Muang Paeng Hot springs are just 10 kilometres further down the road. They cover an area of approximately 100m by 30m; larger and more impressive than Muang Rae Hot Springs.
Here the water bubbles out of the rocks over the whole area, forming pools and riverlets that flow into a stream. You won't be bathing here!
The stream has a temperature of 80°C. The water bubbling out from between the rocks is, again, over 90°C! The stream flows for about a kilometre, slowly cooling, before it too flows into the Pai River.
