Kangaroo Island is Australia's third-largest island — about 150 km end to end — and its headline sights are spread far apart. Fuel is sparse outside the main towns, so fill up before pushing west. Wildlife is most active at dawn and dusk, which makes night driving slow and risky. And the SeaLink ferry timetable, not your map ETA, is the real anchor of any KI itinerary. Plan around distances, not optimistic Google Maps times.
Approximate planning figures — drive to conditions, avoid dawn/dusk wildlife strikes, and the ferry is your real schedule anchor.
Figures below are point-to-point road estimates (treat ±10% as normal). Some final-access precinct roads may be unsealed — always confirm current conditions locally before heading out.

Driving distances from Penneshaw
