Wat Hat Som Paen

Wat Hat Som Paen sits on the stream that gives the old tin-mining village of Hat Som Paen its name, about 7km inland from central Ranong along Highway 4005. The temple itself is modest — what draws visitors is the water running past it, home to a protected population of pla phluang, a soft-shelled mahseer carp that locals consider sacred and have never fished.

The fish are the reason most people make the trip. Dozens, sometimes hundreds, of pla phluang crowd the shallow stream beside the temple grounds, and feeding them is the main activity — vendors nearby sell ripe red watermelon, which the fish clearly prefer over standard fish pellets. Watching a knot of carp surge toward a thrown chunk of watermelon is as close as this temple gets to a spectacle, and it’s a genuinely low-key one: no queues, no tour buses, just a village stream and a Buddhist community that has protected these fish for generations. Beyond the water, the temple grounds hold a hexagonal chedi thought to be more than a hundred years old and a small memorial hall enshrining a statue of Luang Pho Khlai, a monk widely respected in Ranong who lived out his final years and died at this temple.

Ranong is Thailand’s wettest province, and afternoon showers are routine here for much of the year — the temple stays open through light rain, but the stream can run higher and murkier after a heavy downpour, which makes the fish harder to see clearly. Mornings tend to be calmer and drier.

Insider Tip: Buy watermelon from a vendor right at the stream rather than bringing food from town — it’s what the fish actually go for, and the sellers here rely on that trade.

Dress modestly, as at any working temple: shoulders and knees covered, shoes off before entering any building. This is a functioning village temple rather than a tourist site, so keep noise down and follow the lead of local visitors making offerings. Hat Som Paen’s other draw is the old mining village itself — the Ban Hatsompaen Community nearby runs weekday-morning demonstrations of traditional boat-building and bamboo basketry, and pairs naturally with a temple visit since both sit in the same small settlement.
