Personally, I suggest that it is better to choose some places to play ~ Zhangjiakou Dam and Chengde Dam can be given priority in summer. Chengde has other people's suggestions. I come from Zhangjiakou, where I can give you some advice. There is no good place to go in Zhangjiakou. If you are in the county, you can go to Zhangbei County and Guyuan County on Bashang. The refreshing air, blue sky, white clouds and green grass echo each other from afar and will never let you down. Of course, you should pay attention to sun protection. July and August are the best time to travel in summer. Now Zhangbei is in the period of Tourism Festival, and there are many related national large-scale activities, and there is also a grassland music festival at the end of July. I strongly recommend my opinion to you, hoping to help you.
