Explore a 1 km glow worm cave in New Zealand’s South Island for free, no guide needed.
In terms of free, self-guided adventures, we all know that New Zealand is the place to be. Clifden Caves, however, is a whole other story. It’s honestly hard to believe that this cave is completely free to visit.
Stretching over 1 km underground, Clifden Caves has several long, winding tunnels, and sections of built-in ladder drops. Along the way, you’ll get to see glow worm-lined limestone caverns and hundreds of stalagmites and stalactites!
If you enjoy exploring cave systems, this one is an absolute treat.
How to Get to Clifden Caves
The entrance to Clifden Caves is located on the side of Clifden Gorge Road. Access to this road is found just near the intersection of Clifden-Blackmount Rd and the Ohai-Clifden Highway.
Location: Cave Entry
The best bet is to just plug in the pin found in the map below. Then, once you reach the pin, there is space for your car or camper just on the side of the road opposite the caves.
Rent a car! New Zealand is very safe for motorists & driving is the best way to explore the country. I always DiscoverCars to get the best deals. Or, if you want a camper, I've had good experiences in NZ with Spaceships & Travellers Autobarn.
Glow Worm Cave Entrance
The Clifden Caves entrance is just on the other side of the fence opposite the parking area. You'll find a small DOC signpost just near the entrance.
You will have to walk over the fence in the designated area. Remember to be respectful because Clifden Caves is actually located on private land. It's a testament to the Kiwi landowners that they've decided to keep this cave open to the public! Legends.
The cave entrance itself is large and easily visible once you find the location.
Once you enter, the first few tunnels are large enough to easily navigate without bending over. However, this quickly changes as you'll find out.
Do I Need a Guide to Explore the Clifden Caves?
Clifden Caves does not require an official guide to explore. In fact, when I arrived here, there was no one else around.
However, caving is a dangerous adventure activity that can easily turn south for those who aren't prepared. Remember never to enter a cave following heavy rainfall and to be prepared by bringing the essential safety items listed below.
What To Bring: Essential Safety Items
Here are some DOC-recommended safety items for exploring Clifden Caves New Zealand.
- Torch/headlamp - recommended 2x per person with spare batteries
- Suitable, loose-fitting clothing
- Sturdy footwear
Remember also to let somebody know of your intentions. Beware of falling rocks and try to stick to the marked routes only. Have a plan to come in and out with a set time frame.

Finding Your Way Through The Glow Worm Cave
Shortly after entering the cave, you'll come to the lower entrance. This section is the narrowest and most difficult tunneled section of the entire cave system.
It might seem a little off-putting at first. However, this is pretty much as tight as it gets as it opens up quite a bit once you get further into the cave.
The path is marked out by reflective markers that point the way. Remember to avoid crawling through any unmarked passages to prevent damage to the cave and to avoid getting lost.
What to Expect at Clifden Caves
- Cave Length: 1 km
- Total Time: 1-2 hours
- Difficulty: Easy but can get claustrophobic, only recommended for fit individuals and kids over 12.
Exploring the Clifden Caves was one of the most underrated adventures that I had in the South Island. The caverns and tunnels are epic to explore, with loads of limestone formations to check out.
The tunnels wind back and forth before opening up to several large caverns. It's possible to make your way all the way through the cave system from the entrance and exit at the southern exit. If you do this, you'll have to drop down a few ladders (see map above).
Try to experience the blackout by covering your torch! You'll probably spot some glow worms
Clifden Glow Worm Caves / Titiwai
Clifden Caves is one of many glow worm caves in New Zealand's South Island. This cave is home to a species of glow worm known as Titiwai. These worms are the larvae stage of a species of flies known as fungus gnats.
The glow is used by the larvae to attract prey which they catch in their sticky, glowing threads that you'll spot throughout the cave.
