Geothermal reserve and volcanic fountain area are a special wonder of New Zealand. Rotorua is in the geothermal area, as if it were a cloud. There are countless hot springs and mud pools, vapors everywhere, mud jumps, and a strong sulfur smell; the local Huakaleva fountain erupts regularly, and the Optimus water column pours out like a fountain, making it the best landmark in Rotorua. Rotorua was named one of the 50 most visited places in the world by National Geographic. Rotorua is famous for its unique geothermal hot spring landscape. Typical landscape is geysers and boiling mud fields. We did not see geysers, saw boiling mud, the whole geothermal area was steaming and smoky. When we went, we encountered rainy days. It is even more foggy. The scenic spot has Maori living cabins, boats, various wooden carvings with ethnic characteristics, great scenic spots, and will definitely come here in New Zealand. Rotorua has rich geothermal resources, and some hotels have geothermal hot spring pools, making the hotel look white and smog.
