How high is the temperature in Chengdu in July and August? Is it suitable for playing? Is it too hot to have an appetite?
However, I suggest that you take Chengdu as a transit point and arrange your trip mainly at tourist attractions near Chengdu, such as Qingcheng Mountain, Siguniang Mountain, Emei Mountain, Dujiangyan, Panda Base and so on. These scenic spots are not too far from Chengdu, and they are all summer resorts or famous mountain scenic spots, which are very suitable for summer travel. You can consider going to Chengdu for two days, mainly to eat snacks such as Kuanzhai Lane and Jinli in urban areas with Chengdu characteristics, or to park-like attractions such as Du Fu Caotang and Qingyang Palace. These scenic spots in Chengdu are all in the urban area, which can represent the history of ancient Chengdu. They are shaded by trees and are relatively less hot. You can consider going to a nearby scenic spot another time.
However, I would like to remind you that July and August are summer holidays, and there are many hotels and scenic spots. Hotels should be booked in advance. First, the price should be well controlled, and second, in case they cannot be booked.
I hope I can help.
