It is worth seeing. After the car stops, buy a ticket to enter, take the scenic commuter car to Longxu Waterfall, and then walk to Heigou for a total of 5.7 kilometers. It takes nearly four hours to take pictures and take a rest and eat. There are snacks in Shiliyi Pavilion. We went to Heigou and saw the first line and returned. If we still want to go up, we can also take the commuter car. We are the old lady who is almost 60, and I feel that it is okay to walk down, not very tired.
