Pa Tueng Hot Springs

Pa Tueng Hot Springs is a geothermal park in Mae Chan District, Chiang Rai, where a natural geyser erupts roughly 10 metres into the air. When steam drifts into direct sunlight, it produces a visible rainbow — a genuinely striking natural spectacle that draws locals, school groups, and independent travellers alike. The atmosphere is unhurried and authentic, with none of the commercial polish found at more developed hot springs destinations in northern Thailand.

Visitors can soak in free outdoor hot spring pools, boil eggs directly in the warmest vents, and feed carp in a small lakeside area within the park grounds. For those wanting more privacy, paid private onsen rooms are available on-site. A river dam situated nearby provides a scenic backdrop that is particularly popular for photographs. The combination of geothermal activity, open green space, and wildlife gives the site broad appeal — it works equally well as a family outing or a relaxed stop for travellers passing through the region.

The public pools are free to enter, while private onsens carry a fee — confirm current pricing on arrival, as no official website exists. Opening hours are unconfirmed, so it is advisable to check locally before making the trip. The site sits in a rural location, making personal transport or a hired driver the most practical option for getting there. Visiting between November and February allows travellers to enjoy the warm water against cooler air temperatures. Bringing a swimsuit, a towel, and a few eggs is the best way to experience the springs as locals do.
