  • Glow Worm Tunnel is home to thousands of glow worms. Help protect them by staying on the path.
  • Please take care in the tunnel as it’s completely dark and the ground can be slippery. 
  • When you turn off your torch, take the time for your eyes to adjust to the darkness before you see the glow worms.
  • Try to keep noise to a minimum as glow worms are sensitive to sound.
  • Shine your torch on the ground or use one with a red-light option as red-light is the least disruptive for glow worms.

Glow Worm Tunnel via Wolgan Valley loop is a walk you'll want to write home about after spending 4-5 hours in Wollemi National Park's world-heritage scenery.

The diverse and dramatic features on this walk include a historic railway tunnel with glow worms, the lush rainforest in Penrose Gorge, alien rock formations known as pagodas, and spectacular cliffs offering views out over Wolgan Valley.

Start from the Glow Worm Tunnel carpark and walk 1.5km to reach the loop. Turn right at the fork to walk the circuit anti-clockwise to minimise uphill sections. This also leaves the tunnel to the end of the walk and will allow you to spend as much time as you like seeing the glow worms. The first half of the loop along Pagoda track takes you through forests of twisted angophoras, waratahs, golden wattle, and banksias. You may even spot lyrebirds, goannas, gang-gang cockatoos and brush-tailed rock wallabies. You'll also see ‘platy’ pagoda rock formations. These are unique to the area because of their rough, sometimes striped surface, while most pagodas are smooth.

After about 3.2km, you'll reach a 4-way intersection. Take the first left to stay on the loop heading towards Glow Worm Tunnel following the old railway passage with heritage stone wall and railway sleeper remnants. After about 8km of peeking through trees the full view of the valley opens up at a lookout over Donkey Mountain, Wolgan Valley and Penrose Gorge.

Continue along Tunnel Creek surrounded by rainforest and narrow gorges before you reach Glow Worm Tunnel. Built in the early 1900s as part of the old Wolgan Valley railway track connecting Lithgow to Newnes, the tunnel is home to thousands of glow worms that cling to the dark, damp walls. At 387m long, it's dark enough for you to see glow worms during the day. Upgrades to the walking track to even out the surface and install a handrail make navigating in the dark easier. Switch off your torch, stay quiet, and wait for the tunnel to gently light up.

Glow Worm Tunnel via Wolgan Valley loop is in Wollemi National Park. Here are just some of the reasons why this park is special:

    Ancient connections

    The area that is now Wollemi National Park has held significance to Aboriginal people for at least 12,000 years. Evidence of this connection can be seen throughout the park, including ceremonial grounds, stone arrangements, grinding grooves, scarred trees and rock engravings. There are around 120 known Aboriginal sites in the park and probably many more yet to be discovered. The Wiradjuri, Dharug, Wanaruah and Darkinjung people have a strong and ongoing cultural association with their traditional lands and waters.

    Geological marvels

    Wollemi's landscape has been sculpted over millennia into a magnificent network of soaring sandstone escarpments, plunging gorges and canyons, winding river valleys and awe-inspiring geological and geomorphological features such as pagoda rock formations, basalt-capped mountains and diatremes. The spectacular Colo gorge and its tributaries form the most extensive sandstone canyon system in eastern Australia. Grab your camera and discover for yourself the breathtaking vistas and natural marvels that make this a World Heritage treasure.

    Nature's haven

    It's little surprise that Wollemi's spectacular landscape shelters a rich diversity of plants and animals. The rare Wollemi pine - a 'living fossil' whose closest relatives thrived some 90 million years ago was rediscovered here in 1994, and the park protects an incredible array of botanical species and communities, from open eucalypt forest and woodlands including Hawkesbury and grey box, to rainforests and perched swamps. This variety makes it an appealing habitat for eastern grey kangaroos, red-necked wallabies and the elusive brush-tailed rock wallaby, as well as the beautifully marked broad-headed snake, regent honeyeater and glossy black cockatoo. Around 55 species of butterfly have also been recorded.
