About this walk

The tunnel was cut in 1907 for the Wolgan Valley Railway, which hauled shale oil out of Newnes. The rails are long gone and glow worms have moved in. Walk to the middle, turn off your torch, stay quiet and let your eyes adjust.

The track to the tunnel passes pagoda rock formations and tree ferns and was rebuilt with a new carpark and boardwalk, which is why the walk is longer than older guides say.
