The Tad Sae Waterfall is 15 km southeast of Luang Prabang. This fall is one of the closer of two spectacular waterfalls that make good day trips from Luang Prabang. The water cascades down through several pools before flowing into the Khan River. During the dry season, the waterfall often has no water, and is not so spectacular. There are rarely any visitors at this time. Modest swimwear required so as not to cause offence to the mostly Lao visitors.
