Rotorua is known as the thermal wonderland of New Zealand. There are numerous geysers and hot springs in and around the city. Many of these are in parks and reserves. Natural eruptions of steam, hot water and mud occasionally occur in new locations. Nearby Wai-O-Tapu is also a popular tourist attraction with many hot springs noted for their colorful appearance, in addition to the Lady Knox Geyser.
