Green Island has some intriguing volcanic-rock formations. The 300m-long promontory called Little Great Wall is the northern wall of the crater of the volcano that formed Green Island. It leads to a pavilion where you can see Haishenping (海參坪, Hǎishēn Píng), the crater bay.
Across the bay is Sleeping Beauty Rock , one of the formations that actually does resemble its name (once you figure out the neck, the rest of the figure will fall into place).
