这是九寨沟。10月都好。但第一个星期是国庆节假期,一个7天的假期。所以,非常拥挤。我猜你可以稍后。温度大约是5 - 15度。有点冷。downcoat做好准备。10月15 - 25是最美丽的红叶。不下雨。 As to delicacy, you can try dried yak meat, traditional highland barley wine and Tibetan butter tea. souveniers, you can buy Qiang ethnic minority's emboidery, Tibetain ornaments, like tibetan silver, tibetan knives. Tibetain is a kind of mixed silver, not pure. If it is too expensive, don't buy it. Knives are not allowed to carry to airplane, so don't buy it too. Tibetan herbal medicine is special but not suggesed too. There are several theater at different level having Tibetan songs and dance show. You should pay for them.
