The water at this location is classified as 'green sulfur' spring water, which contains trace amounts of radium found naturally in the volcanic geological formations of Beitou.
The facility was built in 1999 following a campaign by local community groups to preserve public access to the area's volcanic hot springs.
The water pH levels typically range between 1.2 and 1.6, making it one of the most acidic natural hot springs globally.
The tiered pool system uses a gravity-fed design, allowing the hot water to flow downward and cool naturally as it moves through the consecutive basins.
The Beitou Public Hotspring, formally known as the Millennium Hot Spring, is a multi-tiered outdoor public bathing facility that utilizes natural acidic sulfate thermal water sourced from the nearby Thermal Valley. It features four main soaking pools arranged by temperature, ranging from hot to cool, set within a rustic, stone-lined environment. The facility is operated by the Taipei City Government and serves as an accessible, communal version of the region's historic hot spring culture. It is located directly along the Beitou Creek, allowing bathers to experience the natural environment of the valley. The pools are built with natural rock and wood, maintaining a traditional aesthetic despite the modern setting. Water temperatures are managed by mixing the raw volcanic spring water with cold water.

Hydrate well before and after soaking, as the high mineral content and heat can cause rapid dehydration.
Shower thoroughly to remove all soap residue before entering the communal pools to maintain water hygiene.
