Since 2003, it has been possible to fly from Chengdu or Chongqing to Jiuzhai Huanglong Airport on a mountain side in Songpan County, and then take an hour-long bus ride to Huanglong, or a 90-minute bus ride to Jiuzhaigou. Since 2006, a daily flight to Xi'an opens in the peak season. In October, 2009, new direct flights were added from Beijing, Shanghai, and Hangzhou. Jiuzhaigou and Huanglong National Parks did not experience any damage during the earthquake of May, 2008, and did not close after the event.
