Took this photo at a place called Wai-O-Tapu - Sacred Waters – Thermal Wonderland in Rotorua, New Zealand. Yes this is the colour of the water due to thermal activity, sulphur and other minerals. A lot of the waters around this area are way to hot to even touch. Sculptured out of volcanic activity and thousands of years in the making, Wai-O-Tapu is considered to be New Zealand’s most colourful and diverse geothermal sightseeing attraction. You are introduced to a uniquely different natural landscape – the key to what you see lies below the surface – one of the most extensive geothermal systems in New Zealand. Clearly defined tracks provide the visitor with the opportunity to enjoy the diversity of this area through a series of different walks taking from 30 to 75 minutes or more, each with their own unique volcanic vistas to fascinate all ages.The nature of the reserve being an active volcanic area and the undulating terrain may present some difficulties for people with various disabilities.
