Leonida is a full state, not just a city. Confirmed regions from trailers and official material include Vice City (Miami), the Leonida Keys (Florida Keys), Grassrivers (the Everglades), Port Gellhorn (Gulf-coast panhandle), and Ambrosia. Expect swampland, beaches, small towns, and highways connecting them.
Rockstar has never released square-mileage figures before launch, so every size claim you see is an estimate. Community mapping projects, which reconstruct the map by cross-referencing trailer frames and screenshots, converge on roughly 1.5–2× GTA V’s landmass with substantially more enterable interiors. Treat exact numbers as provisional until the game ships.
Our interactive map plots every confirmed point of interest, landmark, and enterable building from official material onto the community-reconstructed map — and it updates as new locations are confirmed. When the official in-game map releases, we will swap it in.
