🪨✨ Ngarua Caves, Tākaka Hill, Tasman, NZ
To celebrate our 13th wedding anniversary, we finally visited Ngarua Caves NZ — and WOW. 🤯
It was one of those experiences you almost need to do twice. The first time is so mind-blowing that you need time to process everything you’ve seen… and then you want to go back and properly absorb it all.
Hidden beneath Tākaka Hill is an extraordinary 300-metre cavern filled with delicate stalactites, stalagmites, cave coral, soda straws, flowstone and columns — all slowly shaped by water and minerals over immense stretches of geological time.
The cave is carved into marble roughly 450 million years old, dating back to the Ordovician Period, while the cave itself is estimated to be around 100 million years old. It is believed to have been water-filled during at least the first 20–30 million years of its development.
And there is even more beneath the surface… Recent dye tracing by local speleologists has revealed a small connection with the wider Greenlink system towards the Riuwaka Resurgence.
Discovered in 1876 by 17-year-old surveyor’s assistant Horatio Brewster Everett, the cave was originally known as Hobson’s Cave and became popular enough that people even got married inside!
Photos genuinely don't do it justice. You need to physically experience it to appreciate the scale, atmosphere and incredible beauty of this place. 🩵
A few tips if you visit:
• 🌡️ It’s about 11°C inside
• 👟 Wear sensible footwear
• 👖 Pants or shorts are much easier than a dress/skirt
• 🪜 There are steps, uneven sections and a ladder
• 🦆 There is some ducking and weaving
• 📸 Photography is allowed, but no videoing
• ⛑️ Safety hard hats are provided
• ⏱️ The guided tour takes around 45 minutes
We took our almost-four-year-old daughter and she did really well, although I’d consider the physical requirements carefully for very young children, older visitors or anyone with mobility difficulties.
Ngarua Caves is one of those places that reminds you just how extraordinary the world beneath our feet really is. 🌏🪨✨
