The Cape Gantheaume headland experiences seasonal closures to protect nesting white-bellied sea eagles, a vulnerable species. These closures typically occur from May until the end of December each year. To confirm the current status and for any updates, visitors are advised to consult the official website of the National Park managing Cape Gantheaume.
The Cape Gantheaume Coastal Hike is a challenging 33-kilometer, two-day trek through Cape Gantheaume Conservation Park on Kangaroo Island, South Australia. It is classified as grade 5, signifying a difficult hike. The journey begins at Bales Beach and traverses a series of secluded sandy beaches for the first 6 kilometers eastward. The path then transitions to cliffside walking as it progresses towards Cape Gantheaume. A beach can be found on the western side of the headland, while the western coastline itself is dominated by cliffs with a beach near the conclusion. The hike terminates at the carpark situated at Sewer Beach, a rocky shore in D'Estrees Bay.
Meticulous planning is crucial for undertaking this trek due to the following challenges:
- It is a one-way journey spanning two days.
- Camping at Cape Gantheaume headland is highly recommended, but there are no designated campsites.
- No water source exists along the trail; hikers must carry a sufficient supply for the entire duration. A rainwater tank can be found at the Bales Bay carpark (with Seal Bay a further 4 kilometers west). The closest source of water in D'Estrees Bay is Wreckers Beach, located 2.5 kilometers west of the Sewer Beach trailhead.
- The majority of the route lacks a defined trail; a rough fire track exists between D'Estress Bay and the Cape Gantheaume headland.
- Consulting with park rangers beforehand is mandatory. They can provide the Trekking Information Sheet and discuss your plans in detail.
The Cape Gantheaume headland experiences seasonal closures, typically from May to December, to safeguard nesting white-bellied sea eagles, a vulnerable species. These majestic birds are susceptible to disruption during breeding periods as they have exceptional eyesight, allowing them to detect approaching humans from vast distances. To ensure the well-being of the eagles and their young, they return to the same nesting sites year after year. Park authorities recommend checking the National Park website for the latest information on these closures.

Getting to the trailhead: Cape Gantheaume Conservation Park.
Reaching Cape Gantheaume Conservation Park requires a journey to Kangaroo Island. From mainland South Australia, travelers can board the SeaLink vehicle and passenger ferry which operates daily (excluding Christmas Day) between Cape Jervis (a two-hour drive south of Adelaide) and Penneshaw on Kangaroo Island. The ferry ride takes approximately 45 minutes to cover the 16-kilometer distance. Once on Kangaroo Island, the park itself is located 40 kilometers southwest of Kingscote. Access varies depending on your desired destination within the park. Murray Lagoon can be reached via Birchmore Road, while the coastal section, including D’Estrees Bay, is accessible through Elsegood Road or D’Estrees Bay Road. The trailhead for this hike can be accessed via Bales Bay Road.

Encompassing vast wilderness areas, Kangaroo Island's largest lagoon, and stunning coastal scenery, Cape Gantheaume Conservation Park and adjoining Wilderness Protection Area form a spectacular natural reserve on the island's south coast. This expansive area of pristine coastline is a vital contributor to biodiversity. It provides a continuous block of vegetation that connects to Seal Bay Conservation Park, creating a critical corridor and habitat for a range of rare and threatened species.
The park offers diverse walking opportunities. Experienced hikers can tackle the unmarked Cape Gantheaume Coastal Trek. Established trails wind around Murray Lagoon, an important wetland habitat for abundant birdlife (though be aware of potential winter flooding). D'Estrees Bay boasts beautiful beaches perfect for relaxation, and holds historical significance linked to the island's early whaling industry. Large deposits of seagrass washed ashore along these beaches are a testament to the extensive seagrass meadows flourishing beneath the bay's shallow, sunlit waters, made possible by the low wave energy. It's important to note that dogs are not permitted within the park.
The bay itself was named in 1803 by French explorer Nicolas Baudin in honor of Jacques D'Estrees (1660-1737), a French author, military leader, and government official.

AWTGS. These are only recommended for very experienced and fit walkers with specialised skills, including navigation and emergency first aid. Tracks are likely to be very rough, very steep, and unmarked. Walks may be more than 20 kilometers. These challenging walks demand a high level of fitness and experience to navigate difficult terrain, significant elevation changes, and potentially unformed paths.
