O'Halloran Hill Recreation Park is located 16km south of Adelaide. Access is via Majors Road at Seaview Downs. The O'Halloran Hill Recreation Park can be explored via its network of walking trails, horse riding trails and fire tracks.
You can also cycle your way through the park on the bicycle veloway, a seven kilometre sealed bike track running alongside the South Expressway.
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.
