Koh Thas is a new wonderful, natural island resort in the middle of the Pursat river. It's a private island.
(Do not be mistaken with the island Koh Tas near Sihanoukville)
Once Koh Thas was known as O’rumchong Island by the locals. The original name derives from the saying “On Rong Cham” means “I wait for you.”
This name comes from a local folklore love story about a girl who waits for a boy she loves so long that she returns to stone.
More recently the island’s name has changed to Koh Thas because the island is flat and shaped like a tray for serving food. In Khmer culture, food is often
served on a tray during formal occasions to show respect to elders.
The island was opened as a resort in 2009. There many small huts on the island with straw roofs where can relax and eat a variety of rational food.
To visit Koh Thas from Pursat, you must travel five minutes west along National Road 5 heading towards Battambang until you see a large white entrance gate for Oknha Klang Meung historical shrine on the hand side of the road 56 to Veal Veng District. Take a left here and travel through the gate.
After one and a half kilometers you will see the historical shrine. Continue following the red dirt road five kilometers until the road ends and you must turn right or left. Here you should turn right and follow this road for eight kilometers until you see the Koh Thas sign.
At the sign, turn left and go one kilometer until you see the island. The trip should take no more than forty minutes.

A moto ride is six dollars round trip and a Motoreumork ride should be around 15 dollars round trip depending on the numbers of passengers.
In the past the island was known by locals as O’rumchong Island.
To access the island you must cross a narrow suspension bridge that hangs above the Pursat River. One on the island, there are many small huts with straw roofs where you can relax and eat a variety of traditional Khmer food.
If it is a hot day you can swim or rent a pedal boat shaped like a duck or a swan. If you’re on the adventurous side, you can strap yourself into a harness and glide along a cable cord that hangs above the Pursat River.
Overall Koh Thas is a wonderful place to relax and take in Khmer culture.
