About the Walking Trail
Spend 5 days hiking the The Kangaroo Island Wilderness Trail along the spectacular coastline of south-west Kangaroo Island. Follow the Rocky River, walk along the wild west coast, take a side trip to Admirals Arch and the Remarkable Rocks, walk to Hanson Bay and return inland through the forests to Kelly Hill.
The trail opened in 2016, and is a 5-day trail with campsites along the way, although there are day walk options available through some tour operators. The first day in the Rocky River Section, and the 5th day in the Kelly Hill Section can be hiked by anyone, but the middle 3 days are only accessible to people who have paid the $161 trail trail fee.
The trail distance is 60.4km on the main trail, with 12.6km of return side trips (73km overall).
Each campsite has tent sites for self-guided walkers, and a separate area for group tour tent sites, a communal kitchen and dining shelter, toilets and rainwater.

Reaching the Pardalote Lookout you will see the meandering Rocky River far below you as it flows out towards the Southern Ocean. You will then pass through riverbank and mallee habitats where wildflowers provide stunning arrays of colour all year around, along with orchids and fungi in the cooler months. Traversing your way down from the ridge towards the river you will come across the spectacular sight of the Rocky River Cascades.

Pause for a final look back on your day’s journey along the spectacularly beautiful coastline of Maupertuis Bay. When the trail turns inland you’ll be treated to softer conditions underfoot for the final stretch to camp. Tucked away in a swale, the Hakea Campground offers you protection from the relentless coastal winds and will lull you to sleep with the relaxing soundtrack of crashing waves on the nearby cliffs.
