Our trip plan for this July (married couple 30 ) is to start in Chengdu (4 nights) and go through Jiuzhaigou or Song-pan to Xiahe/Labrang. If we want to experience a part of the beauty between Sichuan and Gansu provinces how many days it will take us to get to Xiahe if we stop on the way. Where to stay? Wont' the roads be in bad condition on Gansu border and dangerous in July? Wont it rain too much in beginning of July?
