Cha Ong waterfall is in the forest in Cha Ong village, O’Chum commune, about 2 kilometers west of Ban Loung provincial town. It was given its name by the Kreung hill tribe living nearby.

The waterfall gets its water from Phnom Eysei Patamak or Phnom Svay near Ban Loung provincial town. From its upper level, the water flows from a small canal before dropping 25 meters to a lower level. Mountain slop leads visitors to the bottom of the waterfall, where they can sit inside a cave and enjoy the view.
