The hot spring is a small stream and flows downhill through natural bush. There is a good old kiwi corrugated iron changing shed there. Bathers have excavated small smooth rocks to form their own little hot pools that you can sit next to and enjoy the hot water cascading down. It's a very effective way to ease aches and pains after a hard tramp.
The Hamurana Springs are a collection of springs on the site in Hamurana, located on the north east side of Lake Rotorua, the biggest of which is Hangarua Spring.
The spring is fed from the Mamaku Plateau where the water takes up to 100 years to filter through; the resulting water is so pure and clean that it produces a beautiful blue colour while being virtually clear.
