Located in the banks of Tonle San River, Voen Sai is the pleasant little community of Chinese, Lao and Kreung villages. Originally, the town was located on the north bank of the river and known as Virachey, but these days the main settlement is on the south bank. The north side of the river is the most interesting, with an old Chinese settlement that dates back almost 200 years and serveral Lao and Chunchiet villages nearby. It is possible to cross the river for 500r on a small ferry and walk west for a couple of kilometers, passing through a Chinese village, a Lao community and a small Chunchiet area, before emerging on a wealthy Chinese village complete with large wooden houses and inhabitants who still speak Chinese. The site of Voen Sai is about 35km northwest of Ban Lung on an average to poor road. There is an old Soviet bonerattler (20002, two to three hours) that leaves about 7am from Psar Ban Lung, returning some time around midday.
