On the way back from Matapouri, we almost stumbled on these falls in a well setup park on the Ngunguru road.
Very nice new toilets too if you’re looking for good loos.

We spent an hour or so wandering around what’s called the inner loop walk which takes you down an easy track to a huge cavern like area with the huge waterfalls falling into a big lake about 100 odd feet below.
There is a picnic table there and a nice area to take it all in.
Well worth a look and good exercise too 😎
