The dark color of the sand is attributed to a high concentration of minerals eroded from the surrounding metamorphic rock mountains.
The site is a major nesting ground for specific migratory seabirds during winter months.
Local authorities frequently issue warnings regarding strong riptides and unpredictable currents along this specific stretch of the Yilan coast.
Ching Shui Beach is a coastal stretch in Wujie Township, Yilan County, characterized by its dark, coarse sand and dynamic Pacific Ocean waves. It serves as a natural barrier where the Dongshan River mouth meets the sea. The beach is part of the broader Lize Coastal Recreation Area infrastructure. The area is marked by a distinctive long, flat coastline that lacks the typical coral reefs of southern Taiwan. Prevailing winds from the Pacific often make the water conditions turbulent and unsuitable for casual swimming. The beach is a popular local spot for observing the sunrise over the Pacific horizon. Coastal erosion is a noted environmental factor influencing the beach's shifting sediment profile. Visitors often access the site through connecting paths from the nearby Dongshan River Water Park area.
