The other week myself and a few friends explored the old and abandon Helensburgh Tunnel (some also call it the Metropolitan Tunnel). The biggest motivation for exploring the tunnel: Glow worms! We arrived at the tunnel at around 11pm and I was not disappointed at all, it was very cool 🙂
The whole area is very muddy and dark so water proof boots and a torch is essential. The other end of the tunnel is fully submerged so it’s not actually possible to walk from one end to the other but it does mean there are tadpoles swimming around even in the puddles outside the tunnel.
