Ang Rue Nai Waterfall is located in Khao Ang Rue Nai Wildlife Sanctuary, in the middle of the fertile forest. Along the way, you will see various kinds of birds and maybe some rare exotic animals for example of Siamese Fireback which is the highlight of this Khao Ang Rue Nai Wildlife Sanctuary. The route to the waterfall is quite tough and deserted, no officers in charge. It is recommended to come as a group and inform the officer before entering the area every time for security reason.
