This place is incredibly expensive, and the 20 RMB shuttle bus is such a great deal; I'd probably pay around 40 RMB myself. On the way up, you can see snow-capped mountains from around the world and their corresponding altitudes. The ride takes about 15 to 25 minutes.
Once you're up, you'll see 3-4 interconnected lakes, but there are 7-8 in total. The first 2-3 lakes have a very deep blue color, and the later lakes gradually change to a grayish-yellow hue. I recommend bringing a drone to capture distant views of the lakes, mountains, sky, clouds, grasslands, etc. If it's cold, the scenic area provides a small heated room to wait for the shuttle.
Overall, it's excellent value, beautiful scenery, and the service is excellent.
