Phu Sang Waterfall
Thailand's only warm waterfall, falling into a clear pool that stays 33–35°C all year round.
Phu Sang Waterfall is a single-tier fall about 25 metres high. What sets it apart from any other waterfall is that the water is warm — averaging 33–35°C, clear, and without the sulphur smell of an ordinary hot spring, so you can sit in it comfortably all year round.
The water comes from a warm seep pool that rises from beneath the forest floor a short way above the falls. Spilling over the limestone cliff, it becomes a curtain of warm water that sends up steam on cool mornings — the image that brings people back.
The falls are shaded by dry evergreen forest, with a rest area, a short walking path along the stream, and the Phu Sang National Park headquarters only about 300 metres away — an easy walk.
Highlights
- Soak your feet in the warm pool below the falls
- Steam drifting on cool-season mornings
- Only a 300-metre walk from the car park
Local tipBring a towel and non-slip shoes. Before 10 in the morning there are fewer people and the steam looks its best.

Trails within the site
Collect them station by station
Once you arrive, keep walking the trail. Each station has its own story — you have only finished the trail when every stop is collected.
-
Station 1 · The Great Banyan
A banyan tree decades old whose roots wrap a boulder at the stream’s edge — the first stop on the nature trail. Look up and the canopy closes so tightly that the sunlight comes through in shafts.
Look for small animal tracks in the damp soil around the trunk
-
Station 2 · Listening Point
The point where the waterfall and the stream can be heard at once. Park rangers use it as a stop where visitors close their eyes and listen to the forest for a full minute.
Silence your phone and stand still for a moment
-
Station 3 · Forest Understorey
A shaded stretch where ferns, moss and mushrooms grow on rotting logs — a sign that humidity in this part of the forest stays high all year.
Do not take mushrooms or plants home — leave them for the next visitor
