Cape Gantheume Conservation Park includes vast areas of wilderness and spectacular coastal scenery. Take a self-guided drive along D'Estrees Bay, marvel at the abundant wetland birdlife and stay in a campsite by the beach.


Vast areas of wilderness, the Island's largest lagoon and coastal scenery provide a spectacular backdrop to Cape Gantheaume Conservation Park and adjoining Wilderness Protection Area on the south coast of Kangaroo Island. This large area of pristine coastal environment is important for biodiversity and provides a continuous block of vegetation adjoining Seal Bay Conservation Park, a critical corridor and habitat for a range of rare and threatened species.

The park has plenty of walking opportunities, including the unmarked Cape Gantheaume Coastal Trek (experienced hikers only), established trails at Murray Lagoon (may be subject to flooding in the winter months), and short walks at D’Estrees Bay.

Murray Lagoon supports wetland habitat for abundant birdlife, while D'Estrees Bay has beautiful beaches for recreation. This bay is a historic site connected to the island's early whaling industry.

The self-guided drive along D'Estrees Bay Road allows the visitor to discover the natural and cultural significance of the area. Designated points of interest along the 8km drive are marked with a silhouette of an osprey bird.

Access to Southern Kangaroo Island Marine Park is also available from this park.

Opening hours

Open 24 hours a day, seven days a week.

This park is closed on days of Catastrophic Fire Danger and may be closed on days of Extreme Fire Danger.

Listen to the local area radio station for the latest updates and information on fire safety.

Useful information

Traditional owners

Aboriginal South Australians are the first peoples of our State and have occupied, enjoyed and managed these lands and waters since the creation. For SA's First Peoples, creation ancestors laid down the laws of the Country and bestowed a range of customary rights and obligations to the many Aboriginal Nations across our state. 

Aboriginal peoples' oral histories and creation stories traverse the length and breadth of Australia’s lands and waters, including South Australian Parks. These stories interconnect land and waters with complex meaning and values and hold great cultural significance. We recognise and respect Aboriginal people's ownership of their stories and that they hold rights and obligations to care for Country. It is through these rights and cultural obligations and a shared goal to protect the environment for generations to come that DEWNR is committed to meaningful collaboration and involvement with Aboriginal peoples in the management of our shared parks.


In 1803 the French explorer Nicolas Baudin circumnavigated Kangaroo Island. He named this long, sweeping bay after Jacques D’Estrees (1660–1737), a French author, Marshall of France, Vice-Admiral and Minister of State.

Further detailed information about the history of Cape Gantheaume Conservation park can be found in the Cape Gantheaume Conservation Park D'Estrees Bay Self-guided Drive brochure.

See and do


Bushwalking is a fantastic way to connect with nature, keep fit and spend time with family and friends. 

South Australia's national parks feature a range of trails that let you experience a diversity of landscapes. Our trails cater for all levels of fitness and adventure and our classification system makes it easy to select an experience suitable for you.


  • Cape Gantheaume Coastal Trek

    This trek is suitable for experienced walkers only. If you're planning an overnight walk or longer, you must discuss your plans with a ranger.

    The trek begins at the Sewer car park at D’Estrees Bay. From this point follow the old vehicle track to Cape Gantheaume where you will find an isolated pristine beach dotted with New Zealand fur-seals. (Warning: Cape Gantheaume beach has strong rips and is unsafe for swimming).

    From Cape Gantheaume, the trek is unmarked and trekkers need to find their own path through the coastal vegetation until they reach the Bales Bay car park.

Mountain biking

Mountain biking is currently not permitted in this park. 


Along the beaches of D’Estrees Bay you will see large deposits of seagrass washed ashore. Extensive seagrass meadows flourish in D'Estrees Bay due to the low wave energy and shallow, sunlit waters of the bay.

Seagrass meadows play a vital role in the food chain of near shore marine ecosystems, providing a home for many animals including fish, crabs, sponges, sea snails and octopus. Many fish also use the meadows as areas in which to breed.

