Where are the places suitable for traveling with friends in Bazhong, Nanchong, Dazhou and Hanzhong?

I recommend you to go to the Nuoshui River Scenic Area, which is the largest cave in the world and suitable for friends to travel together. Zhongfeng Cave is a multi-level, multi-type, multi-species and multi-form strange karst world. It's worth a visit. Zhongfeng Cave is 300 meters away from the first high-altitude glass plank road in western China. The plank road hanging over the canyon as high as 1000 meters is a special tourist experience. There are also fantastic mazes and the like, which can be experienced incisively and vividly.
