A popular medium day walk is to hike from the Zumsteins car park area (public toilets available) up to Fish Falls and then on up to Mackenzie Falls then return.
This should take around 1.5hrs and you should take the usual hiking gear such as water, sun protection, snakebite bandage (just in case) and mobile phone.
There are possibilities of taking a dip in the water but avoid doing so at Mackenzie Falls as drownings have occurred there.
Zumsteins to Fish Falls part is a bit boring but the falls and the walk from Fish to MacKenzie falls is much nicer and far more interesting – so you may wish to cut this walk in half and park at the much busier Mackenzie Falls car park and walk down to Fish Falls then return.

Walk up the steps to the MacKenzie Falls car park (tends to be very busy especially on weekends and school holidays)
The nearby Smith’s Mill camping ground is in walking distance from the car park. This camp ground requires prior online booking through Parks Victoria – there is minimal if any mobile reception in this region.
