This place is in Khao Khitchakut, just outside of Chanthaburi, it is the Khao Krathing Waterfall, and yes it does have a waterfall all though most of it is just rapids with a very steep slope.
Yes yet again it is 200baht for farangs to go in and another 30 baht for your car, don't you just love the government ripoffs? Na I doubt it.
You can also rent bungalows or pitch a tent here aswell.
