Yuquan Cave is the largest stalactite cave in Okinawa. It has a history of 300,000 years. The tunnel is about five kilometers long. There are many spectacular stalactite groups and stalactites in the cave. The temperature inside the cave is kept at about 20 degrees, so visiting Yuquan Cave is a cool and pleasing enjoyment. But overall, the scale and shape of this stalactite cave is too pediatric compared with some famous caves in China.
