Rialto Islands

The first trailer shows the Rialto Islands from above. The shot looks down on three islands set in a southern Leonida bay, with the Vice Beach skyline visible behind them.

A road links the islands. What appears to be a toll booth stands on the westernmost island, while yachts and other boats fill the surrounding water.

Grand Theft Auto VI: An Extended Look later names the Rialto Islands on an overhead road sign as Jason and Lucia drive through Vice City.
