Sembawang Hot Spring

Sembawang Hot Spring occupies a modest but genuinely extraordinary position in Singapore's urban landscape: a natural geothermal spring in one of the world's most densely developed city-states, preserved and opened as a public park in the residential Sembawang neighbourhood of the island's north. The source is among the very few natural hot springs found in the lowland tropics of Southeast Asia, making it a geological curiosity of considerable significance.

The sulfurous water rises at a remarkable 70 °C — hot enough to cook eggs, as local tradition attests — and is dispensed from taps and channels into foot-bathing pools cooled to safe temperatures for visitors. With a near-neutral pH of 7.5, the water is pleasant on the skin and carries a faint mineral warmth that persists after soaking. The park is free and open to all, and the sight of Singaporeans gathering to soak their feet, sharing the heat of a natural spring in a gleaming modern city, gives Sembawang a warmth that goes well beyond its 70 degrees.
