The outer reef of Jade Maiden Rock hides an underwater cave about 16 m down, one of the best-known caves among divers on Lanyu. The tunnel runs about 15 m through near darkness with a faint glow of light, and the water outside is clear. The site is entered from the shore beside the ring road.
Also known as 玉女岩外礁, 玉女岩, Yuren Rock.

The dive
Divers enter the water from the small bend in the ring road beside the seaside bar and head for the outer reef of Jade Maiden Rock. Water outside the cave is clear, with visibility reaching about 20 m.
Below the reef at about 16 m lies the underwater cave, a tunnel about 15 m long that is dark inside with only a faint glow of light. The inside is darker and deeper than the open water around it, so divers go in pairs.

Season follows Lanyu: July to October brings stable seas; from November to March the north-east monsoon makes the east and north coasts rough.
