Rotorua is the most famous mud volcano and hot spring area in the southern hemisphere. It is famous for the geothermal wonders. The "gate of hell" geothermal park is the best place to visit the wonders. The "Lord of the Rings" and "Where Daddy Go" are all filmed here. The guide introduced the silver foil, which was the food of dinosaurs in ancient times, and later the Maori found that the silvery leaves on the back of it would glow at night, so they took a section to put a guide and used it to prevent getting lost. Here the eyes are barren, the air is full of a strong smell of sulfur, the smell is smoked, there is no living thing.
