Before the trip I checked the forecast and saw 10°C in the daytime, thought it wouldn't be too cold, and figured 3 layers (a thermal top, a sweater and a jacket) would be enough. The morning I entered the park, I stood at the gate at 7:00 shivering, with my phone showing 3 degrees. By the time I reached Long Lake it was 0 degrees. Mountain areas have a huge day-night difference, and the forecast temperature is for the town, not for Long Lake, which is over 1,000 m higher.

Temperatures are for the gate area (~2,000 m). Up at Long Lake or Huanglong it's about 5–8°C lower.
Note:the temperatures above are only estimates. Bring extra warm clothes and dress in layers: if it's cold you stay warm enough, and if it's hot you can take some off.
So which month is Jiuzhaigou the most beautiful?
- Most beautiful:mid October – early November.
- Quiet, cheap, with snow:December – February.
- Lush green, mighty waterfalls:June – August (accepting the rain).
- Avoid:October 1–7 and Chinese Lunar New Year – far too crowded.
Note:If your Jiuzhaigou trip falls in peak season, make sure to booktrain ticket, transport tickets, admission ticketsandhotelearly, about 60 days ahead, so prices aren't too high and there's still availability. Booking close to the date at this time of year often sells out, and tickets can run out within a few hours of going on sale. So if you can book ahead, book early.
What to wear in Jiuzhaigou in autumn (September–November)
The rule:several thin layers that are easy to take off and put on.Mornings are 0–5°C, and walking in the midday sun can get warm.
I wore:
- Inner layer: thermal top
- Middle layer: thin sweater / fleece
- Outer layer: light down jacket (folds small into the backpack)
- Pants: thermal long pants or trekking pants + thermal leggings underneath
- Wool hat, scarf, thin gloves (touchscreen compatible)
- Sneakers/trekking shoes with good grip
Winter (December–March)
Thick down jacket, 2 layers of thermal pants, waterproof shoes, heat patches. The boardwalks have ice and are very slippery.
Spring & summer (April–August)
Waterproof windbreaker, thin long-sleeve top, folding umbrella or rain jacket. Still bring 1 warm top for the morning and for going up to Long Lake.
Don't forget the small things
Besides clothes, there are a few things I felt miserable without:sunscreen + lip balm(the highland sun is harsh and the air is very dry),a power bank(batteries drain fast in the cold) anda thermos. The full checklist – documents,eSIM, apps, medicine, preventing altitude sickness – is gathered in the articlewhat to prepare for Jiuzhaigou.
