Sky Mirror is the name given to an island that appears during low tide and reflects a mirror image of the sky. From mid to late morning, a sand bank form and create a shallow Island with a few inches of seawater. The effect creates a mirror image of the sky and any subject standing there, which attracted thousands of locals to capture those fantastic images.
