The small train entering the mountain is very interesting. After entering the cave, there are still 100 meters of black. After entering the cave, the tourists who will enter the cave form a group. Some people specially explain, but the content of the explanation is not very much. In the cave, the main thing is to take a small train to see. The lights on both sides of the railway lane are not good, and there is not much to see in the cave. In addition, taking a boat instead of approaching a floating bridge of 80 meters, the light in the cave is not good, and the ripples can be heard. The sound of running water is another feeling. After going up by elevator, I chose to walk down the hill. After walking for 20 minutes, I arrived. I watched the scenery all the way, blew the breeze and went down the hill easily.
