Initially we did not plan to visit Huanglong Scenic Park. From the photos of other reviewers, all the mineral pools look the same. The park is a three-hour taxi ride from Jiuzhaigou and after taking the cable car to the top, you still have to walk for an hour to reach the Wucai Pool ( Five Colour Pool ) behind Huanglong Back Temple. Then you have to walk another 3 hours down to the entrance. On top of that you may suffer from altitude sickness.
We went to the park on Oct 18 after visiting Jiuzhaigou. We left Jiuzhaigou at 7 am and just before we reached the highest point along the route to get to the park, traffic came to a standstill.The stretch of road was impassable because a 2-inch ice had formed on the road. Many buses and cars turned back. Our driver, a Tibetan, persevered. After waiting for about 30 minutes, the road was cleared of ice and snow.
When we reached Huanglong park cable car ticketing station at 11 am, there was no queue at all. By 11.15 am we were in Huanglong Park. Wow ! it was so beautiful. The pine trees on both sides of the plank walkway were covered with snow. The 1 hour walk to the Wucai Pool was so scenic that we did not feel the distance. To me the most beautiful pools are Wucai Pool ( at the top ), Zhengyan Colourful Pool ( one-third of the trail from Wucai Pool ) and Yingpin Colourful Pool near the entrance ( at the base )
