RealNZ Te Anau Glowworm Caves offers visitors a captivating underground experience. The journey begins with a scenic cruise to the western shores of Lake Te Anau on one of their purpose-built vessels. At Cavern House, guests can explore informative displays about this geological wonder before joining a guided tour of the caves. Friendly guides highlight key features and share the history of the caves. These caves, though relatively young at 12,000 years, are still being shaped by the river that flows through them, creating a network of limestone passages, whirlpools, and a roaring underground waterfall. Deep within the caves, visitors board a small boat to a silent grotto illuminated by hundreds of glowworms, unique to New Zealand. In the darkness, their glittering display is truly extraordinary.
