Rotorua is a major destination for both domestic and international tourists; the tourism industry is by far the largest industry in the district. The city is known for its geothermal activity, and features geysers – notably the Pohutu Geyser at Whakarewarewa – and hot mud pools. This thermal activity is sourced to the Rotorua caldera, on which the city lies. Rotorua is home to the Waiariki Institute of Technology.
