Glenthorne National Park-Ityamaiitpinna Yarta

Glenthorne National Park-Ityamaiitpinna Yarta is a 1,500-hectare national park at O'Halloran Hill, about 16 km south of Adelaide, South Australia. Proclaimed in 2020, it is metropolitan Adelaide's newest national park, created from the historic Glenthorne Farm and adjoining O'Halloran Hill Recreation Park and other lands. The park conserves open grassy woodlands, wetlands and revegetation areas, with walking and cycling trails, picnic areas and views toward the city and coast.

Visitors can expect a large open-space park on gently undulating land with grassy woodlands, open paddocks, wetlands and newly revegetated areas. The park has a network of walking and shared-use cycling trails, including sealed and natural surfaces, picnic areas with shelters, lookouts with views over Adelaide and Gulf St Vincent, and interpretive signage about natural and cultural heritage. The environment is semi-natural and recovering, with birdlife, kangaroos and seasonal wildflowers.
