130 Mu 10 Sa Yai Som is a bicarbonate-rich mineral spring in the tenth mu subdivision of Sa Yai Som village, Nong Khai Province, one of the numerous naturally occurring mineral spring sources that emerge across this remarkable geothermal community in northeastern Thailand. The bicarbonate character of this particular spring's water differentiates it from the sulfurous and ferruginous springs at other locations within the same Sa Yai Som geothermal field, reflecting the complex and varied mineralization that characterizes this productive artesian zone. Local residents access the bicarbonate spring water at this address for drinking and bathing, valuing its alkaline mineral character within the traditional Isan knowledge of the community's exceptional natural spring resources.
Insider tip — Positioned in the Sa Yai Som thermal cluster of Kanchanaburi, this bicarbonate spring flows at 38°C amid gentle tropical hillside terrain. The alkaline waters are known to leave skin feeling noticeably smoother after a single soak. This cluster of springs forms a rarely visited thermal zone that rewards those willing to venture off the tourist trail. Bring your own towel and refreshments as facilities are minimal.
