How Pai’s four hot springs compare on the ground

• Sai Ngam Hot Spring (18.8 km north-west, 200 THB + 30 THB motorbike — our pick): Sai Ngam is a clear, sandy-bottomed stream stepping down through the forest over low stone weirs, with none of Tha Pai’s sulphur smell. The water comes up through gravel at a comfortable warm-to-lukewarm temperature, so you can sit in the shaded pools year-round. Note that you pay in cash at the sanctuary checkpoint 4 km before the pools, and the final stretch of road has some narrow, steep hills.
• Tha Pai Hot Spring (8.8 km south, 300 THB + 20 THB motorbike): The closest hot spring to town, set inside Huai Nam Dang National Park just off Highway 1095 near the Pai Memorial Bridge. You can walk up to the steaming 75–80°C source to cook eggs in woven bamboo baskets (at 80°C, the yolks set while the whites stay soft), then work your way downhill through a series of bathing pools ranging from hot near the top to lukewarm further down.
• Muang Paeng Hot Spring (32 km south-west, free): Pai’s only free hot spring you can soak in. In a quiet countryside valley along Highway 1265 (45–60 minutes from Pai), a steaming 95–96°C source mounds up through pale travertine rock, feeding a round stone pool and long soaking channels downstream. Eggs are sold at the spring between 6am and 6pm, and for confident scooter riders the countryside drive out is half the draw.
• Pong Dueat Geyser (about 60 km towards Chiang Mai, 300 THB): Tucked into the forest 6.5 km off Highway 1095 (turn-off around km 42), Pong Dueat is the one place where you watch near-boiling 98°C water surge from natural vents before heading back to the ranger station to soak in separate cooled communal pools or hourly private tubs. Because the Chiang Mai–Pai minivans don’t stop here, it’s best for riders and drivers with their own vehicle travelling between Chiang Mai and Pai.

Tickets and same-day passes: which ones share?

• Sai Ngam and Pam Bok Waterfall share a ticket: Both sit inside the Lum Nam Pai Wildlife Sanctuary. Your date-stamped 200 THB sanctuary ticket covers admission to both on the same day, in either order — after Pam Bok, Sai Ngam costs only the 30 THB motorbike fee (or 60 THB for a car) at its gate, so visiting both in one day costs 230 THB total on one scooter (430 THB for two people sharing a scooter). They are on opposite sides of town, though (Pam Bok is 8.2 km south-west; Sai Ngam is 18.8 km north-west).
• Tha Pai and Pong Dueat don’t share a ticket with the sanctuary — or with each other: Both are in Huai Nam Dang National Park (300 THB per foreign adult), so a sanctuary pass from Sai Ngam or Pam Bok doesn’t work at either one, and Tha Pai and Pong Dueat charge separate admissions even on the same day.

Pairing a hot spring with the rest of your day (and going without a scooter)

• South on Highway 1095 (Tha Pai): Tha Pai’s turn-off is near the Pai Memorial Bridge (9.1 km), a few minutes past the turn-off for Pai Canyon (7.3 km), making it easy to pair a morning or early-afternoon soak with sunset at the canyon.
• North-west on Highway 1095 (Sai Ngam): Combine a morning soak at Sai Ngam with the mountain viewpoint at Doi Kiew Lom further up Highway 1095, or ride across town afterwards to use the same day’s sanctuary ticket at Pam Bok Waterfall, with the Kho Ku So Bamboo Bridge just past it.
• South on Highway 1265 (Muang Paeng): About 20 km from Pai on the way out to Muang Paeng, pull over at Muang Rae to see its roadside geothermal well spouting near-boiling water. It’s a quick stop to look at, not somewhere to soak.
• No scooter? Pick Tha Pai: Because Tha Pai is only 8.8 km south of town on the main highway — close to Pai Canyon, the Memorial Bridge, the White Buddha and Two Huts — it’s the easiest spring to reach with a private truck and driver. See our guide to getting around Pai without a scooter.

Before you get in

• Bring a towel and dry clothes, and always test a pool with your hand or foot before stepping in — especially downstream from the 95°C source at Muang Paeng and the 80°C source at Tha Pai.
• Take silver jewellery off at Tha Pai: the sulphur in the water tarnishes silver quickly (and can darken gold alloys too). Sai Ngam has no sulphur smell.
• Bring cash for Sai Ngam: the sanctuary gate 4 km before the pools is cash only. Smoking, vapes and alcohol are banned at Sai Ngam, with posted fines of up to 2,000 baht.
• Take your rubbish home, especially at Muang Paeng, which has no rangers and sits in a working rural community.
