Hujingyu sits seven nautical miles off the coast of Magong City, and takes about 25mins by boat. The seventh largest island in Penghu is flat and low in the center. Rising up on the east and west, with basaltic transverse joints lined up along the steep coast, it creates a magnificent sight. When the tide ebbs, look down onto the sea and you will see shallow, still, and clear water. That is what makes this place, “Hujing Clear Pool”, one of the eight most renowned sights in Penghu.
Speaking of Hujingyu, the legend of “Hujing Sunken City” never fails to arouse people’s interest and curiosity. Legend has it that there is something like a decadent city wall lying at the bottom of the ocean beneath Hujing. There has never been a real answer as to what the truth really is, and there has long been two discrepant theories in the academia. One of the theories is, “The sunken ancient city is the special basaltic columnar joint terrain extended under the sea from Tongpan and Hujing, therefore forming the false impression of a sunken city”. The other theory believes that there must be a reason why it is documented in historical literature, not only is it in the ancient history books, but there are also many local legends regarding this unusual sight. All of this just adds to the mystery of Hujingyu.
