Close to the scenic spot will pass through a tunnel, not the usual kind. Strictly speaking, it is a long cave, estimated to be 6700 meters. The wall of the cave is entirely rock, the top of the cave is dripping water, the width of two cars can barely meet, it seems deep and mysterious, but there is a little fear, very stimulating the senses. Passing through the tunnel is the parking lot. Some staff charge 10 yuan for parking. It's very convenient to get tickets. No matter how many people you are, there will be a boat to take you to the island right away. Don't be too good at service. Some of the facilities in the scenic area are neglected, some of the colonnades are mottled with paint, and visitors to Valentine Valley are scarce, making it very quiet. Because it is a dry season, so the feeling of karst streams is not very strong, spring must be another feeling.
