Traveling from Chengdu to Jiuzhaigou is most efficiently done by high-speed train, which takes approximately 2 hours from Chengdu East Railway Station to Huanglongjiuzhai Station and costs around 141 CNY for a second-class seat. Upon arrival at the station, you must transfer to a bus or taxi for a final 2 to 3-hour journey to reach the Jiuzhaigou National Park entrance. Alternatively, you can take a direct flight from Chengdu Tianfu or Shuangliu International Airport to Jiuzhai Huanglong Airport, a journey of about 40 to 60 minutes followed by a 1.5 to 2-hour airport shuttle or taxi ride. For those on a budget, long-distance buses depart from stations like Xinnanmen and Chadianzi, offering a direct but much longer scenic route that typically takes 8 to 10 hours and costs between 130 and 238 CNY. Since the high-speed rail opening in September 2024, the train and bus combination has become the most popular choice for balancing speed, cost, and comfort.
