From www.waterfalls.co.nz:

'An easy un-official track leads to the upper waterfalls lookout. It takes just 30 seconds to reach the top of the waterfall, and the track is suitable for people of all abilities.

There is no official track to the waterfall base. It's your own risk if you decide to descend there.'

Note: ideally you combine a trip to this waterfall with the Hunua Falls visit.'
