Metropolitan Tunnel

The Metropolitan Tunnel, also known as Helensburgh Glow Worm Tunnel, is a disused rail tunnel in Helensburgh, New South Wales. It is a popular tourist attraction due to its glow worm population. It is considered crown land and managed by community group Helensburgh Landcare, who in early 2019, restricted access to the tunnel for the conservation of the glow worm colony.
