Koh Poulo Wai
Koh Wai, , also known as Poulo Wai or the Wai Islands, is a group of two small wooded and uninhabited islands in the Gulf of Siam.

History
These islands were part of the basis of overlapping territorial claims between Cambodia, Thailand and Vietnam; the three nations used differing methods of measuring the extent of their territorial waters from the islands.

In May 1975, the area around these islands and nearby Koh Tang was the site of the Mayaguez incident, the last combat action of the Vietnam War, which involved the rescue of the SS Mayaguez.
One month later, Vietnam People's Army forces seized the islands and there was a battle between Khmer Rouge and Vietnamese troops over the control of the islands. Finally, the Vietnamese evacuated Koh Wai in August.

The Koh Wai islands were for a long time off-limits to tourists, but now they can be visited in organized excursions. Since the trip is too long to go and come back in the same day, visitors usually stay overnight on one of the islands.
