Muluerindie is a Cabin managed by NPWS right next to the river which requires a booking and access is via private property with locked gates.
Nearby there is a scattering of good bouldering which is a great way to while away some time between margaritas on the deck overlooking the gorge.
There seems to be more potential upstream. Also note that the other side of the river is private property.
You can see the river levels here, levels above 1.5m may not be good.
