So Hamilton, New Zealand is what I class as an Ok place and therefore in my opinion worth a miss.
Let me explain. If you want city life then Auckland isn’t that far, or even better take the time to go to Wellington which I loved. If you want adventure then you are close to Taupo, or even the amazing Mt Taranki near New Plymouth. If you want scenery then go to nearby Rotorua to see the Guisers and the stunning Redwood. Don’t get me wrong Hamilton has city, adventure and scenery, its just inferior to nearby places.
Of course if you have made your mind up to go to Hamilton, then there are three must dos. 1. Duck Island ice cream-its so good I’m getting hungry thinking about it. 2 The beautiful Hamilton Gardens. 3. The museum, which is free, has a really interesting WW1 section.
