The Boiling Heart of the Volcano: A Steamy Journey into Tengchong Rehai Scenic Area

The Geothermal Museum of China

Located approximately 12 to 20 kilometers southwest of Tengchong City in Yunnan Province, the Tengchong Rehai Scenic Area (Hot Sea) is a geological wonder often referred to as a "Geothermal Museum." Situated at the foot of the Gaoligong Mountains, this area sits on the collision zone between the Eurasian and Indian plates, resulting in intense volcanic and geothermal activity. The park covers an area of about 9 square kilometers and is famous for its dense concentration of hot springs, geysers, and steaming ground. Unlike the silent, dormant volcanoes nearby, Rehai is vibrantly alive, filled with the hissing of steam vents and the bubbling of boiling water. It is one of the few places in China where you can witness such powerful geothermal manifestations up close, making it a top destination for geology enthusiasts and travelers seeking a unique spa experience,.

The Big Boiling Pot (Da Gun Guo)

The crown jewel of the scenic area is the Big Boiling Pot (Da Gun Guo). This massive circular pool, with a diameter of over 3 meters and a depth of 6 meters, is a natural boiling cauldron. The water temperature here stays at a scorching 96°C to 97°C year-round, constantly churning and emitting thick clouds of steam that rise into the sky. Standing on the viewing platform, visitors can feel the heat radiating from the earth, a visceral reminder of the volcanic power beneath their feet. A popular activity here is the "Hot Spring Boiled Eggs." Locals sell strings of eggs wrapped in straw, which visitors can place in designated vents surrounding the pot. Within minutes, the eggs are cooked to perfection by the natural steam, absorbing a unique mineral flavor that makes them a must-try delicacy,.

A Symphony of Springs

1.Beyond the Big Boiling: Pot, the park is dotted with over 80 hot spring groups, each with its own unique character. Pearl Spring (Zhenzhu Quan) features hundreds of tiny jets of steam and water bursting from the ground, resembling strings of boiling pearls. Toad Mouth (Hama Zui) is a geyser shaped like a toad; it rhythmically shoots jets of hot water into the air, creating a spectacle that looks like a breathing creature. There is also the Pregnancy Well (Huaitai Jing), surrounded by local folklore suggesting its waters aid fertility. The landscape is a surreal mix of lush green vegetation and white steam, creating a misty, fairyland atmosphere, especially in the early mornings or after rainfall,.

The Ultimate Spa Experience

Tengchong Rehai is not just for sightseeing; it is a premier wellness destination. The Rehai Bath Valley (Yu Gu) and Beauty Pool (Meinv Chi) utilize the natural geothermal waters for therapeutic bathing. The water here is rich in minerals like sulfur and radon, believed to help with skin conditions, arthritis, and fatigue. The resort offers a variety of pools with temperatures ranging from 40°C to 60°C, nestled amidst the forest. A unique local therapy involves a "steam bath" where pine needles and medicinal herbs are laid over steam vents; visitors lie on top covered by blankets, allowing the herbal steam to detoxify the body before rinsing off in the hot pools. This combination of natural beauty and healing waters offers a profound relaxation experience,.
