O'Halloran Hill Circuit Hike (6km)

O'Halloran Hill Recreation Park (Part of Glenthorne National Park-Ityamaiitpinna Yarta)
Located in the southern suburbs of Adelaide, O'Halloran Hill Recreation Park is now part of the newly proclaimed Glenthorne National Park-Ityamaiitpinna Yarta. The park's name will gradually transition to reflect this.

Once cleared for grazing for over 90 years, the park has undergone regeneration. Today, visitors can enjoy picnic areas shaded by native grey box eucalyptus and river red gum trees. A historical reminder can be found in the form of a disused bluestone quarry, which provided materials for Adelaide's older buildings.

Hikers and bushwalkers will find plenty to explore with a network of fire access trails offering scenic views of the city, coastline and hills. For mountain bike enthusiasts, there are 18km of trails catering to a range of skill levels, from beginner to advanced. The park is also dog-friendly, with dogs permitted on leash.

Please note that there are no facilities within the park, so visitors should come prepared with food, water and any other supplies they may need for their visit. It's also advisable to inform someone of your planned route and estimated return time.

While much of the park's original vegetation was cleared historically, regeneration efforts are ongoing. This includes replanting grey box eucalyptus trees, which form an important ecological community in the Adelaide Hills. As the park matures, it's becoming home to a wider variety of birdlife, with woodland and grassland species being increasingly recorded. Additionally, the open grasslands provide habitat for reptiles, and the park is home to a small population of western grey kangaroos. Koalas have also been occasionally spotted in the area.
