All in Map & worldWhere is Port Gellhorn on the GTA 6 map?
Port Gellhorn is presumably on Leonida’s northwest Gulf coast.
The region is official. The west, on the Gulf Coast, is an inference: in Florida, part of the Gulf of Mexico coastline is called the “Forgotten Coast,” and fans place the city there based on trailer footage as well.
