Nestled in the mountains of northern Sichuan, Jiuzhaigou Valley is a fairy-tale world of crystal-clear lakes, multi-level waterfalls, and colorful forests. September marks a magical turning point, as summer greenery begins its spectacular transformation. Here’s everything you need to know for a September visit.
Absolutely, yes. September is widely considered one of the best months to visit Jiuzhaigou and is the official start of the autumn high season. The summer crowds thin out slightly after the school holiday peak (July-August), while the legendary autumn colors start to emerge, especially in the latter half of the month. The weather is pleasant, and the scenery is transitioning into its most iconic state.
September offers comfortable temperatures and plenty of sunny days.
● Temperature: Daytime highs range from 12°C to 22°C (54°F to 72°F). Nights can be chilly, dropping to 5°C to 10°C (41°F to 50°F).
● Conditions: Expect crisp, sunny days with low humidity. However, mountain weather is changeable—occasional rain showers are possible, and layers are essential. Mornings can be misty, creating ethereal scenes on the lakes.
● Packing Tips: Pack layered clothing: T-shirts, long sleeves, a warm fleece or sweater, and a windproof/waterproof jacket. Comfortable walking shoes with good grip are a must. Don’t forget sunscreen, sunglasses, and a hat, as the high-altitude sun is strong.
September is a peak tourist month, especially during the Mid-Autumn Festival holiday (if it falls in September) and on weekends. However, it’s generally less crowded than July and August.
● Crowd Level: You can expect significant crowds at popular sites like Five-Flower Lake (Wuhua Hai) and Nuorilang Waterfall, particularly between 10 AM and 2 PM. The park is vast, so strategic planning can help you find quieter moments.
● Tips to Avoid Crowds:
○ Enter the park right at opening time (usually 7:30 or 8:00 AM).
○ Visit top attractions early in the morning or later in the afternoon.
○ Consider taking the shuttle bus to the furthest points (Long Lake or Primeval Forest) first and work your way back, against the main flow of tourists.
○ Weekdays are noticeably quieter than weekends.
As a peak season month, costs are at their annual high, but not as extreme as during National Day Golden Week in October.
● Park Admission: Around ¥169 (approx. $25 USD) for the low season price, but note that prices sometimes transition to the high season rate (around ¥259) in late September. The mandatory tourist shuttle bus inside the park costs an additional ¥90.
● Accommodation: Hotels in Zhangzha Town (the gateway) are more expensive than in spring or winter. Book at least 2-3 weeks in advance for better rates and selection. Expect to pay significantly more for in-park hotels (if available).
● Flights & Train: Flights to Jiuzhai Huanglong Airport (JZH) and train tickets from Chengdu should be booked early. Prices are stable but at a premium.
This is the star attraction of a September visit. The "Cai Lin" (Colorful Forests) begin their magnificent transformation. While the peak colors usually hit in mid-to-late October, late September offers a breathtaking preview. You’ll see a stunning mosaic of green, golden yellow, fiery orange, and early red across the mountainsides, perfectly mirrored in the turquoise and blue lakes. It’s a photographer’s dream.
● Five-Flower Lake (Wuhua Hai): The clear, multi-hued waters are even more dramatic against the beginnings of autumn color on the surrounding slopes.
● Long Lake (Chang Hai): Jiuzhaigou’s largest and highest lake. The deep blue water, surrounded by pine forests and distant snowy peaks, is majestic in the crisp autumn air.
● Five-Color Pond (Wucai Chi): A small but incredibly vibrant pool. Its mineral-rich colors are stunning under the September sun.
● Nuorilang Waterfall & Shuzheng Lakes: The waterfall is powerful, while the series of lakes and smaller waterfalls below (Shuzheng Lakes) are framed by trees starting to turn color.
● Arrow Bamboo Lake: Known for its reflections. The calm water mirrors the changing foliage beautifully in the right morning light.
● Altitude Awareness: Some areas are over 3,000 meters (9,800 ft). Ascend slowly, stay hydrated, and avoid strenuous activity on the first day. Consider altitude sickness medication if prone.
● Book Everything Early: This is crucial for flights, hotels, and even park tickets, which have a daily visitor limit.
● Stay Overnight: Stay in or near the park for at least one night to maximize your time and enjoy the best light for photography.
● Respect the Environment: Stay on boardwalks, do not touch the water, and carry out all trash. This UNESCO site is incredibly fragile.
In summary, September is a fantastic time to experience Jiuzhaigou. You’ll enjoy pleasant weather, witness the early stages of its world-famous autumn palette, and navigate crowds that are manageable with smart planning. Prepare for a truly unforgettable visual feast.
