Fang Hot Springs

Fang Hot Springs bubbles up inside Doi Pha Hom Pok National Park, a short walk from the park headquarters in Fang district. The thermal source runs at roughly 90-100°C — hot enough that visitors boil eggs in it — and feeds a series of channelled, cooled pools where the actual soaking happens. Facilities are simple: concrete pools rather than a resort setup, which is most of the appeal.

Steam rises from several pools of varying size, fed by an underground source that’s been flowing here for generations. The water carries a faint sulfur scent typical of mineral springs, and jungle sounds — birds, rustling leaves — fill in the rest. A cool stream runs nearby, so visitors alternate between a hot soak and a cold plunge, a contrast-bathing habit locals swear boosts circulation. Small vendors near the entrance sell drinks and snacks.

The pace here is unhurried. Locals and tourists share the same pools, which makes for more conversation than you’d get at a commercial spa. It’s a working park facility rather than a polished attraction, and that’s part of what keeps it low-key even as Fang and nearby Doi Ang Khang pull in more visitors each season.

Entry runs on the national park’s fee schedule: 300 THB for foreign adults, 60 THB for Thai adults, and the park is open daily from 08:00 to 16:00. One ticket also covers the rest of Doi Pha Hom Pok, including trails toward Thailand’s second-highest summit if you want to make a longer day of it. The springs are a short drive or motorbike ride from Fang town center; arrive early to beat the day-trip crowds coming up from Chiang Mai.

Insider Tip: Bring a towel and waterproof sandals — the concrete around the pools stays wet and can be slippery.

Watch out: Never dip a hand or foot straight into the source pool itself — at 90-100°C it will scald. Stick to the pools where the water has visibly cooled and other bathers are already soaking.
