Liuhuanggu is the upstream of Beitou's Huanggang River. The valley is about 1 km long and has a width of 80-200 meters. Fumaroles, sulfur vents and geothermal hot springs dot the valley, and the heat rising from the valley form spectacular white smoke filled the valley. This is the source for Beitou's hot springs. Free parking is available as well as trails, pavilions, explaination kiosks, viewing platforms and simple portable toilets.
Longfenggu is located on the west side of Mt. Shamao, the east and southeast side of the Dunxu High School, southeast of Quanyuan Road, and east of Xingyi Road. Nanhuang Creek flows through it and it is the upstream of Tienmu's Huang Creek.
Longfenggu is rich in natural geological topography and landscape, including pyroclastic rock and Mt. Wuzhi's coarse-grained sandstone. Post-volcanic activity remains active here in the form of the many fumaroles sprouting volcanic sulfur gas and natural and artificial hot springs. Many commercial hot spring baths and restaurants have been opened along Xingyi Road.
Yangmingshan National Park Headquarters established a Longfenggu Park here in 2007 with accessible trails, ecology pond, pavilions and toilets, and planted 100 species of native and aquatic plants.
