13 Kēng Wēnquán — '13 Pit Hot Spring' — is a geothermal spring complex in China consisting of thirteen distinct spring pits or pools of naturally warm, mineralised water, numbered and managed as a systematic bathing facility. Multi-pool hot spring complexes of this kind are common across China's thermal resort landscape, where a single geothermal field may produce numerous distinct outlets of varying temperature and mineral composition that are developed into differentiated bathing pools offering a progression of thermal experiences. The 13-pool format allows guests to move through the springs in a sequence, experiencing the range of mineral and thermal characters the field has to offer.
Insider tip — The 13-pool spring complex near Tainan sits in Taiwan's western foothills where geothermal waters rise through sandstone and mudstone layers of the Western Foothills geological zone. At 40°C, the multiple small pools each have slightly different mineral compositions depending on local fracture patterns. This is a local favorite, favored for post-harvest relaxation by surrounding sugarcane farming communities.
