Weather in Chengdu and Jiuzhaigou in June?

Hi, based on the past weather records, it would be fine during that time, with the termpature range of 13-28C. Due to the big temperature gap between daytime and night, you need take along a jacket to keep warm at cool night. It would shower or rain frequently, so umbrella or simeple rainy gear is needed.

As for homestay nearby, you can find at the nearby village. I suggest you ask the local people about the exact location or if you have a tour guide, tell hime or her about your requirement.
