Port Germein Gorge is the road inland from the coast toward the Southern Flinders Ranges. It is not a formal attraction with gates and ticket booths; it is a scenic drive that explains why the old port mattered, linking wheat country and range country back down to the jetty.
Use it if your route is already turning inland toward Mount Remarkable or the Flinders. The reward is the change from flat Spencer Gulf coast to dry hills and wider views, a quick reminder that Port Germein sits between two very different South Australian landscapes.
