Old Helensburgh Tunnel

Location: Old Helensburgh Tunnel, Helensburgh 

Built in the 1880’s, this abandoned train tunnel is located on the outskirts of Sydney, in the Sutherland.

Walking down the railway tracks towards the tunnel, you can see how overgrown the entrance is, with ferns covering the brick work. Super eerie but really cool.


If you walk down the tunnel far enough you can see a few glow worms light up like blue fairy lights scattered across the walls. We hung out here for about two hours, just exploring..


Remember not to shine your torch towards them and stay silent to see their full potential. We put our camera on long exposure and created different effects with the brightness from our phone screen.

Unfortunately you can’t walk to the end of the tunnel as it is flooded, but there are rumours there is an abandoned steam train that has been there since it closed.


Everything you need to know: 

  • Free entry
  • The carpark is literally a 100 metre walk from the entrance of both tunnels.
  • It does get pretty muddy, so bring old shoes or gumboots.
  • A torch if you are keen to explore the tunnels
