Quick answer
Zhangjiajie can be spectacular in mist, but rain and mountain conditions affect visibility, trails and transport more than they do in a city.
April–June and September–October, with flexibility
Usually easier for long walking days, outdoor sights and a balanced route.
A tight schedule with no buffer for changing mountain conditions.
Not impossible—just worth changing the order, pace or indoor balance.
Keep it flexible
Grip-friendly shoes, layers, rain protection and a plan B for low visibility.
What the weather changes
City-center weather is not the same as conditions on the mountain; route advice must say where its data represents.
