For people who want to experience the power of Mother Nature while feeling something interesting on their trip, Fongguei Cave serves as a good choice. Located in the periphery of the south-western corner of Magong City, the cave is an air vent for a basalt cape. Because basalt has a more fragile texture and special prismatic structures, the basaltic rocks here disintegrate after waves hit and corrode them for a long time, formulating a sea cave. And because the sea cave is almost an airtight space, every time the waves rush into the cave, air inside the cave will be pressed to release through the narrow air vent on the ground. Don’t underestimate the small basketball-sized air vent. You shall never put your face near it in an attempt to have a better look. Otherwise, when a huge wave should come, the blast coming out from the air vent may hurt you. During the seasons of typhoon and tidal surges, the air vent will even become a powerful fountain, spurting water several stories high.
If you have no intention to venture, you may enjoy a sea breeze, watch the locals fishing valiantly, and even have a casual chat with them. That would also be a rather special experience.
