Muang Paeng Hot Spring sits in the countryside south of Pai, near Ban Mueang Paeng on the road towards Wat Chan. It is Pai's only free hot spring you can soak in.
Also known as: Mueang Paeng · Muaeng Paeng · Muang Pang Hot Springs · โป่งน้ำร้อนเมืองแปง — not the same place as Mor Pang Waterfall, in the hills west of Pai, or Muang Rae, fifteen kilometres along the same road

This is not a polished resort-style hot spring. It is a simple, rural geothermal site: a steaming natural source, mineral-rich water, and small soaking areas downstream where the spring water has cooled enough to enter.
The source itself is around 95–96°C, so be careful when exploring the area, the water is literally hot enough to boil eggs and conveniently, eggs are for sale at the spring during its opening hours of 6am-6pm. The pools and channels farther downstream are where you can soak—always test the temperature first, as it changes with the flow and with cooler water mixing in.
The final approach is signposted and runs through farmland. There is a short walk from the road to the spring.
The source and the soaking areas
The main spring is the most dramatic part of the site. Hot water bubbles up through pale mineral deposits, with steam rising into the air on cooler days.
It is impressive to look at, but it is not where you swim.
Follow the water away from the source and it gradually cools as it mixes with the surrounding stream. This is where you may find simple areas to sit or soak. Check the water with your hand or foot before getting in, and move slowly—the temperature can change over a short distance.
That is part of Muang Paeng’s charm. It feels less like visiting a developed attraction and more like finding a hot stream in the countryside.
Why is the water so hot?
The heat comes from beneath the landscape around Mueang Paeng.
Groundwater moves down through cracks in the granite below the hills, warms at depth, then rises again through faults and fractures in the rock. At Muang Paeng, that heated water reaches the surface and forms the hot spring.
The pale ground around the source is travertine: mineral deposits left behind as the hot water cools. It is a small but visible reminder that the spring has been shaping this spot for a very long time.
You do not need to understand the geology to enjoy the place, but it explains why Muang Paeng feels so different from an ordinary stream or a built spa.
A slower kind of Pai outing
Muang Paeng works well if you want to get out of Pai without chasing another viewpoint, café, or busy attraction.
Come for a soak, look at the steam rising from the source, and enjoy the quiet agricultural landscape around it. It is especially pleasant on a cooler day, when the warm water and mountain air feel like a proper change of pace.
Facilities are basic, so set your expectations accordingly. This is a natural spring first and a visitor attraction second.
Before you get in
Keep away from the main vent and test the water before settling into a pool. Do not assume a spot is safe because someone else is using it; the flow and temperature can change.
Leave the place as you found it. Take your rubbish with you, keep noise down, and remember that you are visiting a rural community rather than a private spa.
