Wu You Ku is a natural pool formed by tidal influences on the coast north of the Green Island Lighthouse. The nearby coastline is rocky, and because the seawater is blocked by a ring of reefs, a relatively calm small lagoon is formed. Contrary to the imagery suggested by the name "Wu You Ku," this place not only exhibits intertidal characteristics but also, due to its lagoon-like terrain, the pool is calm and waveless, often shimmering with a beautiful sapphire-like blue-green luster.
