Weather: The weather starts to cool down in September. Average daily low and high temperatures are 11 °C (52 °F) and 21 °C (70 °F) in September. There is about 90 millimeters of total rainfall each September, and precipitation falls on about 19 days of the month. The ultraviolet radiation (UV index) is very high. Consider visiting a summer resort to stay away from the hot weather and to stay comfortable in pleasant weather and beautiful scenery.
Clothing: Wearing leisure clothing and slacks is fine for the daytime. However, if you plan to go outdoors in the early morning or evening or plan to hike up the mountain, bring an overcoat or wind jacket. Wear shoes with good traction when you hike, and take a rain jacket if it seems that rain is likely.
Altitude Sickness: Most visitors experience altitude sickness during an extended stay because most of the park lies between 2,000 meters (6,561 feet) and 3,000 meters (9,800 feet). The airport is at an unusually high elevation of 3,500 meters. To avoid overexertion, walk downhill instead of uphill. Jiuzhai Valley National Park is not recommended for those with high blood pressure or heart disease.
Things to Do
The sky is often bright and clear in September, and then the colorful leaves and tourists are reflected in the multicolored lakes, and red and yellow leaves are sprinkled on the surfaces. By November, it starts to freeze, and the leaves fall off the trees to present stark but beautiful scenery in the higher altitudes.
Hike in Rize Valley: Jiuzhai Valley National Park is incredibly picturesque in autumn when the mountains, valleys, and lakes are shrouded in autumn colors. Warm days, cool nights, and great vistas of yellow, red, and green mixed with blue hues of water create wonderful autumn scenes for hiking. Rize Valley is one of the best places to see fall colors in China. There are colorful carbonate pools.
Visit Huanglong Scenic Area: You can see the valley aflame with fall colors and red maple trees. It is less visited than Jiuzhai Valley. In September, temperatures range between 1 °C (34 °F) at night and a cool 12°C (54 °F) during the day.
High Tourist Season

It is a waste of your time to stand in line in crowded train or bus stations waiting for a possible ticket. Since many hotel rooms in the area don't have adequate hot water, let us help you book your accommodations and transport.
