From Lithgow head on the Western Highway toward Bathurst. After 10-11Km you will head uphill and see thick pine forest to the right. It's dual carriageway here, and there's a right turn across the other lane into Forest Ridge Drive (signposted and a sealed road). About 50m on the left there's a turning where you can park in the shade. There's also an old concrete section of the highway just past there with masses of parking.
