Te Anau Glowworm Caves

Deep beneath the Murchison Mountains on the shores of Lake Te Anau, the Te Anau Glowworm Caves are a subterranean wonderland of limestone passages, underground rivers, and glittering glowworms. Accessible only by a scenic boat cruise across the lake, this guided tour feels like stepping into another world — a dark, silent realm where thousands of tiny bioluminescent creatures create a starry ceiling above you. It’s a magical, humbling experience that showcases New Zealand’s unique natural heritage.

Highlights & What to See

• Boat cruise across Lake Te Anau: The journey itself is a highlight, offering stunning views of the lake and Fiordland mountains.
• Underground cave walk: Follow a guided path through limestone caves carved by the rushing waters of the Waiau River, with dramatic waterfalls and whirlpools.
• Glowworm grotto: Board a small punt to glide silently into the grotto, where thousands of glowworms illuminate the darkness like a constellation.
• Interpretive center: Learn about the cave’s formation, the glowworm lifecycle, and the delicate ecosystem before or after your tour.

Suggested Time to Spend

Plan for a half-day excursion: the full tour (including boat cruise, cave walk, and glowworm viewing) takes about 2 hours 15 minutes, plus travel time from Te Anau township. Many visitors combine it with other Fiordland activities — book a morning or afternoon slot to leave the rest of the day for exploring the lake or Milford Sound.
