7 Caves You Can Explore in NZ For FREE Without a Tour Guide
21 MAY 2025
If you’re anything like us, caves have that perfect mix of adventure and mystery. There’s just something about stepping into the dark, seeing twisted limestone formations and seeing glowworms overhead that makes you feel like you’ve stumbled into another world.
We’ve explored a handful of caves across New Zealand from glowworm-covered ceilings to mossy arches tucked away in wild forests and each one has felt totally different. Some are easy to get to while others take a bit more effort (and a torch!) but all of them are worth it.
Here are 7 of our favourite caves and arches you can explore in New Zealand — no guide required, just a sense of adventure and maybe some spare socks incase your feet get wet!

1. Waipu Cave, Northland
Waipu Cave is hands down one of the best places in New Zealand to see glowworms and you we love how you don’t need to book an expensive tour to experience seeing glowworms. Just a short drive from the town of Waipu in Northland, this cave is completely free to access!
The entrance to the cave is a couple of minutes from the carpark and it's easy to get inside the cave. Once you're inside, you can walk around standing up as the roof is so high and you're not squished in at all. If you want to see glowworms, you'll need to head to the back of the cave where it's pitch black and the roof is lower here. The glowworms light up the ceiling like a galaxy of stars which is such a magical experience!
The cave is filled with both stalactites and stalagmites, but one formation really steals the show — a massive stalagmite that looks like it's made of stacked crystal bowls or tiny terraces. It's incredibly detailed and unlike anything we've seen before. We looked at it for ages and were glad we had a torch to see all the details on it.
There’s a little stream running through the cave and you’ll need to do a bit of rock-hopping but it’s all part of the fun. Depending on the amount of rainfall in recent days depends on how high the stream will be but absolutely avoid going after or during heavy rain as the cave can flood - safety first, folks!
P.S don't forget to take a torch!

2. Abbey Caves, Northland
Tucked just outside of Whangarei, the Abbey Caves are a hidden gem that are so wild and unique, it's amazing to think that they are free to explore! There are three caves here: Organ, Middle, and Ivy. We only explored Organ Cave, which is the largest and easiest to access, because we could hear lots of water running into the other 2 caves and we weren't going to risk going inside, especially with two young kids!
The track to the caves winds through farmland and native bush (you’ll even pass loads of cool limestone outcrops along the way). Organ Cave is a real adventure — it's dark, wet and packed with glowworms once you get deep enough inside. You don’t need to go far into the cave to start seeing them light up the ceiling like stars. And the best part? No tour guides, no crowds, just you and your torch!
You’ll be wading through ankle to knee-deep water at times, crouching under rocky overhangs, and navigating slippery boulders so bring a torch or headlamp (it will be pitch black otherwise) and really good shoes as it can be slippery inside. You do need to be able to climb up and down fairly large boulders to get into the cave so give this a miss if you aren't comfortable doing so.
Tips: Bring a solid headlamp (plus a backup torch), wear shoes you don’t mind getting soaked, and only go if the weather has been dry — these caves can flood fast.

3. Rawhiti Cave, Nelson Tasman
Rawhiti Cave is a hidden gem near Takaka in Golden Bay, offering an awesome caving experience without the need for a guide or tour. This cave is renowned for its impressive entrance and distinctive geological formations.
The track to the cave is approximately 2.2 km one way and takes about 2 hours return. When you reach the cave, you're greeted by a massive entrance (about 40 meters wide and up to 20 meters tall), covered with thousands of stalactites and some were bigger than us! Every single person who turned up to the cave said WOOOOOW as soon as they saw it - even kids! You can appreciate the cave from the entrance or head down some stairs to a viewing platform where you can get much closer to the stalactites.

4. Moria Gate Arch, West Coast
Moria Gate Arch in the Oparara Basin is tucked away in the lush rainforest of Kahurangi National Park near Karamea on the West Coast. The arch is made of limestone (as are most of our caves in NZ) and it feels like something straight out of Middle-earth — fitting, since it was named after the legendary gate in The Lord of the Rings!
To get to the arch, you walk through beautiful rainforest where the track leads you to a narrow, rocky entrance where you climb down some stairs (with the help of a chain) into the arch itself. Inside, the Oparara River flows beneath the 19-meter-high, 43-meter-wide arch and you can get one of the most incredible, naturally framed photos.
The cave floor is sandy (yes, we made sandcastles) and surprisingly spacious, making it easy to explore along the river’s edge. This is an easily accessible cave which makes it ideal for all ages.

5. Oparara Arch, West Coast
Hidden deep within the ancient rainforest of Kahurangi National Park near Karamea, the Oparara Arch is a colossal natural limestone formation and the largest of its kind in the Southern Hemisphere. Measuring approximately 219 meters long, up to 79 meters wide and 43 meters high, this arch is a breathtaking and it makes you feel so tiny when you stand underneath it.
The walk to the arch is about 1 km, following a well-formed track that take you alongside the Oparara River. The river’s waters are tinged a rich amber hue, stained by tannins from the surrounding forest and we thought it looked like cola!
Once you're inside the arch, you can head down the path to get to the bottom of the cave or just look around from where the path ends. This arch is not too far from the Moria Gate Arch so I'd recommend doing both if you have time!

6. Sumner Beach Cave, Christchurch
This natural sea cave is one of those fun little local gems you can easily miss if you’re not looking for it. Known as Cave Rock, this cave sits in the middle of Sumner Beach in Christchurch and there's no way you can miss it!
The cave is accessible at low tide and it's a short cave (it took us 20 seconds to walk through) which means you don't need a torch as there's loads of light going in. People seem to love climbing on top for the views as well if you're up for a bit of rock climbing.

7. Puanakaiki Cavern, West Coast
Just a short stroll from the famous Pancake Rocks, Punakaiki Cavern is a free and easily accessible cave right off the highway. A wooden staircase takes you up into a natural limestone cavern where you can explore as far as it takes you.
Inside there are stalactites and if you’re lucky (and turn off your torch), you might spot some glow worms twinkling on the ceiling. We didn't go too far in because my phone light wasn't strong enough at all to explore any further so you will definitely need a good torch for this cave. The entrance is quite low and I found myself crouching the futher I went in. There are marine fossils inside the cave that are millions of years old so keep an eye out for these.
It’s a fun, quick stop for anyone wanting a little underground adventure on the West Coast.
