Locations
Vice City, Leonida and the map beyond it.
Leonida is Rockstar's Florida, and it is unusually easy to read against the real state because the studio has barely disguised the source material. Vice City is Miami, the Keys are the Keys, Grassrivers is the Everglades, Ambrosia is the sugar country south of Lake Okeechobee, and Port Gellhorn is the faded roadside tourism of the panhandle coast.
One region has no real counterpart. Florida's highest natural point is around 345 feet, so Mount Kalaga National Park is an invention, and a lot of writing about it assumes a real place that does not exist.
These pages cover what has been shown, what the real-world equivalent actually is, and what that suggests about how each region will play. Where we are reasoning rather than reporting, the page says so.

Pagasi Residences
Two curved waterfront towers in Vice City, with a third under construction behind them.

Vice City
Rockstar's modern-day Miami, and the centre of the map. Roughly twice the size of Los Santos on its own.

Leonida Keys
Resort islands strung along the coast: tourists, beach bars, water sports, and the smuggling routes underneath all of it.

Grassrivers
The Everglades analogue. Wetland, airboats, alligators, and one of the largest natural regions on the map.

Port Gellhorn
Leonida's forgotten coast. A holiday town that stopped being one, full of cheap motels and shut-down attractions.

Ambrosia
The industrial interior beside Lake Leonida, with a sugar refinery dominating the skyline.

Mount Kalaga National Park
Lakes, rivers and high ground with dangerous wildlife. The closest thing Leonida has to Red Dead's Ambarino.

Stock 305
A graffiti-covered store with a wall of spray cans, named after Miami's area code. Rockstar shot it four times and explained none of it.
