Discover New Zealand's natural wonder of Waitomo Glowworm Caves on a guided boat trip. Glide by boat through this underground complex, watching millions of tiny bioluminescent insects lighting up the rocky limestone. Explore this cave complex, including a chance to visit the Cathedral Cave on foot. The caves were formed over 30 million years ago and comprise 2 levels. The upper level is dry and includes the entrance to the cave and formations known as the Catacombs, the Pipe Organ, and the Banquet Chamber. On the lower level are stream passages and the Cathedral. Begin on foot as your local guide brings the caves to life with stories about their history. Then, board a boat and marvel at the light display as you glide silently through the starry wonderland of the Glowworm Grotto.
