We had a wonderful day out visiting the mountains west of Sydney. Since buying our four wheel drive Craig has been wanting to take it off road, so this was our opportunity! We spent about 30 minutes on a dirt track just to get there and being 6 months pregnant I felt every bump :-)
Once we were there it is only a kilometre to the tunnel itself and it's a beautiful walk with caves and water, bridges and stairs along the way.
The tunnel used to be an old train tunnel and when you go inside you can see the black on the ceiling of the cave from where the steam from the train used to hit. Now there are no more tracks and all that is left is the tunnel and the glow worms that have taken up residence there.
As long as you have a good torch/flashlight you can get far enough into the tunnel, turn your torch off and see a see of glow worms. Felicity was fascinated and everyone had a great time even though our torch stopped working just as we got to the tunnel.
