The gleaming white Hsiyu Lighthouse, located at the island's southwestern tip, guides ships as they ply between Xiamen, Penghu, and Taiwan, and fishermen working the seas to the west of Penghu depend on it in their nighttime operations. The lighthouse is also a great spot for viewing the famous "Hsiyu sunset," considered one of the eight most beautiful sights in Penghu.
