Tat Fan is one of the most spectacular waterfalls in Laos. The twin streams of the Huay Bang Lieng plunge out of dense forest and tumble down more than 120m. The viewing point is at Tad Fane Resort , a jungle lodge that looks down onto the falls from the top of a cliff opposite. This resort and E-TU Resort both run guided treks to the top of the falls, usually in the morning; it takes a couple of hours to get there and back.
The turn-off to Tat Fan is clearly signposted 12km west of Paksong; from the turn-off it's about 800m to the waterfall on an unsealed road. Buses between Pakse and Paksong can drop you at the turn-off.
