Ma Shi Chau, literally meaning "horse excrement island", is an island in Hong Kong, under the administration of the Tai Po District.

The peninsula, situated in Tolo harbor, is one of Hong Kong's special geological sites. It is made up of sedimentary rocks formed in the permian period, some 280 million years ago, and belongs to the Tolo harbor Formation.

This area is sometimes dubbed an outdoor geological classroom, due to the many different geological features that are on display.

Besides being educational, the area also has outstanding natural beauty. The rocks themselves have colors that range from pale grey to yellow, red and black, and all is set against the wonderful backdrop of Tolo harbor.

If you go there, proper walking shoes are recommended: no heels or open toes.
