A few weeks ago a friend in Hazelbrook invited me to see some glow worms near her house. I had never seen glow worms so I was very keen for the new experience. We met at the end of Alexander Avenue where the walk to Horseshoe Falls begins. It was just getting dark and it was winter cold so we had on our thick jackets as well as torches to light the way. Within a few minutes we could hear water cascading and not long after that we saw a path off to the left with a sign to Horseshoe Falls. We didn’t follow that. We kept to the right and headed further down the track until we reached a large rock overhang and a waterfall which I believe is Horseshoe Falls (the signs are a bit confusing!). At first we couldn’t see many glow worms but as darkness set in and our eyes adjusted, our bioluminescent friends started to light up the cave like little stars. It was mesmerising!
Glow worms are unique to Australia and New Zealand and prefer the dark, perpetually damp walls of caves, tunnels and rock overhangs. Glow worms are technically not worms but they are the larvae of predatory fungus gnats. At night they emit a glowing blue-green light from their abdomens attracting other insects for them to eat.
Apart from this cave in Hazelbrook there are other places in the Blue Mountains to observe glow worms including a canyon near Mount Tomah and a tunnel near Lithgow. In order to preserve these magical glowing larvae and their habitats, it is important to follow a few guidelines when visiting them:
- Avoid shining any light directly on them, this includes torches and flash photography.
- Keep as quiet as possible.
- Don’t pollute the air, ground or water of their habitat.
After visiting the glow worms with my friend, I was keen to go back in the daylight and see more of the walk. I am glad I did because it is so beautiful, especially in the morning sunshine. I started down the track and turned left at the Horseshoe Falls sign this time and discovered some falls which I think are called Fairy Falls. Then I found my way back to Horseshoe Falls and the glow worm cave. I stayed there for a while to relax and daydream in the peaceful surroundings.
Just beyond Horseshoe Falls is a sizeable shelter crafted from sticks and bark. Very creative! I wonder who the builder is and if they ever come back to admire their handiwork.
I also discovered there were many more paths to follow and another two waterfalls (Oaklands and Burgess) to find but I had to get home. If only I had all day to go exploring! Ah, next time. Soon.
