Around the World in 80 Days filmed at Kogel Bay Beach, Gordon's Bay. The island in Episode 6 was pieced together from two nearby beaches here, using camera trickery. On screen it's Desert island.
Probable Named in published production coverage; the coordinate is the place itself, checked against a gazetteer. This is an area, not a spot. The coordinate is its middle, so use it to navigate to the place and not to line up a shot.
Venture keeps every scene location on one map, sorted by how far you'd have to walk. Open it in Gordon's Bay and it tells you what was shot around you, how to get there, and whether you can actually go in.
