The Glow Worm Tunnel trail is one of the most iconic walking tracks in the greater Lithgow region with its draw card – the spectacular display of illuminating glow worms in the historical Wolgan Valley Railway Tunnel No.2, and unmissable panoramic views across Wolgan Valley and the Greater Blue Mountains World Heritage Area.
Described as being one of the most expensive privately funded engineering feats of its time, the Wolgan Valley Railway was the brainchild of chief railway engineer Sir Henry Deane in 1906 and served the nearby Newnes Shale Oil Refinery for the first few decades of the 20th century. The shay engines and rail lines; as well as the dedicated people that worked the railway, have long since gone and nature has now reclaimed much of this once revered and celebrated railway line.
Following the historical footprint of the Wolgan Valley Railway, the hike traverses often steeply graded and densely forested slopes onto spectacular panoramic views of the Wolgan Valley. The nine kilometre trail meanders through fern tree laden gorges, sandstone pagodas and canyons and mountain streams to the aptly named Glow Worm Tunnel.
