The Glow Worm Tunnel Walk is an 11.5km, grade 3 circuit hike, located in Wollemi National Park New South Wales. The hike should take approximately 4hrs mins to complete.

Hike Summary

One of the most popular and famous tracks near Lithgow the Glow Worm Tunnel Walk passes through a spectacular old railway tunnel. With thousands of glow worms along the sides and roof of the tunnel a fascinating effect of the stars is produced. Remember that it is necessary to be quiet so as not to disturb the glow worms. A torch is required - the tunnel is pretty long and it gets really dark in the middle.

This hike is an extended version of the Glow Worm Tunnel Walking Track and completes a circuit via the Old Coach Road.

About the region

World Heritage-listed Wollemi National Park offers a dramatic setting for scenic walks, swimming, canoeing and camping, just a couple of hours north-west of Sydney.

Discover the spectacular landscapes of Wollemi National Park, part of the Greater Blue Mountains World Heritage Area. From scenic canyons, towering cliffs, wild rivers and serene forests, there are ample opportunities to be immersed in the beauty of the largest wilderness area in NSW.

In the southeast of the park, pack a picnic and hike down to the beautiful Colo river for lunch, or riverside camping, in the dramatic surrounds of one of the state's longest and most picturesque gorges.

Set up camp at Newnes, near the Wolgan River, and head out to explore the historic ruins, once the site of an oil shale mining facility, or take the kids to marvel at the luminous occupants of the Glow Worm Tunnel, part of the old railway that once serviced the area. Bushwalkers and rock climbers will thrill at the hikes and climbing opportunities available in this striking, escarpment-bound valley.

In the northwest of the park, Ganguddy (Dunns swamp) offers a tranquil escape. Camp below the remarkable pagoda rock formations and plenty of opportunities for easy walks, swimming and canoeing.
