Situated along the southern coast of the Fenggui Peninsula in Penghu, this site is renowned for its volcanic geology. Underwater, the dark columnar basalt shelves drop into scattered boulder fields and submerged sea cave openings carved by relentless wave action. Diving here depends heavily on favorable tides, rewarding visitors with interesting swim-throughs and pockets of marine life sheltered within the rock crevices.
