Glowworms are not worms, and five other things people get wrong

It is a fly larva. The light is bait. Hungry ones glow brighter. Adults cannot eat. Six corrections to the things almost everyone believes before they walk into the cave.

Hidden gems around Waitomo most visitors drive past

A 17-metre limestone arch, a 35-metre waterfall and a free night circuit with glowworms in it. The half of the district that costs nothing and gets ninety minutes of attention.

How the cave air is monitored, and why tours can stop

Half a million people a year breathing inside a limestone chamber is a measurable problem. Sensors, a carbon dioxide ceiling near 2,400 ppm, and a tour that can be halted.

How the caves went back to their owners

Taken into government administration in 1906, returned to the descendants of the original owners in 1989. The part of the Waitomo story that rarely makes the attraction pages.

Is New Zealand's North Island worth it?

The South Island gets the postcards. The North has the caves, the film set, the geothermal country and the shortest drives between them. An honest case, with the numbers.

One day in Waitomo, realistically

An hour-by-hour plan for a full day in the district, what it costs, and the honest version for people who only have ninety minutes and a car to get back into.

The 1887 first descent, by candle and flax raft

A Māori chief and an English surveyor floated into the Waitomo Stream on a raft of flax stems carrying candles. What they found became the country's most visited cave.

The Cathedral, and the moment people actually remember

A domed chamber on the walking section with acoustics good enough that guides sing in it. Reviewers mention it more than the boat, which says something about the tour.

The quietest time of day to go

Seventeen departures a day, and they are not equal. Where the coach traffic sits, why the first and last slots are calmer, and what a quiet tour actually changes.

What most visitors wish they had known

Seven things that turn up again and again in four-star reviews, each of them avoidable. The photo ban, the boat length, the green-screen souvenir and the café nobody rates.

What travellers complain about most

Five criticisms repeat across every platform, in the same order, with the review text attached. None of them is that the glowworms are underwhelming.

When the Waitomo River rises

The cave has a river running through it and the boat sits on that river. What sustained heavy rain does to a limestone system, and why the tour still usually runs.

Why your phone cannot photograph glowworms

Even where cameras are allowed, the shot does not work. A faint blue-green point source at 480 nanometres against black rock is close to the hardest thing a phone can be asked to do.
