Tongpanyu
- Introduction：
- Tongpanyu is the first stop of the southern sea tour. Tongpan looks like a plateau from afar, and its huge basalt columns on the eastern, southern, and western sides earned it the name of “Penghu’s Yellowstone Park”. The abrasion platform on the southwestern tip of the islet reveals its lotus shape during ebb tide. This is actually the mouth of an underwater volcano.
