves” and “gators”, and Rockstar confirmed to Game Informer that the team spent research days in the Everglades.
Dexerto notes the region is clearly heavily inspired by the Everglades without being an exact recreation — and flags an interesting departure: the game’s version has far more inhabitants than the real area.
One hook worth citing as editorial reading, not confirmation: “Grassrivers” echoes “River of Grass”, the phrase that became the Everglades’ defining description after Marjory Stoneman Douglas’s 1947 book The Everglades: River of Grass. Rockstar never confirmed the reference, but the translation is too literal to be accidental.
Wildlife: what Rockstar promised
Leonida has over 170 species, some never seen in a Rockstar game: 60+ birds, 30+ land mammals, plus fish and reptiles. Confirmed natives include alligators, flamingos, pelicans and manatees.
The most authentically Floridian detail is the list of confirmed invasive species: green iguanas, cane toads, feral cats, nine-banded armadillos and rhesus macaques. All are real Florida invasives — the rhesus macaques genuinely do run wild there, around Silver Springs.
Technically: some animals are iridescent, translucent or bioluminescent; birds have distinct feather types; and a new fur system allows wet, dirty or matted coats. Animals are trackable and sorted into Rare, Discoverable and Legendary — Rockstar is keeping the rarest ones secret. Per Rob Nelson, they can be “studied” as a collection, a mechanic carried from RDR2 specifically to avoid encouraging players to kill wildlife.
Did you know
- Rockstar says explicitly that the gators are not Grassrivers’ real danger: there are “far deadlier predators and weirder discoveries among the mangroves”. Nobody knows yet what they are.
- GTA 6’s wind system was built to move the swamp grass specifically, as well as rippling water and lifting debris on rooftops.
- The region’s official screenshots do not show a single tourist — they show hunters with rifles on airboats and a police chase through the water.
