Marne Valley Conservation Park


The 105 hectare Marne Valley Conservation Park is bisected by the Marne River, which provides a focal point for the park.

The park was dedicated in 1976 and consists of gently undulated land. Much of the park is comprised of low lying, seasonally inundated giant river red gum flats. Other vegetation communities in the park include mallee boc, narrow-leaf mallee and white mallee. In the south western corner, along the eastern central boundary, and along the northern boundary the native vegetation has largely been cleared. The cleared areas are low open shrublands dominated by various exotic grasses, ephemerals, small-leafed bluebush, climbing twinleaf, bassia, balcarra grass and bladder saltbush.

Visitors can access the park by foot by several of the management tracks, but should be mindful of seasonal conditions prior to setting out. Walk quietly and you may be rewarded with sightings of western grey kangaroos taking shelter in patches of vegetation or feeding on the grasslands. If you have a keen eye you may also spot waterfowl or hear the distinct call of the iconic kookaburra echoing through the red gum woodland.

Assistance dogs

Assistance dogs are permitted in most public places and are therefore welcome in South Australia’s parks and reserves. Assistance dogs must be appropriately restrained on a lead and remain under your effective control at all times while in a park or reserve.

As per the dogs in parks and reserves policy, if the dog is not an accredited assistance dog, they must be trained to assist a person with a disability to alleviate that disability and meet standards of hygiene and behaviour appropriate for a dog in a public place. However, refusal may be given if the person with the disability is unable to produce evidence the dog is an assistance dog with the appropriate training.

Before taking your assistance dog into a park that does not normally allow dogs, it is highly recommended that you contact us so we can provide you with the latest information on any potential hazards within specific parks that may affect your dog. Please contact the park via the contact details provided under the contact tab or contact the visitor service centre via email or on Facebook.

Traditional owners

Prior to being called the South Rhine River and then the Marne, the river was originally known by the local Ngarrindjeri Aboriginal People as Taingappa, meaning ‘foot track-trading road’. The Ngarrindjeri People once used the river as a route up into the hills to trade with the Peramangk Aboriginal People in the Barossa Valley, and to cut bark canoes from the river red gums in the hills, which had thicker bark than those near the Murray River.

Aboriginal peoples have occupied, enjoyed and managed the lands and waters of this State for thousands of generations. For Aboriginal first nations, 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.

There are many places across the State that have great spiritual significance to Aboriginal first nations. At some of these places Aboriginal cultural protocols, such as restricted access, are promoted and visitors are asked to respect the wishes of Traditional Owners.

In places where protocols are not promoted visitors are asked to show respect by not touching or removing anything, and make sure you take all your rubbish with you when you leave.

Aboriginal peoples continue to play an active role in caring for their Country, including in parks across South Australia.

European history

Long before the park was dedicated in 1976, the area was once part of the main Adelaide to Sydney stock route.
