As the ocean cools, we explore six wild thermal spots from the Coromandel to the West Coast where the earth does the heating for you.

As the April southerlies begin to bite, New Zealand’s ocean beaches lose their appeal for all but the most hardened surfers. But for those who value the freedom of the outdoors, winter isn't a time to retreat — it’s a time to head for the hills. When the Tassie and Pacific become too cold for a comfortable dip, our natural hot springs provide a rugged, practical sanctuary.


Beyond the Summer Crowd


The beauty of a New Zealand winter is the silence. While the clothed crowds fight for space at commercial pools, these colder months belong to those willing to do the work to find the real thing. There’s a grounded honesty in sitting shoulder-deep in a thermal stream while the frost settles on the surrounding bush; it’s a direct connection to the land that doesn't require a dress code or a membership fee.


The Wild & Free List: Six Spots to Flick the Switch


To keep your connection to the land alive this winter, here are six locations where therapeutic neutrality is the standard, not the exception.


  1. Welcome Flat (West Coast): The South Island's high-altitude reward. Reaching these pools requires an 18km trek up the Copland Track. Sitting in 40°C water while looking at the snow-capped Sierra Range is the definition of a world-class experience.

  2. Hot Water Beach (Coromandel Peninsula): The DIY sanctuary. While famous for its crowds, winter offers the chance to dig your own private spa in the sand away from the bustle.

  3. Kerosene Creek (Rotorua): The bush-clad classic. A waterfall and stream where the steam and the ponga fronds provide all the privacy you need. It remains a staple for the local community.

  4. Te Puia Springs (Kawhia): The West Coast’s rugged answer to the Coromandel. Located on Ocean Beach, south of the harbour entrance, this spot offers vast iron sands and geothermal seeps perfect for winter solitude.

  5. Te Maire / Naike Springs (Waikato): A truly wild geothermal seep in a pine forest near Port Waikato. No facilities and no managers mean you set your own standards—just be prepared for the raw, "stinky egg" sulphur reality of a wild spring.

  6. Wai-O-Tapu "Hot 'n' Cold" (Rotorua): A basic, roadside thermal stream where a hot spring meets a cold creek. It’s a "back to basics" spot where the water temperature is as varied as the people who visit it. And this list is by no means exhaustive! There are plenty more. Remember - Google is your friend!


The Winter Code


To keep these spots accessible and high-integrity, we follow the basic code:

  • Be Prepared: The walk back from spots like Kerosene Creek gets dark early in winter. Pack a headlamp.

  • The Copland Factor: The 18km hike to Welcome Flat is a serious undertaking. Check the weather and river levels before setting off.

  • Safety First: Keep your head above water. Amoebic meningitis is a real risk in natural springs; don’t let a great soak turn into a disaster.

  • Respect the Space: These are shared treasures. No glass, no rubbish, and make sure you have permission for photos. We protect the privacy of the community to keep the movement alive.

  • And the Golden Rule? First there sets the dress code. If there are clothed people there before you, nine times out of ten they won't mind if you skinny-dip. But it's courtesy to ask.


The Bottom Line


The earth doesn't care about the season or about what you're wearing. Whether you’re digging a hole at Hot Water Beach or soaking under a glacier on the West Coast, New Zealand’s thermal waters are the ultimate way to stay connected to the environment all year round.
