One of the most beautiful parks in China. Clearly marked trails, and convenient transport. Within the park, there are many memorable destinations - the milk sea, five lakes, cattle farm. The milk sea is the furthest at 9km from the entrance reaching 4700m. The air is fresh, water is pure, and tourists are many. Most are not prepared for the conditions and altitude so the narrow trails are bottle-necked in a colorful assortment of umbrellas. Tourists suck on oxygen cannisters all the way up, but they still cannot keep a decent pace. During the wet season, it rains nearly everyday. There are no restaurants and toilets are few. Be prepared, your fellow tourists will have altitude sickness as I witnessed many people throwing up, and many people sleeping along the trail. Overall, I very much enjoyed my time! (did not get altitude sickness, packed light, used the electric car, drank plenty of water, visited all the parks destinations in one day)Go early morning, finish by 3pm.
