This is one for the 4WD only I'm afraid which is why it rates so high for terrain.
Landcruiser Mountain Park is a private 4WD park covering over 8000 acres. You pay your money and the place is yours - go crazy on 200 kms of graded 4WD tracks for as long as your vehicle and passengers can take it. Pay a couple extra bucks per day and you can camp there too - you can even take the dogs.
The first thing to do is visit the office (which is located at S26 34.520 E152 19.300) to pay your money. How you get to the cache is up to you but you shouldn't have to go on anything other than the green (easy) tracks to get there.
