We took the bus out to Cornwall Park, mainly to walk up to One Tree Hill (Maungakiekie), a high point (yes, another old volcano) south of Auckland city center. It's a paved path, so the walk is fairly easy. A large obelisk sits atop the hill - a memorial to Maori.
The walk up is kinda cool because the lower trail traverses land through fields with free range sheep. Melissa was quite happy.
The views from the hill are pretty spectacular.
Cornwall Park was given for public use by Sir John Logan Campbell, who also donated $5000 for the obelisk and is buried on the hill beside it. There is a bit of family resemblance, so who knows...
The park itself is quite nice. We saw a lot of native tree varieties as well as eucalyptus, olive, cherry, horse chestnut, and costal redwood trees. A large fountain dedicated to Sir Campbell is at the opposite end of the park from the One Tree Hill.
