The Kah Bpow river which runs through the town begins in the Cardamoms and runs down to join the Gulf of Thailand. The town's relatively remote location, close to the Cardamoms and the Thai border, has made it the centre of an active wildlife smuggling trade. Much wildlife captured in the Central Cardamoms goes to supply the restaurants and fresh markets in Koh Kong town.
The Kah Bpow river, which passes through the town, originates from the Cardamoms and empties into the Gulf of Thailand. The town's proximity to the Cardamoms and Thai border has fostered a significant wildlife trafficking network. Many animals captured in the Central Cardamoms are transported for sale at restaurants and fresh markets in Koh Kong town.
