At the beginning to the track it doesn't look all the promising for people looking for waterfalls. It is Sclerophyll forest.
Sclerophyll forests are a typically Australian vegetation type having plants (typically eucalypts, wattles and banksias) with hard, short and often spiky leaves, which is a condition closely associated with low soil fertility (rather than rainfall/soil moisture). www.environment.nsw.gov.au
It's a circuit but I quickly decide that Adelina Falls the little dot close to the bottom will be enough for me today. The sign says it is only 300 metres but its all down down down from here and up up up again afterwards.
