I'm glad there was a path to the waterfall after Mae Nam Viewpoint. It's very nice, it has many balconies where the water flows beautifully. You can dip in a bit to refresh.
Not too big waterfall, you can hike there from different starting points, it took us 2h to reach it. Be careful though as it's often slippery. Swimming was such a reward!
Beautiful nature but there is too much trash everywhere... Can get busy with people at the entrance. There is a nice trail in the park and many spots to see. I prefer hiring a motorbike and going there on my own rather than with the tour.
