Deep beneath New Zealand’s forested hills and limestone cliffs lies a hidden world of twinkling lights—not stars, but glowworms. These tiny, bioluminescent creatures create an otherworldly spectacle in underground caverns across Aotearoa. Two of the most famous places to experience this natural wonder are the Waitomo Glowworm Caves in the North Island and the Te Anau Glowworm Caves in the South Island. Time to learn about New Zealand’s Glowworm caves.
But which of New Zealand’s Glowworm caves is right for your itinerary? In this guide, we’ll explore both destinations—comparing the experience, accessibility, scenery, and insider tips—so you can decide which underground marvel fits your New Zealand adventure.
🌌 What Are Glowworms, Anyway?
Before we dive into cave comparisons, it helps to know what glowworms are. New Zealand’s glowworms (Arachnocampa luminosa) are unique to Aotearoa, and despite their magical appearance, they’re not worms at all—they’re the larvae of a species of gnat.
They produce a blue-green bioluminescent glow to lure prey into sticky silk threads that hang from cave ceilings. The result? Caverns that resemble a starlit night sky, with thousands of soft glowing dots suspended in silence.
🧭 Waitomo Glowworm Caves – North Island
📍 Location: Waitomo, Waikato Region (approx. 2.5 hrs from Auckland)
The Waitomo Caves are New Zealand’s most famous glowworm attraction and have been hosting visitors for over 130 years. The region actually features several caves, but the main glowworm tour takes place in the Waitomo Glowworm Cave, a series of limestone chambers featuring cathedral-like acoustics and an unforgettable silent boat ride beneath glowing ceilings.
🌟 Highlights:
- Silent boat tour under thousands of glowworms
- Dramatic limestone formations including the “Cathedral” chamber
- Option to add Black Water Rafting or caving adventure in neighboring Ruakuri or Aranui Caves
🧒 Family-friendly?
Yes! Safe, educational, and magical for all ages.
🤿 Adventure option:
Try the Black Abyss or Black Labyrinth tours — guided underground tubing, rappelling, and ziplining through glowworm-lit rivers.
📝 Best for:
- Families and first-timers
- Easy access from Auckland, Rotorua, or Hobbiton
- Combining with other North Island highlights
🧭 Te Anau Glowworm Caves – South Island
📍 Location: Lake Te Anau, Fiordland (2 hrs from Queenstown or Milford Sound)
Located on the western shore of Lake Te Anau, this lesser-known but equally stunning experience is run by RealNZ and involves a scenic boat cruise across the lake before you enter the caves. The glowworm chamber is smaller and more intimate, but the overall tour is less crowded, and the lake setting is breathtaking.
🌟 Highlights:
- Boat cruise across Lake Te Anau included
- Narrow, fast-flowing stream inside the cave adds a sense of exploration
- Smaller group sizes and fewer tourists
- Part of the wider Fiordland experience
🧒 Family-friendly?
Yes! But note that children under 5 are not permitted inside the caves due to safety rules.
🚫 No cameras allowed:
This helps protect the glowworms and ensures a peaceful experience.
📝 Best for:
- South Island travelers
- Those staying in Te Anau, Milford Sound, or Queenstown
- Nature lovers wanting a less commercial, quieter experience

🧳 How to Choose
If you’re visiting the North Island, Waitomo is a no-brainer. Its dramatic chambers, classic glowworm boat ride, and proximity to other must-see spots (like Hobbiton or Rotorua) make it ideal for most travelers. Plus, the added thrill of black water rafting is a huge bonus for adrenaline-seekers.
If you’re exploring the South Island, Te Anau offers a more peaceful, immersive nature experience, perfect for those already heading to Fiordland or Milford Sound. It’s quieter, more intimate, and gives you a chance to connect with the wilderness around you.
Of course, for the ultimate glowworm tour comparison—you could always do both!
💡 Bonus Tips for Glowworm Cave Tours
- Book ahead in peak seasons (Dec–Feb and June–Aug)

- Dress in layers — caves are cool year-round, around 10–12°C
- Ask guides questions! Most are passionate experts and happy to share stories about the geology, glowworms, and Māori legends
