Submitted by Huangshan Tourism Development Co., Ltd., historically known as Tangquan (Soup Spring), this hot spring is located on Tangquan Road halfway up Huangshan Mountain. As one of Huangshan’s "Four Wonders," it is legendarily believed to have restored Emperor Xuanyuan to youth after bathing, earning the title of "Spiritual Spring." Sourced from beneath Zishi Peak, the clear, odorless, and sweet-tasting water has a stable temperature of around 42°C year-round, with an hourly output of 48 tons. Dominated by bicarbonate, it contains various beneficial trace elements, offering therapeutic effects for multiple illnesses and serving both drinking and bathing purposes.

As a core wellness facility of Huangshan Scenic Area, the hot spring resort features diverse pools—public pools for casual relaxation, private VIP pools, and hot spring villas. Surrounded by green mountains and mist, visitors can admire Huangshan’s iconic pines and exotic rocks while soaking, with distinct seasonal scenery: spring blossoms, winter snow blending with hot spring steam to create a fairyland-like atmosphere. Supporting facilities include hot spring resorts and specialty restaurants serving wellness-themed cuisine that combines local ingredients with thermal health concepts. Adjacent to Huangshan’s hiking trails, the hot spring allows visitors to relieve fatigue before or after climbing, forming the classic "mountain hiking + thermal wellness" route. Its recognition as a pilot demonstration site highlights its exemplary role in integrating alpine hot springs with famous mountain tourism.
