Insider tip — Huoyan Shan Dujiu Jiudian (Flaming Mountain Isolated Hotel) sits in the volcanic geothermal belt of Weishan county, western Yunnan, where deeply circulated groundwater surfaces at 42°C with a distinctive sulfurous aroma. The hotel pools overlook terraced hillside farmland typical of the Yi minority region. Arrive in early spring when the surrounding plum and cherry orchards are in bloom for a magical sensory contrast.
