About the activity

Meeting at our modern Adventure Centre and Cafe, you’ll be equipped with a caving helmet and light.  You’ll join one of our professional and passionate guides, starting your journey into the spectacular Paparoa National Park, right on the doorstep of Charleston.

Following a short drive into the deep canyon of the Nile / Waitakere River, you’ll board the Nile River Rainforest Train for a 20 minute journey into the lush forests of the Paparoa National Park. It’s then just a short walk to the Metro / Te Ananui Cave, climbing high above the river to the cave entrance.

Leaving daylight behind you will explore as the first cavers did: with only the light you bring, and not a a handrail or boardwalk to be seen! It’s truly one of the few natural and “real” guided cave experiences left: seeing, feeling and getting close to an ancient wonderland sculpted by water and decorated with fragile calcite formations.

Underground you will visit such famous formations as The Altar, the highly decorated ‘Hall of Refugees’, Pancake Corner and more, before you emerge back to daylight at the awe-inspiring Main Entrance of the Metro / Te Ananui – having journeyed right through the mountain!

A short rest, then you’ll head back to find the stars of the show: Arachnocampa luminosa: the New Zealand GlowWorm. One becomes ten, then a hundred, then thousands. Before your eyes, entire galaxies of GlowWorms appear, spanning the ceiling over your head, following the streamway into the distance. Your guides will enrich your journey with captivating illustrations, explanations and stories connecting you with this special place.

Returning via the same path, you’ll emerge back to the daylight. A short stroll leads back to the train, then to the comparative civilisation of Charleston.

This is an unique journey that takes you into one of the few publicly accessible cave systems that remain in its state of natural, unspoiled beauty. It’s a simply stunning Eco-tour in a very special place.

* A 10-min drive and a 15 min Train Ride into the Nile River Canyon.
* Walking across the Nile River by suspension bridge and up 131 steps (equivalent to a 6-7 story building) to the cave entrance.
* Walking on natural unformed surfaces, both to the cave, then through the large decorated upper cave passages, where it is possible to slip, trip or otherwise fall, potentially causing injury.
* Traversing several short sections with low ceilings (120-150cm high) that require the participant to be able to crouch and move through, where there is the potential to impact your head (helmets are worn) resulting in bruising, head, neck or spinal injury.
* Climbing a ‘natural staircase’ of approximately 3 stories inside the cave, where the steps are uneven, large (up to 40cm) and potentially slippery, and no handrails are present. There is the potential to slip or fall , resulting in abrasions, breaks to limbs or impact to head.
* Walking through to the large “Main Entrance” and to the Glowworm Colony over a dry river bed involving natural, uneven, unformed surfaces, where it is possible to slip, trip or otherwise fall, potentially causing injury.
* A return walk through the cave of approx. 1.5 km

There are no handrails, walkways or infrastructure inside the cave to assist you. You should therefore be confident with your footing and happy to navigate very uneven surfaces and steps.
