Bo Nam Rae Bo Nam Ron

Bo Nam Rae Bo Nam Ron is a working local hot spring in Mai Phatthana subdistrict, Ko Kha district — about 12 km off the Ko Kha-Hang Chat road and a 30-40 minute drive from central Lampang, not inside Lampang town itself despite how the name gets shortened. The source water emerges at around 65°C, hot enough that locals genuinely boil eggs in it, and is cooled into tiled soaking pools and private tubs for bathing.

Two things distinguish this site from the mineral-water pools scattered around northern Thailand: the source temperature is unusually high, and the setup keeps things simple rather than resort-style. There’s a shared soaking pool, private tub rooms of different sizes, and an area where you can boil your own eggs in the hottest run-off water — a small, popular ritual here rather than an official attraction in itself. The water carries the faint sulfur smell typical of geothermal springs, and steam rises visibly off the pools in the cooler months.

Insider Tip: Bring your own eggs if you want to try the boiling pool — it’s a local habit, not a paid activity, and there’s usually a spot set aside near the hottest outflow specifically for it.

Pricing runs on a simple tiered system: a cheaper rate for the shared pool, more for a private tub, generally in the 10-100 THB range depending on which option and how long you stay. That keeps it well below what commercialised hot springs charge elsewhere in the north, though it also means the facilities stay basic — soaking rooms and pools rather than a spa complex, with traditional Thai massage available on-site as an add-on.

Watch out: Facilities are functional, not polished — don’t expect changing rooms or amenities on par with resort hot springs like those near Chiang Rai or Mae Kachan. Bring your own towel.

Traditional Thai massage is available on-site as a paid add-on if you want to extend the visit beyond soaking — a straightforward way to spend a half-day here rather than the quick 30-minute stop some visitors treat it as. Locals tend to treat the springs as a genuine wellness stop rather than a tourist photo opportunity, so expect a low-key, practical atmosphere: functional tiled pools, plastic chairs, and people quietly soaking rather than posing.

November to February is the best window: cooler air makes the contrast with the hot water more enjoyable, and mist rising off the pools in the early morning is the closest this place gets to atmospheric. It’s reachable by car or motorbike from Lampang town, though there’s no public transport directly to the site — a private ride or your own wheels is the practical option.
