Pikun Thong Royal Development Study Center

Pikun Thong Royal Development Study Center sits 8 km outside Narathiwat town, where researchers have spent over four decades turning naturally acidic peat-swamp soil into farmland. Entry is free, and the centre is genuinely open to the public — not just to visiting farmers on training courses — with an exhibition hall, marked routes between demonstration plots, and staff who talk visitors through the work.

King Bhumibol founded the centre in 1982 after seeing how much of Narathiwat’s peatland — locally called phru, or “sour soil” — sat unused because of its acidity. The 1,740-rai site now functions as both a working research station and a public exhibition. A model and display building explains the lime-and-drainage techniques used to reclaim the soil, and from there marked paths lead out through the working plots: experimental rice paddies, integrated fish-and-livestock ponds, vetiver grass terraces used for erosion control, and smaller herb and mushroom-growing beds. Staff and researchers move between the plots as part of their normal work, and will usually stop to explain what a given trial is testing if you ask.

Insider Tip: Go on a weekday morning. The research plots are actively tended then, and the exhibition staff have more time to talk you through the displays than they do later in the day when the heat sets in.

The atmosphere leans closer to a working farm than a manicured tourist garden — uneven paths, functional signage, no gift shop. That is part of the point: this is Thailand’s actual soil-science operation for the deep south, not a recreation of one. It rewards visitors who want to understand how the region’s agriculture works rather than those looking for a polished photo stop. Pair it with a stop at Thaksin Ratchanivet Palace a kilometre away, or the university-run Sirindhorn Peat Swamp Forest Nature Research and Study Centre, which covers the untouched peat forest the Pikun Thong project was set up to work alongside.

Watch out: Narathiwat is part of Thailand’s deep south, where a long-running separatist insurgency has kept a routine police and military checkpoint presence on rural roads for two decades, and where the UK FCDO, US State Department, and most Western foreign ministries currently advise against all but essential travel to the province. The centre’s location near the provincial capital is a lower-risk area than the southern border districts, but check current conditions before travelling and read the Safety section on the Narathiwat hub page.

Bring a hat, sun protection, and shoes you don’t mind getting muddy — most of the walking is on unpaved farm tracks with no shade. Photography of the grounds and plots is fine; ask first before photographing staff up close. Wildlife spotting is not the draw here, but the Hala-Bala Wildlife Sanctuary further south covers that side of Narathiwat’s nature if research-station visits leave you wanting deeper forest.
