The hot Tengchong Volcano and Geothermal National Geological Park.

Tengchong is a rare area in the world where volcanoes and geothermal coexist. It is said that there are 97 volcanoes in the Volcano and Geothermal Geological Park, among which the Great Kong Mountain and the Small Kong Mountain are relatively complete dormant volcanoes. There are more than 1,000 steps to the Great Kong Mountain, and it takes some effort to climb up. After climbing the mountain, you can walk around the crater. The crater is densely vegetated, and it is difficult to find a good spot and angle for taking photos. The focus is on experiencing the eruption remains of the crater. There are also horse rental services on the mountain. If you visit in the morning, it is recommended to experience a hot air balloon ride. The hot air balloon flies at an altitude of about 200 meters and stays in the air for about 10 minutes. You can see the whole view of the Volcano Geological Park, including the Great Kong Mountain, the Small Kong Mountain, and the Black Kong Mountain, and you can also see the Tengchong city from a distance. After getting off the hot air balloon and returning to the visitor center, you can also check in at the Tengchong Volcano Geological Museum to learn about the principles and structures of volcano formation and other popular science knowledge.
