The wide, multilevel cascade pools of this menthol-hued waterfall 15km southeast of Luang Prabang are a memorable sight from August to November. Unlike Tat Kuang Si, there's no single long-drop centrepiece and they dry up almost completely by February. But several year-round gimmicks keep visitors coming, notably a loop of 14 ziplines that allows you to 'fly' around and across the falls.
Part of the attraction of a visit is getting here on a very pleasant seven-minute boat ride (20,000K per person return, 40,000K minimum) that starts from Ban Aen, a peaceful Lao village that's just 1km east of Rte 13 (turn east at Km 371.5). A 30-minute tuk-tuk from Luang Prabang costs up to 150,000K return, including a couple of hours' wait.
