Xidang is a city in Region name.
Xidang is located in the Mekong river valley at the altitude of 2 300 m. As Feilaisi is getting more and more touristy, some people prefer staying in Xidang before starting the Yubeng trek.
There is an 80 yuan entrance fee to go to Yubeng but if you just stay in Xidang you can return the ticket and get your money back on the way out.
There is a local bus from Deqin to Xidang daily at 3 pm and from Xidang back to Deqin at 8 am. The bus takes you to Xidang village, not up to the hot springs, unless there are enough people going up. It's 15 yuan from Deqin to Xidang, add 5-10 to go to the hot springs. Taking a minivan from Deqin is 150 yuan. It is also possible to hike down from Feilaisi.
There is a nice temple (Bajiu) down by the the Mekong river with two large stupas and 108 small ones. Also ruins of an old tower and a walking bridge across the Mekong river.
Don't be fooled by the name of hot springs. There are no pool like springs but there are cottages with showers and the water comes from a hot spring. If the weather is cloudy, it is the only option to have a hot shower as the guesthouses use solar water heaters.
There are a few guest houses in the village.
The public bus to Deqin leaves 8 am from the village.
