A 4.5 hour 4WD tour, stopping at Coulthards Lookout and Sillers Lookout - both with extensive views of the area.
The road itself follows an old mining track.
Knowledgeable guide provided information on the history, geology, flora and fauna of the area, as well as details of what happened in the past and the different rocks, plants and animals . . .
Not cheap, but definitely worthwhile.
