The 'Yinyang' (Yin-Yang) name refers to the distinct color separation caused by ferric hydroxide particles.
The mineral-rich runoff originates from the abandoned Jinguashi gold and copper mines located in the mountains above.
The phenomenon occurs year-round, though the color intensity can shift slightly with heavy rainfall or sediment agitation.
The nearby coastal road is a popular location for filming and television productions due to its dramatic backdrop.
The site was historically part of the extensive infrastructure built by the Taiwan Metal Mining Corporation.
Yinyang Sea Observation Deck is a coastal lookout point in Ruifang, New Taipei City, renowned for its distinct dual-colored waters. The phenomenon is caused by the natural runoff of iron sulfide-rich water from the historical Jinguashi mining area into the East China Sea. The contrast between the yellowish-brown mineralized water and the deep blue ocean creates a sharp visual divide. The observation area is positioned at the base of the Shuinandong hills, offering a clear vantage point of the coastline. It serves as a visual record of the area's industrial past and environmental history. The surrounding topography includes prominent geological features from the Japanese colonial era mining operations.
The raised viewing platform providing a wide-angle view of the convergence zone between the yellow and blue water currents.
Bring a polarizing filter for your camera to better capture the contrast of the sea colors.
Check the local weather forecast; the contrast is most visible under clear or partially cloudy skies.
Bring UV protection as the observation deck has minimal shade.
Avoid walking onto the rocks near the waterline, as they can be slippery and exposed to unpredictable coastal currents.
