The story of this place
Springbrook National Park's Natural Bridge is a basalt arch formed by a waterfall eroding through a lava tube over millions of years. The cave behind the waterfall is home to a colony of thousands of glow worms (Arachnocampa flava) — their bioluminescent blue-green light creates an extraordinary natural light display in the darkness. Photography of glow worms requires extremely high ISO (12800+), a fast lens (f/1.8–2.8) and long exposure (15–30 seconds) on a tripod. No flash is permitted — it permanently damages the glow worms. Night tours operate with guides who restrict visitor numbers. The surrounding Gondwana rainforest provides extraordinary night-sky photography opportunities due to minimal light pollution.
