The milk sea seems to be every Yading Tourist's ultimate goal. From the entrance its a 9km hike, or from luorong cattle farm, a 4.6km hike. It is a gradual ascent to 4700m with a few parts that are treacherous as during the wet season it rains every afternoon and turns the trails into mud rivers. When I visited, it even hailed as I was descending. Despite the conditions, it is a must see. Advice: First, go very early in the morning, and see the milk sea first, then go on to the other destinations within the park. Second, book a roundtrip on the electric car from the entrance to the cattle farm, its only 80元 and beats being stuck in the rain.
