Ung Cha Waterfall is located about 8 kilometres west from the center of Banlung. The source of this waterfall is from the Svay Mountain where Wat Eisey Patamak is located. Below the waterfall is a cave-like pitch where visitors can stand or sit to watch the waterfall from behind and enjoy the cool mist sprayed gently by the wind.
