The Gulong Grand Canyon is known as "one water through the three gorges through three mountains and three holes". Originally, I have been entangled in the psychic Grand Canyon and the Gulong Grand Canyon to choose one. Fortunately, I finally chose the Gulong Mountain Grand Canyon to take a rubber boat rafting tour. The length of the Gulong Mountain Grand Canyon is about 6.8 kilometers. On the way, there will be three caves. The bell milk in the cave is mysterious. The air is very fresh along the way. The rubber boat will drive slowly or urgently with the water. The scenery on both sides is a green sea forest. Full of negative ions filled the entire canyon, a complete picture of the original ecology.
