This park is one of Auckland region's 14 Tūpuna Maunga (ancestral mountains).
The area contains One Tree Hill Domain and Cornwall Park, which are next to each other, and often seen as one. There is a playground including a train track for little ones and a skate bowl close to the entrance off Manukau Road.
Both parks are open to the public, however Cornwall Park is a private park and administered by the Cornwall Park Trust Board.
Visit the Stardome Observatory or climb to the summit of the hill to enjoy the incredible view.
Visit the Tūpuna Maunga Authority website for information about any works that may be taking place so you can plan your next visit.
