Fodor's Expert Review Aranui Caves

This is one of the smallest and prettiest cave systems in Waitomo. Eons of dripping water have sculpted a delicate garden of pink-and-white limestone here. Hour-long tours lead along boardwalks into tall, narrow chambers. Keep an eye out for the resident cave wetas; these native insects grow up to 4 inches long, but don’t worry—they will most likely hide if they sense you coming. Tours meet at the Ruakuri Visitor Centre at the top of Ruakuri Reserve on Tumutumu Road, 3 km (2 miles) beyond Waitomo Caves Village. Reservations are essential.
