The trip to the Blue Mountains is to visit the Jenoland Cave, the oldest open cave known in the world. Some people in the same trade participated in the climbing cave activities. We thought that it was inconvenient to take pictures and gave up. Follow the guide in the hole, all kinds of strange stalactites will definitely leave you a deep memory.
The tour guide led the group members all the way, the cave was dark, and every time we visited a scenic spot, the tour guide would light up the lights in one area. If you walk in front of the front of the guide, every time you see all the lights in order, it feels a bit wonderful. All kinds of rocks are so strange in the erosion of water, and the lighting is even more mysterious.
