Hot pools can only be dug during the two hours either side of low tide when the geothermal springs are accessible on the beach. Outside this window, the springs are underwater. Tide times vary daily, so check local tide charts before visiting. The hot water is most concentrated in a specific zone near Te Puia Springs, marked by steam rising from the sand. Arrive early during peak season as good spots fill quickly. Bring a shovel to dig your pool in the black sand.

The beach can be family-friendly with proper precautions. The hot spring water can be extremely hot, sometimes scalding, so always test the temperature before entering and mix in cooler seawater. Supervise children closely as temperatures vary across the pool and water depth can change. The ocean itself has typical west coast conditions with waves and currents. Avoid digging pools too close to the incoming tide. The black sand can also get very hot in summer sun, so footwear is advisable.
