We participated in Pumpkin limestone caving tour. limestone cave is the most mysterious and amazing cave I have ever seen. The guys, Shintaro san, Miyu san, are also the most amazing people. They’re so kind and friendly. They took a lots of pictures during the tour for us. I highly recommend this tour to you who is thinking to participate in. When you come to Miyako Island, I’m sure that it would be a wonderful trip for you.
