The impressive waterfall on a side stream of the Rureng River. With ankle-deep water and gentle banks, the Rureng River is an easy walk. The rough road we were walking on went directly to the riverbed above the dam, however, so we continued walking upstream. The pretty Taiwan cotton rose, an endemic flower, lines the banks of the Rureng River.
