Helensburgh, NSW, Australia is home to a sequence of historic tunnels, with one being home to a spectacular, but fragile, colony of glow worms.

If you come to visit these tunnels, please treat them with respect. All commercial filming and photography within the tunnel precinct requires a permit, as do commercial tour groups. For more information, please contact info@helensburghtunnels.org.au

THE TUNNEL HAS RECENTLY REOPENED, BUT IT IS WET, MUDDY AND EXTREMELY SLIPPERY.

ENTER AT YOUR OWN RISK ONLY, AND MAKE SURE YOU TAKE CARE.
