Other months in Jiuzhaigou
Jiuzhaigou's forum calls late May into June a good window — not cold, not hot, less crowded than the famous autumn colors of October, with the whole park turning green and full of blossoms. Regulars flag June rain as fairly regular but usually short-lived, and note the park's high altitude keeps it comfortable even when nearby Chengdu starts heating up toward the end of the month — landslides on the mountain road in are the more practical concern during the rainy stretch.
