UPDATE 2019: The Ollera Creek Track was recut by Michael Mohring, his friends, and some other members of the public (including members of the Wanderstories community). Now the trail is well-marked up to Mickle's Entry (see interactive map below). Note that the start of this track has not been recut, however, as most people access via private property after gaining permission from the property owners.
Ollera Creek has so much to offer, especially great waterfalls, but also many rock slides and gorgeous swimming holes. Arguably, the most beautiful waterfall in this area is Big Ollera Falls. The area also hosts a stunning creek with a six square kilometre catchment above Ollera Falls, which means that you will experience good flow in the creek year-round.
It is best accessed via private property so prior permission is required if taking this route.
