A seat on the Boiler Poiint walkway with a nice view of Careys Bay and the boats. And lots of containers stacked high on the other side of the fence. Sit down and find a 50 ml screwtop container behind you, bring your own pen.
When the container terminal went in, this was one of the two short walkways the port company put in to let people have some access to the harbour, especially for fishing.
The track only goes a little bit further, past some old crane weights which look like Easter Island statues looking out to sea http://www.ost-sculpture.org.nz/press/the-sentinels/ and two old anchors.
