This walk begins at Mulligans Hut, where an interpretive sign and map describes William Mulligans plan for a hydro electric scheme to power his copper mine. Mulligan envisaged two storages dams, on Dandahra and Little Dandahra Creeks, tunnels and pipelines, taking advangage of the 600 metre drop. He built two weirs to test water flow. Funding was not forthcoming, and the grand vision was never built.
This walk leads to Murrumbooee Cascades, where remains of Mulligan’s weir can still be seen. Except if it has been raining, and the river is flooding, as in our case!
Soon after leaving the picnic grounds, a short detour goes to Barra Nula Cascades on Little Dandahra Creek. Beyond that, the track leaves the drier eucalypt forest and enters rainforest, with many walking stick palms, bridges over streams, and chirpy birdlife. It is a pleasant, easy walk as you go steadily downhill to the creek. After rain, expect some mud, and a steady up hill climb on the way back!
