Sen Monorom waterfall is located in Sen Monorom district, about 5 kilometers northeast of the provincial town. The road to the waterfall passes numerous rubbers, coffee and cashew plantations. The site is very popular with local people during holidays and national festivals, because it is close to the provincial town. This waterfall also has three stages:

• First Stage: The water here flows slowly because the waterfall is only 1-meter-high and 2-meter-wide.
• Second Stage: The water flows faster here. In rainy season, the waterfall is 6 to 7 meters high and 8 meters wide; and in dry season, it is 7 to 9 meters high and 4 to 5 meters wide. There is a place to relax on the riverbank.
• Third Stage: The waterfall is 1.5 meters high and 1 kilometer from the second stage.
