Day 1: Flinders Chase National Park
Flinders Chase National Park on the western end of Kangaroo Island deserves its own day of exploration. Start the day at the Visitors Centre and pick up some information about walks in the park before beginning on the Platypus Waterholes Walk. Afterwards, jump in the car and head south to Admirals Arch, where you can admire the New Zealand fur seals that hang out beneath the stone structure. Check out the Remarkable Rocks, then hightail it up to the Cape Borda Lightstation for an afternoon tour.
Day 2: Wildlife Galore
At the Hanson Bay Wildlife Sanctuary, you can head out on a self-guided walk to spot koalas before eating up a leisurely lunch at the visitors center. Then, head five minutes up the road to take an adventure tour at the Kelly Hill Caves and explore the area's many short hiking trails. End the day at the Seal Bay Conservation Park for a spectacular sunset tour.
Day 3: History in Kingscote
Stick closer to Kangaroo Island's main town and be rewarded with the rich history found just north of Kingscote at Reeves Point. The initial location for South Australia's capital city, Reeves Point is home to an old cemetery and the Hope Museum. End the day with a relaxed tour to view the city's little penguin population after dusk.
