Jingda Mani volcano should be accurately called Batu volcano, because it is located in the area of Jingda Mani, so it is customary to call it Jingda Mani volcano. It is one of the two famous active volcanoes in Bali, and the other one is the Agon volcano. The one reported by CCTV at the end of last year is still active. Batu volcano is located in the central and northern mountains of Bali at an altitude of more than 1700 meters. Next to it is a volcanic lake, Lake Batul. Viewed from close range, the scenery is pleasant and spectacular. The three craters arranged from low to high are clearly visible, which are the marks left by the eruptions. The latest big eruption was in 1984, when our driver, Adan, was in high school. When the volcano erupted, the villages at the foot of the mountain were annihilated by magma, and many people died. Volcanic eruptions produce a large amount of magma, which, after a long period of cooling, forms a large black area and spreads along the crater to the side of Lake Batu. More than thirty years have passed, and now the volcano stands quietly for tourists to see. And this has also led to the development of tourism around, the original villages at the foot of the mountain have gradually increased, and people began to live in the past. With the development and progress of modern science and technology, human beings have been able to predict and sense volcanic activity more effectively, and control the impact of its eruption period in a certain space. The best place to visit the volcano is the highest terrain viewing platform. It is also a cafeteria with a price of RMB 60 per capita. While eating, it is accompanied by scenery viewing. The meals are not good, nor particularly bad, and acceptable. Actually, the volcano is the main place to visit, and the meal is the second.
