Deep beneath the limestone hills of Fiordland, the Te Anau Glowworm Caves are a subterranean wonderland where thousands of tiny glowworms create a starry ceiling above an underground river. Accessible only by a scenic cruise across Lake Te Anau, this guided tour offers a rare glimpse into a fragile ecosystem—complete with waterfalls, whirlpools, and a silent boat ride through the Glowworm Grotto. It’s an enchanting, otherworldly experience that feels like stepping into a living planetarium.
Highlights & What to See
- Cruise across Lake Te Anau – The journey itself is stunning, with mountain-framed views of the lake and Fiordland National Park.
- Underground river and waterfalls – Walk through the cave’s limestone passages, past rushing water and a dramatic waterfall.
- Glowworm Grotto boat ride – Drift silently in the dark as thousands of glowworms twinkle overhead, reflecting in the water.
- Cave formations – Stalactites, stalagmites, and sculpted rock walls carved by centuries of water flow.
- Interpretive guides – Knowledgeable guides explain the geology and biology of the glowworms (Arachnocampa luminosa).
Suggested Time to Spend
Plan for around 2 hours and 15 minutes for the full tour, including the 30-minute cruise each way. The cave visit itself takes about 45 minutes. It’s best to book a tour in advance, especially during peak season (October–April). Combine with a morning or afternoon in Te Anau town—grab a coffee and stroll the lakefront before or after your cave trip.
