The 'sinking road' is a result of land subsidence, a common geological issue in the Chiayi coastal region caused by historical groundwater extraction.
The island is technically a sandbar rather than a traditional island, shaped by the shifting currents of the Taiwan Strait.
The location was featured prominently in the award-winning 2019 film 'A Sun' (陽光普照).
The surrounding salt pans date back to the Japanese colonial era when the area was a major center for salt production.
The unique 'flooding road' effect is strictly dependent on the tidal schedule, requiring visitors to check local tide tables for safe access.
Baishuishou Island, located in Dongshi Township, is a coastal area defined by a unique road that gradually sinks into the sea during high tide. The site features an intertidal sandbank accessible only when the tide recedes. It gained popularity as a filming location for the Taiwanese movie 'A Sun'. The landscape is characterized by saline wetlands, oyster farms, and remnants of abandoned salt pans. Visitors navigate a paved path that is partially submerged depending on the lunar tidal cycle. The area serves as a habitat for local coastal bird species. The horizon provides a clear line of sight for sunset viewing over the Taiwan Strait.

Check the local central weather administration tide tables before arriving to ensure the road is accessible.
Wear footwear appropriate for mud and shallow water, as the ground can be soft and slippery.
Bring mosquito repellent, as the wetland environment is prone to insects.
Visit during the shoulder seasons to avoid extreme heat and intense summer typhoons.
Attempting to drive a car onto the path when the tide is rising or the water level is visibly encroaching on the road.
Respect the local fishing equipment and oyster farming gear; do not disturb or walk on active farming structures.
