On New Zealand's North Island, nestled in the green hills of a quiet farm region, lies a unique natural wonder. Guests from all over the world have been coming to admire a world-class spectacle in the Waitomo Caves for more than 130 years. Because they are filled with a magical blue glow that seems to come from another world. In reality, however, there is a completely earthly phenomenon behind it.

One can rightly say that hardly any place in the world is as blessed with breathtaking nature as New Zealand. Ever since director Peter Jackson spectacularly captured his homeland on celluloid in the “Lord of the Rings” trilogy, tourists from all over the world have been flocking to the two islands in the Pacific. However, one of the biggest tourist magnets of all, which has been attracting visitors in droves for more than 130 years, lies underground here. We're talking about the Waitomo Caves in the North Island farming region of the same name. Because here you can observe a unique, almost unearthly beautiful natural phenomenon.

Anyone who visits the Waitomo Caves in the New Zealand summer, from December to March, will witness a magical spectacle. Then the sandstone grottoes are illuminated with the glow of fairy blue lights. They are therefore repeatedly referred to online, even on New Zealand's official tourism website, as "glowworm caves". But it is not these special insects that create the unique effect that is reminiscent of the shine of the stars on a clear night. As the “BBC” reports, the animals are actually the larvae of the fungus mosquito Arachnocampa luminosa. And these produce their turquoise blue light for a simple reason.

This is because they attract prey. The glow, which seems magically beautiful to us humans, is intended to suggest to the victims of the mosquito larvae that it comes from the night sky. In this way, the hunters capture flies, other mosquitoes and even snails, which get caught in the sticky threads of Arachnocampa luminosa. There is no danger to people from the small insects, so you can enjoy the natural spectacle without worry when you tour the Waitomo Caves. And it is precisely this phenomenon that made the cave system, which consists of more than 300 of the over 30 million year old grottos, a tourist magnet in the last century.

According to the attraction's official website, Maori Chief Tane Tinorau discovered the Waitomo Caves in 1887. Together with an English surveyor, he floated through the underground network on a raft on the Waitomo River and also explored parts of it on foot. He was perhaps the first person ever to witness the luminous spectacle, which visitors today are just as amazed at as they were back then. Just two years later, the man opened the caves to paying guests for the first time. It was such a resounding success that the government took over his business in 1906. It was not until 1989 that the land was returned to the descendants of the explorers. Many of the employees who organize the cave tours today belong to Chief Tinorau's family.

If you want to visit the Waitomo Caves today, you can choose between three caves that are open to visitors. The most popular is certainly the “Waitomo Glowworm Cave”. This is where you can best observe the magical glow. It is also the cave system that the chief first discovered. In the “Ruakuri Cave” you can also marvel at impressive rock formations in the form of stalactites. According to the operator, it is also the only cave in the southern hemisphere that can be explored entirely in a wheelchair. The “Aranui Cave” is characterized by its stalagmites and stalactites. However, there are no “fireflies” to marvel at.

In addition to a tour that explores the Waitomo Caves both on foot and by boat, there are also numerous other options. During “Blackwater Rafting” you can float through the caves on a tire or abseil down into the abyss of one, well secured. If you prefer to explore the region above ground, you have the opportunity to do so on a one-kilometer-long zipline course. In its own visitor village you have the opportunity to fortify yourself in numerous restaurants, cafés and bars. If you want to combine your visit with another extremely popular attraction, you can visit Matamata, the “real” Shire from the “Lord of the Rings” films.

For guests who want to stay longer in the region, there are also various accommodations around the Waitomo Caves to suit every budget. The underground tours have different lengths and prices. Please find these on the official provider website. However, booking in advance is highly recommended due to its immense popularity. It should also be noted that the caves and other attractions have different opening times. In the Maori language, the name Waitomo means “water flowing through a hole”. A pretty modest name for such a spectacular natural wonder.
