Pong Deuat Pa Pae is located at Pa Pae sub district, Mae Tang district which is part of Huai Nam Dang National Park. It is a vast hot spring or geyser on Mae Tang basin. This power geyser spurts up from under that ground at a very high temperature and high pressure. It can reach as high as 1 -2 meters due to loose soil. There are 3 or 4 main springs and several ones scattering sporadically. The surrounding area features a dense forest and the lingering smell of Sulphur.
The general topography of the area is a large-scale hot spring or geyser. The accumulation of gases underneath boiling hot water causes an extremely high temperature and exceptionally strong compression. Although it may spurt up occasionally or unceasingly, it always reaches its highest spurt at a constant time of the day. The surface temperature is measured around 90 – 99 °C, but on the other hand the underground temperature can be as high as 170 – 203 °C. Pong Deuat Pa Pae is said to be the biggest and highest geyser in Thailand.
