There is a unique magic to sinking into water that has been naturally heated by the Earth’s core. In New Zealand, a country alive with geothermal energy, this isn’t a rare luxury; it’s a tradition as old as the land itself. It’s the perfect way to soothe muscles after a long hike, or simply to connect with the raw, living energy just beneath the surface.
Beyond the polished commercial spas, there are incredible spots where you can experience this magic in its wildest form. This guide is your key to discovering New Zealand’s best natural hot springs and hot water beaches.
Know Before You Go: Essential Safety & Etiquette
Enjoying these natural wonders comes with a responsibility to be safe and respectful.
CRITICAL SAFETY TIPS:
- Never Put Your Head Underwater: In any natural thermal pool in New Zealand, there is a very small but real risk of contracting amoebic meningitis. This is easily avoided by keeping your head above the water at all times.
- Test the Water Temperature: Geothermal water can be scaldingly hot near its source. Always test the temperature carefully before getting in.
- Stay Hydrated: Soaking in hot water can dehydrate you. Bring a bottle of drinking water with you.
- Protect Your Valuables: Some free pools are in remote locations. Avoid leaving valuables visible in your car.
HOT POOL ETIQUETTE:
- Leave No Trace: This is the golden rule. Pack out everything you bring in. Leave these special places cleaner than you found them.
- Respect the Vibe: If you arrive at a quiet, serene pool, keep your voice down and respect the peace.
- No Soaps or Shampoos: These are natural waterways. Do not use any soaps, shampoos, or detergents in the water.
The North Island’s Natural Hot Spots
1. Hot Water Beach, The Coromandel
- The Vibe: A bustling, world-famous natural phenomenon. Expect a fun, slightly chaotic scene with dozens of people digging and soaking.
- The Experience: This is a surf beach with a twist. Underground thermal rivers flow beneath a specific patch of sand. For two hours on either side of low tide, you can dig your own personal spa pool. The feeling of the hot water bubbling up through the sand as the cool ocean waves wash in is truly unique.
- How to Get There: Located on the east coast of the Coromandel Peninsula, about a 25-minute drive from Whitianga.
- Best Time to Go: You MUST visit within 2 hours of low tide. Check the local tide chart online. It gets very crowded in summer, so try to visit on a weekday.
- Insider Tip: Bring a spade! You can rent one from the local cafes, but it’s cheaper to have your own. Dig your pool closer to the ocean to get a perfect mix of hot and cold water.
2. Kerosene Creek, near Rotorua
- The Vibe: A magical, free, and rustic local favourite. A scene straight from a fairy tale.
- The Experience: A geothermally heated stream flows through lush native bush, creating naturally warm bathing spots. The main pool is at the base of a small, two-metre waterfall, which acts as a perfect natural shoulder massage.
- How to Get There: Located off State Highway 5 between Rotorua and Taupō. It’s a short drive down a gravel road from the highway.
- Best Time to Go: During the day. It’s not recommended to visit after dark.
- Insider Tip: Wear shoes you don’t mind getting wet for the short walk from the car park to the creek.
3. Otumuheke Stream (Spa Thermal Park), Taupō
- The Vibe: An easily accessible and very popular spot right in Taupō town.
- The Experience: Here, the hot, mineral-rich Otumuheke Stream cascades over a series of small waterfalls before flowing into the cool, mighty Waikato River. You can find a spot in one of the rock pools and get the perfect temperature by moving closer to or further from the hot water source.
- How to Get There: Located in Spa Thermal Park in Taupō. There’s a large car park and new changing facilities.
- Best Time to Go: Anytime, but a soak on a cool evening is particularly special.
- Insider Tip: Combine your soak with a walk or bike ride along the scenic Waikato River Trail which runs right through the park.
4. Kawhia Hot Water Beach (Ocean Beach), Waikato
- The Vibe: The crowd-free, wild west coast alternative to the Coromandel’s famous beach.
- The Experience: At low tide, you can dig your own hot pool in the stunning black sand of this remote and beautiful beach. Often, you’ll have the entire place to yourself, with just the sound of the Tasman Sea for company.
- How to Get There: Located on the west coast of the Waikato, near the small town of Kawhia.
- Best Time to Go: Only at low tide. This is a true hidden gem.
- Insider Tip: This is a proper adventure. The experience feels much more raw and authentic than its famous Coromandel cousin.
The South Island’s Natural Hot Spots
5. Welcome Flat Hot Pools, West Coast
- The Vibe: The ultimate backcountry reward. A truly earned soak.
- The Experience: After a long day’s hike, you get to soak in a series of natural, gravel-bottomed pools surrounded by native forest, with spectacular views of the snow-capped Southern Alps.
- How to Get There: This is not a casual stop; it’s a pilgrimage for hikers. Reaching these pools requires a challenging 7-hour, 18km (one-way) hike on the Copland Track.
- Best Time to Go: During the Great Walks season (October – April).
- Insider Tip: You MUST book the DOC hut at Welcome Flat months in advance. It’s one of the most popular backcountry huts in the country.
6. Hanmer Springs’ Free Pools
- The Vibe: A rustic, DIY experience for those willing to explore beyond the main resort.
- The Experience: While the main Hanmer Springs Thermal Pools are fantastic, a short drive and walk can lead you to free, natural hot pools along the river’s edge, such as at Cow Stream. These are basic, rock-lined pools maintained by locals.
- How to Get There: Ask for directions at the local i-SITE visitor centre for the best and safest spots.
- Best Time to Go: A sunny day when the river isn’t too high.
- Insider Tip: This is a true local’s experience. Be extra respectful and be sure to pack out everything you bring with you.
