O’Halloran Hill Recreation Park (part of Glenthorne National Park- Ityamaiitpinna Yarta)


O’Halloran Hill Recreation Park is now part of Glenthorne National Park-Ityamaiitpinna Yarta.

This is a newly-proclaimed national park. O’Halloran Hill Recreation Park’s name will gradually transition to Glenthorne National Park-Ityamaiitpinna Yarta.

This southern suburbs park was once cleared and for more than 90 years the area was used for grazing. Today, the shade from the regenerated grey box eucalypts and river red gums provides the perfect spot for a picnic. The bluestone quarry in the park once supplied raw materials for many of Adelaide's older buildings and is still visible today. Stunning views of the city, hills face and coastline can be seen while following the various fire access trails with in the Park

Check out the 18 kms of Mountain Bike trails. The trails use the steeper parts of the park to provide some great downhill options, with trails ranging from easy through to intermediate and advanced.

Getting there

O'Halloran Hill Recreation Park is located 16km south of Adelaide. Access is via Majors Road at Seaview Downs.

Pedestrian access points are situated along Davenport Street, Ridgefield Avenue, Greenfield Road and Fowler Street.

The park is also accessible via the bicycle veloway on either side of the Southern Expressway.

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.

Dogs allowed (on lead)

Dogs are welcome in this park.

Please ensure you:

  • Keep your dog under control and on a lead no more than two metres in length.
  • Stick to designated walking trails.
  • Bring disposable bags to clean up your dog’s faeces (please be aware there are no bins in national parks).

Discover other parks you can walk your dog in on our find a park tool or read 12 dog-friendly walks in Adelaide Parks by Good Living for inspiration.


There are no facilities in the park. Please ensure you carry sufficient water, food and supplies for your entire visit. It is also a good idea to let a responsible person know of your intended movements and when you expect to return.

Useful information

  • Mobile phone coverage is good in most areas of the park.
  • Important: Collection of firewood within National Parks is prohibited. Dead wood plays a vital role in providing shelter for animals and adding nutrients to the soil.

Plants and animals


Nearly the entire vegetation of the park has been cleared in the past and very little natural vegetation remains.

Important stands of Grey Box eucalypts are found throughout the park and include vegetation communities which are poorly represented throughout the Adelaide hills.

Other species include:

  • Golden Wattle
  • Bull Oak
  • Melaleuca species
  • Grevillea and Hakea
  • River red gum.

Various organisations and volunteers have undertaken tree planting, enabling the area to develop into an important and attractive urban bushland resource.


As the revegetation of the park continues and matures, more species of woodland and grassland birds are being recorded. Many species of reptiles thrive in the open grasslands of O'Halloran Hill Recreation Park. There is a small population of western grey kangaroos that call O'Halloran Hill home. There is also the occasional koala passing through the area.

Traditional owners

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

The park is located just south of the Eden fault line. Underlying rock formations are from the Precambrian Umberatana Group.

A bluestone quarry near South Road is still visible and was used for many of the old structures in the city of Adelaide. Both north-west and north-east sections of the park are characterised by deeply divided gullies with steep side slopes.

Nearly 90% of the land was cleared in the early days for grazing and cropping. The ruins located in the south-east corner are the remains of a large Pea Farm built in the late 1800's. The farm later supplied the US Army forces with peas during WW2.

Why does my dog need to be on a lead?

If your dog is off lead, it is more likely to impact on native wildlife and other visitors in a park and be at risk itself.

Risks to wildlife:

  • Dogs off tracks will leave a scent in the bush that will keep wildlife away.
  • Uncontrolled dogs may frighten wildlife and disrupt their natural behaviour.
  • Some dogs will kill or injure wildlife.

Risks to other park visitors

  • Dogs may be aggressive to other park visitors.
  • Even friendly dogs can knock people over causing injury.
  • Some people want to enjoy parks without dogs.

Risks to your dog

  • Poison baits may be laid to control foxes. Baits can be fatal to dogs.
  • Even if your dog is friendly, other dogs may not be.
  • Your dog can catch parasites (such as fleas and ticks) from wildlife.
  • Snake bites are a real risk in natural areas such as parks.
  • Wildlife such as kangaroos and koalas will defend themselves if threatened by a dog and can cause significant injury to or the death of your dog.
