Cornwall Park is a landscaped park designed for the recreation and enjoyment of all the people of New Zealand.
The park is renowned for its landscape design and its wide variety of mature trees. It is centred on a volcanic cone, One Tree Hill, with many interesting geological features.
A pre-European Maori fortification (pa) was built on the cone, many features of which can still be seen.
The park's donor, Sir John Logan Campbell, is buried on the summit of One Tree Hill alongside the obelisk. The Maori name for the hill is Maungakiekie - mountain of the kiekie.
Kiekie (Freycinettia banksii) grows as an epiphytic climber or vine. Immediately adjacent to the Park is One Tree Hill Domain, administered by Auckland City Council.
The two parks are run under different management but with very similar objectives. Visitors can experience them as one park.
