Fodor's Expert Review Aranui Cave
Eons of dripping water have sculpted a delicate garden of pink-and-white limestone here. Keep an eye out for the resident cave wetas; these native insects stretch up to 4 inches in length and have long antennae, but don’t worry—though scary looking, they're very passive and will most likely hide if they sense you coming. Aranui is named after Te Rutuku Aranui, who discovered the cave in 1910 when his dog disappeared inside in pursuit of a wild pig. Today, hour-long tours lead along boardwalks into tall, narrow chambers. Reservations are essential; tours meet in the Ruakuri Reserve car park on Tumutumu Road, 3 km (2 miles) beyond Waitomo Caves Village.
