This is a wonderful adventure walk that was upgraded by NPWS in 2024. The whole family will enjoy. The Glow Worm Tunnel is one of two now abandoned tunnels on this railway. This tunnel curves through almost 180 degrees and consequently, it is very dark. In normal weather, a small creek flows through it. These conditions are ideal for certain “glow worms” which inhabit the walls and roof of the tunnel. While glow worms occur in other dark, damp places in the Blue Mountains, the Glow Worm Tunnel is probably the best place for the visitor to see them. The glow worms are, however, very sensitive to habitat disturbance, in particular: noise, lights, touching and smoke fumes. Wear good walking shoes and take a torch with red light. For us, the return walk from the carpark was about 2h and that included exploring the canyons to the left on the other side of the tunnel and having lunch.
