Port Gellhorn is one of the six regions Rockstar has named in Leonida, alongside Vice City, the Keys, Grassrivers, Ambrosia, and Mount Kalaga.
Rockstar's description, titled 'Live Hard,' calls it 'Leonida's forgotten coast': cheap motels, shut-down attractions, and empty strip malls, with a local economy fueled by malt liquor, painkillers, and truck-stop energy drinks. The same text suggests jumping on a dirt bike and holding on to your wallet.
Back Country Radio is pitched at this part of the state too: Rockstar says the station brings renegade country to the Grassrivers, Port Gellhorn, and beyond. Fan maps put Port Gellhorn in the northwest, on the Gulf side, and compare it with the Florida Panhandle. Without an official map, that position is an estimate.
