Love Glows Brightest in the Dark - Well Glow-worms do Anyway :D
There is a Natural Wonder in New Zealand that strongly resembles the Cave of Two Lovers. Well, the glowing in the dark part at least.
The Waitomo Glow-worm Caves attraction is a cave at Waitomo on the North Island of New Zealand, known for its population of glowworms, Arachnocampa luminosa. These glowworms are found exclusively in New Zealand and are around the size of an average mosquito. This cave is part of the Waitomo Caves system that includes the Ruakuri Cave and the Aranui Cave. The name “Waitomo” comes from the Māori words wai, water and tomo, hole or shaft. The local Māori people had known about the caves for quite some time before the local Māori Chief Tane Tinorau and an English surveyor, Fred Mace, did an extensive exploration in 1887.
