We recently visited Dunedin with our extended family. Mima's Dad grew up there but Mima and I had never been. While we were slightly restricted by naps we really enjoyed our short visit. One highlight was a park Mima's Dad used to go to as a child, Marlow Park Playground in St Clair Dunedin.
It is a true retro gem! While they have adding new generic playgrounds the old playground still stands. Including snake swing, boot and dinosaur slides and a whale which in summer used to spurt water (not sure if it still does), all brilliant.
