History of the Glow Worm Tunnels
Part of the old Newnes railway, the historic tunnel was built in the early 1900s for shale mining. Now the abandoned tunnel is home to glow worm colonies of the species Arachnocampa richardsae. Deep in Wollemi National Park, the tunnels have become an otherworldly environment lit by hundreds of glow worms. Walking through the blackness of the tunnel you’ll be mesmerised by the glow worms on the canyon walls.
How to get to the Glow Worm Tunnels
The Glow Worm Tunnels are accessible via Glow Worm Tunnel Road, off Wolgan Road from Lithgow. From there take Gully Road until you reach the Glow Worm Tunnel trailhead. The road to the tunnels is unsealed so make sure your vehicle can handle it, especially in wet or poor weather. The walking track is 1.5km and goes through forest, including tree ferns and the occasional glow worms.
For a longer adventure you can start at the Wolgan Valley end, walk through Penrose Gorge and Dry Canyon. Hikers can see Horseshoe Falls and the Wolgan River before reaching the tunnel.
What to Expect Inside the Glow Worm Tunnels
Walking in complete darkness you’ll be met with the bioluminescent beauty of thousands of glow worms. They hang from the canyon walls, spinning their silk threads to catch food. The glow worm colonies emit a blue-green light, the tunnel becomes a glowing wonderland. As you walk deeper into the tunnel the tunnel curves and the lighting effect gets more intense, it’s magic.
Glow worms like complete darkness but the natural light at the entrance allows for a gradual transition into darkness. Once inside switch off any artificial light to fully experience the glow worms. Glow worms are sensitive to bright light so try to limit torches and flashlights to avoid disturbing the habitat.
The Best Time to Visit the Glow Worm Tunnels
To see the Blue Mountains Glow Worms at their best, visit during normal weather in the warmer months, October to April. This is when they are most active. The tunnels are open year round but be prepared for different conditions. In dry weather the path is easy but in wet weather the flat path can be slippery.
Visiting during peak times means more tourists, so consider an early morning or late afternoon visit to have a quieter, more exclusive access to the tunnels.
