Tat Soung is a 50m drop. Unfortunately a new dam has substantially reduced the flow of this once-spectacular waterfall. If you walk 300m or so upstream from the top of the falls you'll find a delightful swimming hole. You can walk to Tat Soung with a guide, or ride a motorbike or bicycle to the top of the falls – head east out of town, pass Tadlo Lodge and follow the signs. It's about 10km.
