After breakfast, drive to the Kangaroo Island Wilderness Trail trailhead. Before walking, spend time at the national park visitor center, where you can learn more about the island's history, wildlife and wilderness areas. The day's main trail section leads toward Snake Lagoon, moving through forest, coastal vegetation and rougher island country. Keep watch for kangaroos, echidnas and unusual plant life as the trail shifts underfoot. Later, settle into your Karatta cabin, your base for the next three nights.
