Te Anau Glowworm Caves

Deep beneath the Murchison Mountains, the Te Anau Glowworm Caves are a subterranean wonderland where thousands of tiny glowworms illuminate the darkness like a starry night sky. Accessed only by a scenic boat ride across Lake Te Anau, this guided tour takes you through limestone passages, past roaring underground waterfalls, and into a silent grotto where you drift by boat under the ethereal blue-green glow. It's an intimate, magical encounter with one of New Zealand's most unique ecosystems.

Highlights & What to See

• Boat cruise across Lake Te Anau – a relaxing journey with mountain and lake views setting the scene for the cave experience.
• Underground waterfall – feel the roar of the Cavern Creek waterfall as it thunders through the cave system.
• Glowworm grotto – silently glide by boat through a cathedral-like chamber festooned with thousands of glowworms, their bioluminescence reflecting off the water.
• Interpretive walk – learn about the cave's geology and the life cycle of the glowworm (Arachnocampa luminosa).
• Te Anau township – the departure point, with lakeside dining and walking trails worth exploring before or after your tour.

Suggested Time to Spend

The entire tour, including the boat transfer and cave visit, takes about 2 hours and 15 minutes. Plan for a half-day activity from Te Anau, allowing extra time to enjoy the lakefront or grab a meal. Tours run several times daily, but booking ahead is essential, especially in peak season (October–April).
