Hot Water Beach: Geothermal Pools Under the Sand
Located on the eastern side of the Coromandel Peninsula, Hot Water Beach is one of New Zealand’s most visited natural attractions. This beach combines coastal scenery with a rare geothermal experience, where, at low tide, you can dig into the sand and create your own naturally heated pool. It's a popular stop for road-trippers, particularly when paired with nearby spots like Hahei and Cathedral Cove.
Natural Hot Springs Below the Tide Line
Hot Water Beach gets its name from the geothermal springs that filter up through underground fissures in the volcanic rock. These mineral-rich waters, heated by residual volcanic activity deep beneath the earth’s surface, emerge through the sand just a few metres above the low-tide mark. Temperatures can reach up to 64°C in places, so caution is advised when testing the water.
The hot spring area is located at the southern end of the beach, near a rocky outcrop. A sign near the main car park identifies the best zone for digging, and you can rent a spade from the shop by the beach. You’ll need to time your visit within two hours either side of low tide when the hot spring field is exposed.
Surf, Sand, and Scenic Walks
Even if you don’t plan to dig, Hot Water Beach offers a classic east coast setting with golden sand and surf breaks suitable for experienced surfers. The beach faces northeast and is exposed to open ocean swells. Swimming is possible but not always safe, especially near the rip-prone southern section. A Surf Club patrols the area, so stay between the flags.
The beach is 2 km long and suitable for walking. There is also a short walk along the north side of the lagoon at the south end of the beach, with another short walk beyond the southern end of he beach above the rocky coast.
Geological Context
The beach’s geothermal springs are part of the wider volcanic history that shaped the peninsula, including the now-extinct volcanic centre at Whenuakite, inland from the coast.
The heated water comes from two underground reservoirs located about 2 km below the surface. It rises through fractured rhyolitic rock, part of the peninsula’s ancient volcanic foundation. The presence of natural springs so close to the sea is relatively rare globally.
Facilities and Local Services
Parking is metered and available near the main beach entrance. During peak periods (particularly summer holidays), the area can be extremely busy, and spaces fill quickly. Toilets and changing facilities are provided.
Across the road, you’ll find a café, art gallery, and spade hire. Accommodation options include a local holiday park and several nearby lodges or holiday rentals. The beach is undeveloped beyond the main access area at the south end.
How to Get There
Hot Water Beach is signposted off State Highway 25 near Whenuakite. From Whitianga, head south along SH25 for 20 minutes, turning onto Hot Water Beach Road. From Tairua, drive north on SH25 for about 25 minutes. From Auckland, the beach is around a 2.5-hour drive.
Other nearby coastal places to visit include Pauanui, Ocean Beach in Tairua, Sailors Grave, Cooks Beach and Lonely Bay.
