Miyi Longtan Cave, the full length of the cave is 1.8 kilometers, and the altitude is from 1600 meters to 1800 meters. The interpreter said that it is equivalent to walking 70 floors. I will walk in an hour. The entrance of the cave is a glass viewing platform. Go down the mountain and walk two kilometers of mountain roads to see the mountain view. It takes 35 minutes. The cave is flowing, the environment is quiet, and the strange pillars are everywhere.
