Cha Ong Waterfall locates at the middle of the forest in Cha Ong village, Ou Chum District in approximate two-kilometer distance from the Ban Lung town ty the National Road No. 19 ( Ban Lung-Steung Treng), then turning right by a trail about six-kilometer. We call the waterfall “Cha Ong” because we follow the ethnic minority of Kreung at Cha Ong village closed to the waterfall. The source of this waterfall is coming from the mountain named Ey Sey Park Ta Mak” or called “Phnom Svay” closed to the Ban Lung town.

The situation from about is a small canal which continuously flows through the broken rocks, then to the stream in 25-kilometer height. For viewing the waterfall, we should go down to the stream below where we have seen a big rocky cave with the plain roof. At the bottom of the stream, there are many big rocks use as the seats for viewing the great and interesting water falling down from the mountaintop.
