Namtok Samrong Kiat

Namtok Samrong Kiat drops about 10 metres off a rock cliff in Bak Dong subdistrict, Khun Han district — one of the few waterfalls in Si Sa Ket province that keeps some water flowing through the dry season, which is what actually makes it locally notable rather than any exceptional height. Entry is free, and the site is open daily from 08:30 to 16:30.

The waterfall was originally known as Namtok Pisat (“Devil Waterfall”), named after a Thai Rangers reconnaissance unit nicknamed “Pisat” that once used the site as an operating base. It kept that name until 2006, when the area was developed for tourism and renamed Samrong Kiat after the nearby village. Above the ledge, the stream runs across a flat rock plain before dropping into a pool at the base — the pool is the main swimming spot, shaded by surrounding forest.

Watch out: because this is one of the only waterfalls in the district with dry-season flow, it draws local day-trippers on weekends even when neighbouring falls have dried up completely — expect more company than the remote setting suggests, especially February through April.

Flow is fullest during and just after the rainy season, roughly May through November, when the ledge turns into a wider curtain of water. Even so, the year-round flow is the real selling point here: most sandstone-plateau waterfalls in this part of Isan run dry by February, so Samrong Kiat is a rare dry-season swimming option if you’re touring Si Sa Ket outside the rains.

Insider Tip: if you’re making the trip out to Khun Han district, Huai Chan Waterfall (Namtok Kantrom) is a second waterfall in the same district worth combining into the same day, and Wat Pa Maha Chedi Kaeo makes an easy cultural stop on the way back toward town.
