Supplement to the question:
1. Depart from Luoyang, take Luoluan Expressway, cross Mudan Bridge and head south along S238 line, cross Yichuan County and cross Songxian County. When passing through Hecun Township, Songxian County, you will enter the territory of He Yu, Luanchuan, and staying in Heyu Town is not expensive. Then take a bus at He Yu Bus Station to buy a shuttle bus to Tantou Town (you can also buy a shuttle bus to Chongdugou Scenic Area, but there are only two buses every day, 9 am and 3 pm).
2. After returning from the tour of Chongdugou Scenic Area, buy the shuttle bus from Chongdugou to Luanchuan (note that this bus is a new agricultural vehicle and full of people. At least you are the starting station) and then buy a ticket to Laojun Mountain Scenic Area. Ticket price, 7.5 yuan. You can also buy a ticket to Miao Zi Township (the main street in Miao Zi is the entrance of Longyuwan Scenic Area, and the entrance of Laojun Mountain and Longyuwan Scenic Area is on the overlapping route of National Highway 3 12 and Provincial Highway S238). If you choose Laojun Mountain, you can buy a ticket to reach the entrance of Laojun Mountain Scenic Area, and choose to take a cableway or walk. Note that hiking will be very tiring. The main peak of Laojun Mountain is more than 2000 meters.
It is necessary to visit scenic spots. You can choose to take the bus to Luanchuan on the 3 12 national highway in front of the scenic spot and go back to Luanchuan to stay and eat. You can also wait here for the bus from Luanchuan to Luoyang. Note that there are many people on May Day. I suggest you go back to Luanchuan and buy it at the starting station. At least we can solve the seating problem.
4. Regarding the ticket purchase from Luo Yang to Luanchuan, you can choose the ticket window of Jinyuan Station next to the railway station, or you can buy a car at Yiyun Station (listed as the central station, opposite the railway station) to Luanchuan. (Note that there are few trains at the first stop)
