The most popular attraction at the falls is the nature trails because there is a huge tree of 4.77 meters diameter found here. The waterfall has 16 tiers created by multi-level stone cliffs which gives the impression of a giant stair. At the bottom is a vast pool with shallow water. The popular tier is tier 16 because this tier has a lot of moss on the stone.  This tier is named “Phanangleun”  Pha Nang Leun mean “Mrs. Slippery cliff” because the careless traveller can slip on the moss on a stone when he walks through.
