The park is part of the Datun Volcano Group, an active volcanic region where surface geothermal phenomena are heavily monitored.
The specific mineral composition of the stream includes sulfur, which gives the water a distinct yellow or cloudy appearance.
The area is an essential water catchment and source point for the piping systems serving Beitou's famous hot spring industry.
The heat of the geothermal vents supports a specialized micro-ecosystem of heat-tolerant algae and bacteria on surrounding stones.
Longfenggu Park is a geothermal valley situated within the Yangmingshan National Park ecosystem, known for its volcanic landscape and sulfuric hot spring waters. The park features a network of trails passing through vents that release steam and mineral-rich deposits, showcasing the active post-volcanic geology of the Beitou district. It acts as a primary source for the sulfur-rich hot spring water that supplies many public and private bathing facilities in the surrounding area. Visitors can observe bubbling water and mineral-encrusted rocks along the Longfeng Stream. The site is a managed area under the Yangmingshan National Park administration, maintaining a focus on geological preservation and education. It offers a distinct contrast to the forested mountains nearby, providing a raw view of hydrothermal surface activity.

Bring a damp cloth to cover your nose if the sulfuric odor becomes overwhelming.
Stick strictly to the marked wooden boardwalks, as ground temperatures near the vents are extremely high.
Wear shoes with good grip, as the mineral-heavy water can make paths slippery.
Do not wander into unmarked paths or dense vegetation, as steam vents are often obscured by foliage.
Do not touch the water or step off the path; the ground is dangerously hot and the water is acidic.
