I recently visited this valley in May 2019. The entrance fee inclusive of bus is 90 RMB per person. The bus brings you to a Tibetan temple where you can see the 4 peaks of Siguniang if the weather is clear. Usually, the weather is cloudy and you will most likely miss the highest and 4th peak. The wooden plank walkway is under renovation at some parts and you will have to detour on muddy paths. These paths are not clearly marked and so it is best to use a local guide which was recommended to me by the BnB that I stayed. If you aim to go to Muluozi, hire a horse. It is much faster. The valley is still very pristine and the hike gave me the impression of being in the Swiss alps. Avoid Jun-Aug, the rainy season. As the weather is usually cloudy and changeable, plan to have 3 full days in your itinerary and hope that 1 of the 3 days is clear weather. You can find drinks and food along the pathway, contrary to a previous review, sold by the locals. Common drinks are mineral water, Redbull and food includes instant noodles which the locals heat with boiled water. Avoid the first 2 weeks of October as it is peak travel season for the Chinese.

This place is a nice valley with river streams and waterfalls. The wooden walkway is elevated and the park itself is well-maintained , clean. Shops are not available inside. Bring your own food and there is an entrance fee.
