This hike, along with others in the Kangaroo Island Wilderness Trail (KIWT) series, is written to support those completing the full multi-day hike. The route descriptions, distances, and logistics assume a staged, continuous journey and are not intended to be used as standalone day walks.
Day four of the Kangaroo Island Wilderness Trail covers 13.5 kilometres between Banksia Campground and Tea Tree Campground. Rated as a grade 4 walk, it takes around five hours to complete and is one of the most exhilarating sections of the trail. The route follows the rugged coastline, where powerful swells crash against cliffs that rise steeply from the ocean. The air is filled with salt spray and the rhythmic sound of the waves, creating an atmosphere that is both wild and deeply stirring.
Leaving the coast, the trail begins to wind inland toward Hanson Bay, and the landscape transforms dramatically. The low, windswept heath gives way to dense mallee and groves of tea trees that provide welcome shade and a sense of calm after the open coastline. As you approach the South West River, the forest opens to reveal one of the trail’s most memorable moments: a scenic punt crossing. This gentle drift across the water marks your entry into the Cape Bouguer Wilderness Protection Area, an untouched part of the island where nature feels raw and undisturbed.
If time and weather allow, take a short detour to Hanson Bay beach. The clear, cool water is perfect for a quick swim, and the setting offers a peaceful break before the final stretch. Returning to the main trail, the path follows the meandering river through Kelly Hill Conservation Park, where the changing light filters through the trees and birdcalls echo in the stillness.
The day concludes at Tea Tree Campground, a tranquil spot beside the historic Grassdale property. A short wander brings you to the restored cottage once home to the Edwards family, among the early settlers in the island’s west. As evening approaches, the surrounding grasslands come alive with movement as Kangaroo Island kangaroos venture out from the bush to graze. Watching them under the fading light is a quiet, grounding end to a day filled with contrasts, from the drama of the cliffs to the gentle rhythms of the inland forest.

4 Reviews on “KIWT - Day 4: Grassdale Section (13.5km)”
Absolutely loved this section of the walk. Started with cliff top walking but soon changed to trails through beautiful bush land.
I fancy myself a bit of a photographer and was slowed down by all the photo opportunities. The area is a haven for orchids, one of my favourite things to hunt and find, so the there were times when the pace got really slow, as I mooched around looking for these tiny flowers.
The punt crossing was easy and a bit of fun and with a seat right next to the punt it was also a good place to stop for lunch. The side trip to Hanson Bay was short and well worth it, although we opted not to walk along the beach, instead just admired the view from the sand dunes.
