Hear how to pronounce this park name

Glenthorne National Park-Ityamaiitpinna Yarta is a new national park in Adelaide’s southern suburbs. The park is located 16 km south of Adelaide on Majors Road in O’Halloran Hill.

The park is now open and you can walk a 4km temporary loop trail (see map). The trail starts and ends at the park’s ranger station just off Majors Road.

The former 208-hectare Glenthorne property is being revitalised through an extensive revegetation program – an area the size of almost 80 Adelaide Ovals. Once construction is complete, visitors can expect to enjoy a nature play space and picnic area, wetland, camping facilities, walking trails and heritage precinct.

O’Halloran Hill Recreation Park is located next to the Glenthorne property and has been renamed as part of Glenthorne National Park-Ityamaiitpinna Yarta.

This area will join a large precinct of existing parks and open spaces in Adelaide’s south that will span almost 1500 hectares, which is almost twice the size of Belair National Park and includes Hallett Cove Conservation ParkMarino Conservation Park and Happy Valley Reservoir, which will open to visitors by the end of 2021.

Please ensure you:

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, or you can live chat with a customer service representative on the website Monday to Friday from 9am to 5pm.

More than 90 bird species have been recorded at Glenthorne. Stay a while and you might be lucky enough to spot small flocks of yellow-tailed black cockatoos and the more elusive grey fantail.  

Keep an eye out for these commonly sighted birds:   

  • Adelaide Rosella - Platycercusadelaidae
  • Grey fantail - Rhipidura albiscapa

Traditional owners

The Kaurna People are the Traditional Owners of the lands and waters of the greater Adelaide region, including Glenthorne National Park-Ityamaiitpinna Yarta. They maintain a deep relationship with Country, and have done so for tens of thousands of years through their customs and Tjukurpa. 

Tjukurpa, which includes cultural stories and lore, is vital to understanding the cultural significance of Southern Adelaide, and will profoundly influence the way the Glenthorne National Park-Ityamaiitpinna Yarta is managed.


European history

Glenthorne National Park-Ityamaiitpinna Yarta will include a number of historically important areas that will be preserved as part of the park. 

The former Glenthorne property has a rich history, settled in 1839 by the state’s first police commissioner Major Thomas Shuldham O’Halloran. It has been used as a farm, a training ground for military horses in WWI, a research facility from 1949, and is now set to become a heritage precinct within the park. 

Each of these phases of history are reflected in the historical building remains on the site, dating back to the 1950s. 

The old Worthing Mine buildings in the Lower Field River Valley also provide an example of how copper mining took place in South Australia in the 1800s. 

See and do

Glenthorne National Park-Ityamaiitpinna Yarta has opened its gates to the public. You can now take a walk along the park’s 4km temporary loop trail, which starts and ends at the park’s ranger station just off Majors Road, at O’Halloran Hill. The trail features interpretive signage that gives insight into the park’s rich history and future plans.


A dedicated volunteer program has been established for the Glenthorne National Park-Ityamaiitpinna Yarta precinct. Find out more about the Glenthorne Action Team here.
