Chiang Dao Hot Springs: Pong Arng and the Free Springs Near Town
After a long day of hiking or riding around the valley, there’s nothing I’d rather do than sink into a hot spring. Of all the hot springs I’ve tried in Thailand, the ones in Chiang Dao are still my favorite, and Pong Arng is the one I keep going back to.
This guide covers both Chiang Dao hot springs: what each one is like, how much they cost, how to get there, and when to go. If you’re planning a wider trip, my Chiang Dao guide covers everything else in the valley.
My experience
I’ve spent part of every year in northern Thailand since 2017, and Chiang Dao is my favorite place in the country. When I’m in town, I’m at Pong Arng almost every day, usually toward the end of the afternoon. I walk around the gardens first, then soak until I’m too relaxed to do anything but head back to my room.

| Setting | Landscaped garden grounds and mineral pools in the forest | Simple, rustic tubs |

| Best for | A long, relaxing soak at the end of the day | A quick soak after the drive up, or on the way to the caves |
How I Spend a Day Around the Chiang Dao Hot Springs
My ideal holiday, and I’ve done this a few times now, is simple: find a nice resort in Chiang Dao, or sometimes a homestay, depending on how spontaneous the trip is. Then I spend the days exploring the valley and the evenings in hot water.
If I’m driving up from Chiang Mai, my first stop is usually the free Chiang Dao hot spring. It’s right near town, so it’s the first thing you pass when you arrive, and a quick soak is the perfect way to shake off the drive. After that, my days follow the same easy rhythm: explore in the morning and afternoon, then head to Pong Arng toward the end of the day.
Some of my best conversations in Chiang Dao have happened in the pools at Pong Arng. I’ve met couples, retirees and solo travelers there, and almost all of them had a real love for slow, authentic travel. I think that’s the kind of crowd Chiang Dao draws in. Once, I got talking to a grandson of Chinese immigrants, who, like me, is second-generation Thai. You don’t get many moments like that at a big resort spa.
Pong Arng Hot Spring: My Favorite in Chiang Dao
The bigger of the two Chiang Dao hot springs, Pong Arng Hot Spring, sits inside Pha Daeng National Park, a protected area of limestone mountains, bamboo forest and misty peaks north of town. Above it all stands Doi Chiang Dao, one of Thailand’s highest mountains, which gives the whole valley its dramatic look.
The springs are fed by natural geothermal activity beneath the mountains, and locals have soaked in the mineral-rich water for generations. The pools range from comfortably warm to very hot near the source, so you can move between them until you find the temperature that suits you.
What makes Pong Arng special is the grounds. You’re not limited to one pool. There’s a quiet, green garden you can wander through, with shaded paths, old trees and small streams. I always take a slow walk around before I get in the water. It sets the mood, and it feels more like a botanical garden than a tourist attraction.
If you’d like more privacy, you can rent a small private room with its own bathtub for a little extra. There are also changing rooms, showers and toilets, and you can hire a towel or swimwear on site if you forgot yours.
Unlike many hot springs in Thailand, Pong Arng still feels calm and local. Most people there are nearby residents or travelers who took the time to explore the valley properly.

