Koh Poulo Wai: Introduction

Mon, 17 Aug 2026 00:00:00 GMT

Say the name slowly and it begins to repeat itself. Koh is Khmer for island. Poulo arrived from Malay, a cousin of the Cham word pulo, which also means island. Somewhere in the long traffic of traders, fishermen, mapmakers and colonial surveyors crossing the Gulf of Siam, each new arrival heard the local word for what he was looking at, assumed it was part of the name, and bolted his own word onto the front. What survives on the charts is a stacked redundancy: Wai Island Island. Nobody lives out here to object. Ninety-five kilometres southwest of the Cambodian coast, two wooded ridges break the surface of open water, uninhabited and rock-fringed, far enough from anywhere that the twentieth century largely overlooked them - until four days in May 1975, when this became the most closely watched patch of sea on Earth.

The Wai Islands add up to less than four square kilometres of land - 3.9, to be exact - strung along 14 kilometres of coastline. Each island runs roughly five kilometres end to end and never exceeds about a kilometre and a half across, so from the air they read as a pair of green...

On 12 May 1975, twelve days after Saigon fell, the American container ship SS Mayaguez was steaming through these waters. At 14:18 a Khmer Rouge Swift boat closed on her, fired across her bow, then fired a rocket-propelled grenade. Captain Charles T. Miller sent an SOS and stoppe...

Mon, 17 Aug 2026 00:00:00 GMT

Barely a month after the Americans left, the islands changed hands again. Vietnam People's Army forces seized the Wai Islands in June 1975, and Khmer Rouge and Vietnamese troops fought each other over ground the two movements had been nominal allies on weeks earlier. The Vietname...

Koh Poulo Wai: Sleeping Over

Mon, 17 Aug 2026 00:00:00 GMT

For decades afterward, the Wai Islands were simply off-limits. That has eased. Organised excursions now run out from the Cambodian coast, though the distance imposes its own rule: 95 kilometres is too far to go and return in a day, so anyone who comes has to stay the night. There...
