This is one of plenty of the so called National Parks in the Kingdom, where the foreign visitor is being charged multiples! of the regular admission price. The amount of water flowing was so meager, hardly anyone would consider that a waterfall. The walkway from the parking lot is a nightmare and could badly need some attention by construction dudes. As waterfalls have in general a special appeal to Thais, they figure this is something special. Make sure to bring insect repellent and rough shoes if you need to see it. The flow may be improved in rainy season, but in December it was as poor as can be.
