[1] Accessible by the Wolgan Valley Discovery Trail (Wolgan Road) from the Castlereagh Highway, the road travels through the valley leading onto the historical village of Newnes and its extensive industrial ruins.

Four heavy Shay type locomotives were used to haul the products of the works at Newnes up grades as steep as 1 in 25.

The name of the Wolgan Valley is derived from "wolga", a local Australian Aboriginal language name for the climbing plant, Clematis aristata, found in coastal regions of the South-East states of Australia.

The bush walking trails in the area include the Pipeline Track, which goes from Newnes to Glen Davis,[2] and the Wolgan Valley Heritage Trail (see links below), as well as the track from Newnes to the Glowworm Tunnel.

This project was opened by Emirates Groups Hotels and Resorts after examining several sites in Australia.