The Free Hot Spring Near Chiang Dao Town
If you don’t have time for the drive north, the second of the Chiang Dao hot springs is a free public hot spring just outside town. It’s on the way to the caves, so it’s easy to stop by soon after you arrive.
It’s more rustic and basic than Pong Arng, with simple tubs and no garden grounds, but it’s a great place to soak and stretch your legs after the long drive up from Chiang Mai. Pair it with a visit to the Chiang Dao caves further along the same road.
How to Get to the Chiang Dao Hot Springs
From Chiang Mai to Chiang Dao: Chiang Dao town is about 90 minutes north of Chiang Mai by road. You can drive yourself, take a private driver, or catch the public bus north from Chiang Mai’s Arcade Bus Station. The free hot spring is just outside town, so it’s an easy first stop when you arrive.
From Chiang Dao town to Pong Arng: Pong Arng is another 30 to 40 minutes north, inside Pha Daeng National Park. There’s no public transport, so you’ll need a scooter, a car or a private driver. Phone signal can be patchy inside the park, so download an offline map before you set off.
Health Benefits of Soaking in Hot Springs
Soaking in a mineral hot spring combines three things: heat, buoyancy and minerals naturally dissolved in the water. People in Chiang Dao have used these springs for generations, and there’s a reason a soak feels so good after a long day on your feet.
- Muscle and joint relief: Warm water and buoyancy take weight off your joints and ease stiff, tired muscles, which is exactly why I save the springs for the end of a day of hiking.
- Better circulation: Heat widens your blood vessels and improves blood flow. It can also lower blood pressure temporarily, so get out slowly.
- Stress relief: Sitting in warm water helps your body switch into a calmer, more relaxed state.
- Better sleep: Your body cools down after a warm soak, which can make it easier to fall asleep that night.
- Softer skin: Minerals such as sulfur and magnesium are often used to soothe the skin, and some people with eczema or psoriasis find mineral baths help.
The minerals in the water: Hot spring water often contains magnesium, linked to muscle relaxation; sulfur, used for generations for skin conditions; and calcium and silica, often associated with healthy skin.
Most of these benefits are about comfort and relaxation rather than a cure, so think of a soak as a reset, not a treatment. Rochester Regional Health has a good overview of what mineral baths can and can’t do.
Hot Spring Etiquette and Safety Tips
Thai hot springs are relaxed, but a few habits make the experience better for everyone:
- Rinse off first. Take a quick shower before getting into the shared pools.
- Wear swimwear. The shared pools aren’t clothing-optional, and a swimsuit is expected.
- Keep your voice down. Most people come here to unwind, and the quiet is part of the appeal.
- Leave the soap and shampoo for the showers, not the pools.
- Test the water first. Temperatures vary between pools, and the water near the source is far too hot to touch.
- Soak in short sessions of 10 to 20 minutes, cool down in between, and drink plenty of water.
- Check with your doctor first if you’re pregnant or have heart or blood pressure problems, since very hot water isn’t recommended.
When to Visit the Chiang Dao Hot Springs
Time of day: I like going toward the end of the day. By then you’re tired from hiking or exploring, and a soak is the perfect way to wind down before heading back to your room. Pong Arng closes at 6:00 PM, so aim to arrive by mid-afternoon to give yourself time in the garden and the pools.
Time of year: November to early January is the best time to visit. The mornings and evenings are cool, which makes hot water feel even better.
Avoid burning season. From roughly mid-January to mid-April, smoke from crop fires blankets northern Thailand, peaking in March. Air quality can become unhealthy, especially for sensitive people. I learned this the hard way in 2021, when the smoke gave me a rash that only cleared after I left the north. Chiang Mai Doctor’s burning season guide explains the health effects in detail.
Rainy season (roughly June to October) is greener and quieter, but the road into the national park can be muddy, so take extra care on a scooter. My Chiang Mai rainy season guide has more tips for traveling the north at this time of year.
What to Bring
- Swimwear and a towel, although both can be hired at Pong Arng
- Cash for entry and private rooms
- Water and a snack, especially if you’re combining the springs with a hike
- A change of clothes, so you can head straight to dinner afterward
Make It a Half Day
Your Pong Arng ticket also covers Sri Sangwan Waterfall, a multi-tiered cascade a short drive away inside the park. Visit the waterfall first, then finish with a long soak. Here’s a short video of Sri Sangwan Waterfall to give you an idea. Closer to town, the free hot spring and the caves make an easy combination on the same road.
For more ideas, see my things to do in Chiang Dao, or follow my Chiang Dao itinerary for a few full days in the valley. Hot springs are also one of my favorite authentic experiences in Thailand, alongside farm visits, cave walks and mountain hikes.
Conclusion
Of the Chiang Dao hot springs, Pong Arng is the one I’d send any friend to: a quiet garden, warm mineral pools and a calm, local feel, all for around 100 THB. If you’re short on time, the free hot spring near town is a great quick alternative. Go late in the day, skip burning season, and give yourself time to slow down.
