It is not the most spectacular waterfalls but is conveniently located right along route 1093 to Phu Chi Fa. And there is a nice and well taken care park. And there are some Thai restaurants where you can rent a picknick set to enjoy a nice lunch along the water and even play in the water.
And if you are really boring you can take a little walk by taking the stairs right next to the waterfall to the plateau above the waterfall where you can walk a 900 meter jungle trail to the hot-water source of this waterfall. We did and while walking there you see some amazing huge trees. I love trees!
