A must do when in Queenstown, Deer Park Heights is a privately owned land that you pay $75 per car to drive all the way up to the top and you can buy animal feed for $2 (make sure to bring coins), there is pigs, goats, cows and deer (although be careful with the deer as you aren't allowed near the ones with antlers). 

For all our LOTR fans, there is also sections here where it has been filmed along with X-Men and so on.
