Ma Shi Chau, Tidal island in Tai Po District, Hong Kong.
Ma Shi Chau is a tidal island in Tolo Harbour within Tai Po District that spans approximately 0.61 square kilometers. It connects to the neighboring Yim Tin Tsai island through a natural pathway that emerges at low tide and becomes submerged when water levels rise.
The location was originally known by a different name before being designated as Ma Shi Chau. Over time it became recognized for its geological importance and is now a site of scientific interest.
The site serves as a learning center where students examine rock formations and discover how marine life shapes the landscape. Visitors can see educational activities and research work taking place around the island.
Visitors should check tide schedules before planning a trip since the connecting path becomes submerged at high tide. Understanding water levels helps ensure safe exploration of the island and access to different areas.
The island contains sedimentary rock formations dating from the Permian period, making it geologically ancient. This draws researchers who study how the earth's crust has changed over millions of years.
