You won’t find this waterfall marked on any map… nor am I sure what it’s really called… but Stephanie who runs Epiphany Tours calls this the Marble Falls, which seems appropriate.
The Macquarie Rivulet flows under and around a number of enormous boulders, which resemble over-sized marbles. The waterfall is just above the Mulangong Falls.
Getting to Marble Falls
Marble Falls is reached via the Clover Hill Trail (off the Illawarra Highway), which is mostly easy walking along a disused forestry trail as far as Rainbow Falls. The route then follows the Macquarie Rivulet upstream past three more waterfalls, but there is no marked track and some scrambling and route-finding is required.
