The valley provides the raw sulfurous water piped into local Beitou spas for the area's famous hot spring industry.
The acidic environment creates a unique ecosystem where only sulfur-tolerant vegetation can survive in certain zones.
Geological studies classify this site as part of the dormant Tatun Volcano Group.
White sulfur deposits within the valley are high in hydrogen sulfide, responsible for the area's distinct odor.
Sulfur Valley Recreation Area is a protected volcanic landscape in Taipei’s Beitou District defined by active fumaroles and sulfuric steam vents. The area features a network of walking trails that wind through rugged terrain, exposing visitors to geothermal phenomena including steam-emitting rock crevices and sulfur mineral deposits. It serves as a primary source of the acidic, sulfurous waters that feed the public and private hot spring bathhouses found throughout the Beitou region. The valley is characterized by its high concentrations of white sulfur, which stain the surrounding stone and soil. Visitors can observe the raw geological activity of the Yangmingshan volcanic group from wooden observation decks integrated into the trail system. The site offers a visceral encounter with the island's tectonic origins, far removed from urban infrastructure.

Wear sturdy, closed-toe walking shoes to navigate uneven gravel paths.
Bring a face mask if you are sensitive to strong sulfur or volcanic gas odors.
Carry extra water, as the geothermal activity makes the ambient air feel significantly warmer than the surrounding forest.
Do not attempt to touch the water in the vents or drainage channels, as it is extremely acidic and hot.
Stay strictly on marked paths to avoid high-temperature ground vents and unstable volcanic soil.
