Hello! Sorry, the bus from Hefei to Zhangzhuangzhai doesn't pass Dangshan. According to the current traffic route planning, it is generally necessary to take G3 Jingtai Expressway or G36 Luoning Expressway from Hefei to Zhangzhuangzhai. Dangshan is located outside these two expressways, so the bus will not pass through Dangshan.

Extended supplement:

If you want to go to Dangshan, you can consider the following ways:

1. Self-driving: You can choose to rent a car or drive a private car to Dangshan, and choose the best route according to the navigation system. Class E needs to start from Hefei and take the G 104 national highway or other suitable roads.

2. High-speed rail+bus: You can take the high-speed rail to Hefei Station first, and then take a bus or taxi to Dangshan at Hefei Station. You can consult the local transportation department or use navigation software to inquire about the bus routes and stations in your home.

3. Charter/tour group: You can also choose to join a charter or tour group to go to Dangshan, which saves you the trouble of arranging your own route and transportation. A professional driver or tour guide will lead you to your destination.

Anyway, if you want to go to Dangshan, Jane suggests knowing the traffic route and mode in advance so as to reach your destination more smoothly. Have a nice trip!