Australia's temperate waters contain some of the largest and most diverse seagrass beds in the world. Often described as the lungs of the ocean, these meadows are vulnerable. Many thousands of hectares of seagrasses have died over the last century, smothered by the increased loads of sediments and nutrients entering our oceans, which reduce the intensity of light reaching the grasses. Once damaged, the dominant temperate seagrass posidonia may take hundreds of years to regrow and recolonise.

More information about specific plants which can be spotted in this park can be found at the end of the Cape Gantheaume Conservation Park D'Estrees Bay self-guided drive brochure.


Between May and October you could be ‘in the right place at the right time’ and glimpse the tail of a southern right whale rising from the ocean’s surface, before splashing to the depths below. These whales migrate from the Antarctic to the warmer southern Australian coastal waters to give birth and mate. During this season they fast, and feed again on krill, when they return south.

Keep a watch for osprey plunging feet first into the sea to catch fish. Ospreys are coastal raptors that hunt close to the shore – along cliff lines, in sheltered bays and river estuaries. Each year two to four eggs are laid in September - October in a bulky nest constructed of sticks, on the cliff-top close to here.

The osprey is listed as a ‘vulnerable’ species. In spring and summer both eggs and chicks are at threat from inquisitive people. Eggs can die in the cold air if the incubating parent is forced to leave the nest. Once hatched, chicks are less likely to be fed if the parents or nest are disturbed.

There are many other birds which frequent this area, keep an eye out for the rock parrot, ruddy turnstone, sooty oystercatcher, australasian gannet, hooded plover and the crested tern.

Kangaroo Island's rugged coastline offers keen bushwalkers spectacular coastal scenery, pristine rivers, tracts of undisturbed native vegetation and opportunities to observe abundant and diverse wildlife. Most of the coast is very isolated and provides trekkers with a true wilderness experience. However, this isolation also means that good planning is essential to ensure that your trek is as enjoyable and safe as possible. Some parks are closed seasonally to protect threatened species during their breeding season. We recommend discussing any trekking plans with a Park Ranger. 

Essential trip preparation includes:

  • Sufficient water for the conditions
  • Protective clothing and footwear suitable for the activity and the season
  • Sunscreen and a wide brimmed hat
  • Food for the duration of the trip PLUS emergency rations and snacks
  • Nominating an emergency contact person
  • First-aid kit
  • Map, compass, torch, mirror

Be sure to familiarise yourself with any fire restrictions or park closures.

Remember to establish a point of contact. Tell someone where you are going and when you expect to return. In the case of longer walks, write down your route and leave it with a responsible contact person. 

Provide as much information as possible to your designated responsible contact person. This includes:

  • List of participants
  • Dates
  • Daily trip log (start & finish points)
  • Planned route
  • Vehicle make, model, colour, registration
  • Knowledge of any pre-existing medical conditions of the participants
  • Communication / safety plan. Nominate how best they can contact you (mobile/satellite phone, radio, GPS, EPERB) and who they contact in case of your not returning.

Your responsible contact person can raise the alarm if you have not returned and/or contacted them by the time specified by you.


When camping in a National Park, it's important to remember the following:

  • Always let someone responsible know your travel plans, especially when travelling in remote areas. It's a good idea to let them know when you expect to return.
  • Check the weather forecast before you leave, including overnight temperatures on the Bureau of Meteorology. Even during very mild weather, the nights can get very cold. 
  • The quality and quantity of water cannot be guaranteed within parks. Please bring plenty of water and food to be self-sufficient.
  • Always camp in designated sites (where applicable) - do not camp beneath trees with overhanging branches, as they can drop without warning. It's also a good idea to check that there no insect nests nearby.
  • Check to make sure you're not camping in a natural waterway, flash floods can happen anytime.
  • If camp fires are permitted, you must bring your own firewood, as the collection of firewood within National Parks is prohibited. Extinguish your camp fire with water (not sand or dirt) until the hissing sound stops.
  • Ensure that you are familiar with the fire restrictions for this park.


This park is closed on days of Catastrophic Fire Danger and may be closed on days of Extreme Fire Danger.

Listen to the local area radio station for the latest updates and information on fire safety. 

Fire restrictions
